You’re probably brushing your teeth wrong – here are four tips for better dental health

<div class="theconversation-article-body"> <p><em><a href="https://theconversation.com/profiles/clement-seeballuck-583867">Clement Seeballuck</a>, <a href="https://theconversation.com/institutions/university-of-dundee-955">University of Dundee</a> and <a href="https://theconversation.com/profiles/nicola-innes-388237">Nicola Innes</a>, <a href="https://theconversation.com/institutions/university-of-dundee-955">University of Dundee</a></em></p> <p>We all know the advice for healthy teeth – brush twice daily and don’t eat too much sugar. So why do those of us following these instructions find we sometimes need a filling when we visit the dentist? The truth is, there’s a little more to preventing tooth decay than these guidelines suggest. Here’s what you need to know.</p> <h2>Brush up on your skills</h2> <p>How you brush makes a big difference. The mechanical act of brushing removes the very sticky dental plaque – a mixture of bacteria, their acids and sticky byproducts and food remnants. It forms naturally on teeth immediately after you’ve eaten but doesn’t get nasty and start to cause damage to the teeth until it reaches a certain stage of maturity. The exact amount of time this takes isn’t known but is at least more than 12 hours.</p> <p>Bacteria consume sugar and, as a byproduct, produce acids which dissolve mineral out of the teeth, leaving microscopic holes we can’t see. If the process isn’t stopped and they aren’t repaired, these can become big, visible cavities.</p> <p>Taking two minutes to brush your teeth is a good target for removing plaque and you should brush at night and one other time daily. Brushing frequently stops the bacteria developing to a stage where the species which produce the most acid can become established.</p> <p>Electric toothbrushes can be <a href="https://www.cochrane.org/CD002281/ORAL_poweredelectric-toothbrushes-compared-to-manual-toothbrushes-for-maintaining-oral-health">more effective than manual brushing</a> and a small toothbrush head helps to reach awkward areas in the mouth, while medium-textured bristles help you clean effectively without causing harm to gums and teeth. The main thing, however, is to get brushing!</p> <h2>Use fluoride toothpaste and disclosing tablets</h2> <p>Most of the benefit from brushing comes from toothpaste. The key ingredient is fluoride, which evidence shows <a href="https://www.cochranelibrary.com/cdsr/doi/10.1002/14651858.CD002278/full#CD002278-abs-0003">prevents tooth decay</a>. Fluoride replaces lost minerals in teeth and also makes them stronger.</p> <p>For maximum benefit, <a href="https://www.cochrane.org/CD007868/ORAL_comparison-between-different-concentrations-of-fluoride-toothpaste-for-preventing-tooth-decay-in-children-and-adolescents">use toothpaste with 1350-1500 ppmF</a> – that’s concentration of fluoride in parts per million – to prevent tooth decay.</p> <p>Check your toothpaste’s concentration by reading the ingredients on the back of the tube. <a href="https://theconversation.com/childrens-toothpaste-the-facts-80508">Not all children’s toothpastes are strong enough</a> for them to gain maximum benefit. Your dentist may prescribe higher strength fluoride toothpaste based on their assessment of your or your child’s risk of tooth decay.</p> <p>Plaque is difficult to see because it is whitish, like your teeth. Disclosing tablets are available in supermarkets and chemists and they make plaque more visible, showing areas you may have missed when brushing.</p> <h2>Spit, don’t rinse</h2> <p>At night, you produce less saliva than during the day. Because of this, your teeth have less protection from saliva and are more vulnerable to acid attacks. That’s why it’s important to remove food from your teeth before bed so plaque bacteria can’t feast overnight. Don’t eat or drink anything except water <a href="https://www.sign.ac.uk/assets/sign138.pdf">after brushing at night</a>. This also gives fluoride the longest opportunity to work.</p> <p>Once you’ve brushed, don’t rinse your mouth with water or mouthwash – you’re washing away the fluoride! This can be a difficult habit to break, but can <a href="https://www.sign.ac.uk/assets/sign138.pdf">reduce tooth decay by up to 25%</a>.</p> <h2>No more than four ‘sugar hits’</h2> <p>Intrinsic sugars are found naturally in foods like fruit and they are far less likely to cause tooth decay than added or <a href="https://www.bhf.org.uk/informationsupport/heart-matters-magazine/nutrition/sugar-salt-and-fat/free-sugars">free sugars</a>. Free sugars are generally those added to foods by manufacturers but also include honey, syrup and fruit juices.</p> <p>These are all easy for bacteria to consume, metabolise and produce acids from. However, it can be difficult to tell which are the worst sugars for teeth. For example, although normal amounts of fruit are fine, fruit juices have sugar liberated from the plant cells and heavy consumption can cause decay.</p> <p><a href="http://www.who.int/nutrition/publications/guidelines/sugars_intake/en/">The World Health Organization</a> and <a href="https://www.nhs.uk/common-health-questions/food-and-diet/how-much-sugar-is-good-for-me/">NHS</a> recommend free sugars should ideally make up less than 5% of your daily calorie intake. So what does this look like? For adults and children over about 11 years old, this is around 30g – about eight teaspoons – of sugar daily.</p> <p>A 330ml can of Coke has <a href="https://www.coca-cola.co.uk/drinks/coca-cola/coca-cola">35g of sugar</a>. The <a href="https://play.google.com/store/apps/details?id=com.phe.c4lfoodsmart&amp;hl=en_GB">change4life app</a> is helpful to track how much sugar you consume in your diet.</p> <p>Although not as important as how much, how often you eat sugar also matters. Simple carbohydrates like sugar are easier for bacteria to digest than proteins or complex carbohydrates. Bacteria produce acids after they metabolise sugar which causes demineralisation.</p> <p>Fortunately, through the actions of fluoride toothpaste and the remineralising effects of saliva, your teeth can recover from the early stages of these attacks. It’s like having a set of scales – trying to keep the balance between sugars on one side, fluoride toothpaste and cleaning on the other.</p> <p>Typically, your teeth can be exposed to four “sugar hits” – episodes of sugar intake – daily without irreversible damage to the teeth. Why not try counting how many sugary hits you have a day? This includes biscuits, cups of sugary tea or coffee and other snacks with refined carbohydrates like crisps. A simple way of cutting down would be to stop putting sugar in hot drinks and limiting snacking.</p> <p>Brush twice daily with fluoride toothpaste, spit don’t rinse, eat and drink nothing after brushing, and don’t have sugar more than four times daily.

Doctor shares her holy grail tips for overcoming eye sensitivity

<p>As the chill of winter sets in, many people find that their eyes become more sensitive and prone to dryness. This can be particularly challenging for those who already suffer from dry eye syndrome. </p> <p>Dr. Jacqueline Beltz is a leading Australian Ophthalmologist and the founder of <a href="https://www.okkiyo.com" target="_blank" rel="noopener">OKKIYO</a>, a beauty brand that makes PRIORITEYES mascara for people with sensitive eyes.</p> <p>Dr Beltz has shared her insights into dry eye syndrome and how winter can exacerbate symptoms, also sharing her top tips for managing eye sensitivity during the colder months.</p> <p><strong>Understanding Dry Eye Syndrome</strong></p> <p>The surface of the eye is covered by a delicate layer of tears, essential for comfort, vision, protection, and nutrition. The tear film comprises two main layers: an outer lipid (oily) layer and an inner aqueous (watery) layer. The lipid layer, produced by oil glands in the eyelids, prevents tears from evaporating too quickly, while the aqueous layer, consisting of water, electrolytes, and proteins, spreads tears evenly across the eye and helps them adhere to the surface.</p> <p>When the balance of tear production, evaporation, absorption, and drainage is disrupted, it can lead to dry eye syndrome. Symptoms may include redness, irritation, a gritty sensation, tired eyes, itching, excessive watering, and fluctuating vision. In severe cases, dry eye can be painful and significantly impact daily life.</p> <p><strong>How common is dry eye syndrome?</strong></p> <p>Dry eye syndrome is a widespread issue, particularly among older adults. According to the Blue Mountains Eye Study, 57% of adults over the age of 50 experience some degree of dry eye. This condition is notably more prevalent in women, with higher rates observed compared to their male counterparts. The increased prevalence in women is often attributed to hormonal changes, particularly during and after menopause. </p> <p>A more recent study, Optometry Australia’s 2022 Vision index found that over 85% of Australians are estimated to have experienced dry eyes at some point in their lives.  Of those affected, 55% say they only developed the condition following the beginning of the pandemic in 2020.  They reported that almost 1 in 5 (18%) of people experience dry eye symptoms frequently.  </p> <p>These statistics highlight the importance of understanding and managing dry eye, especially as we age.</p> <p><strong>DEWS II Study and Treatment Approaches</strong></p> <p>The DEWS II (Dry Eye Workshop II) study provides a comprehensive framework for understanding and treating dry eye syndrome. According to the study, dry eye is a multifactorial disease characterised by a loss of homeostasis (or balance) in the tear film, accompanied by eye symptoms. Factors such as tear film instability, hyperosmolarity (increased saltiness), inflammation, and neurosensory (altered feelings or sensations) abnormalities play significant roles.</p> <p>There are two primary types of dry eye: aqueous deficient and evaporative. Most individuals have a combination of both. Aqueous deficient dry eye occurs when there is insufficient production of the watery layer of tears, often due to aging, hormonal changes, or certain medications. Evaporative dry eye is typically caused by environmental factors or conditions affecting the lipid layer, such as meibomian gland dysfunction (MGD).</p> <p><strong>Winter's Impact on Dry Eyes</strong></p> <p>Winter poses unique challenges for dry eye sufferers. Cold, dry air, indoor heating, and wind can all exacerbate symptoms. Here's how to combat these winter-specific issues:</p> <p><em><strong>1. Humidify Your Environment</strong></em></p> <p>Indoor heating reduces humidity levels, leading to increased tear evaporation. Consider using a humidifier to maintain moisture in the air, especially in bedrooms and living spaces. This helps keep your eyes hydrated.</p> <p><em><strong>2. Protect Your Eyes Outdoors</strong></em></p> <p>Cold winds can strip away the tear film. When outside, wear wraparound sunglasses to shield your eyes from the elements. This not only protects your eyes from the wind but also from UV rays, which can be strong even in winter.</p> <p><em><strong>3. Stay Hydrated</strong></em></p> <p>Dehydration can worsen dry eye symptoms. Drink plenty of water throughout the day to maintain overall hydration, which supports healthy tear production.</p> <p><em><strong>4. Optimise Your Diet</strong></em></p> <p>Certain foods can promote eye health. Omega-3 fatty acids, found in fish like salmon and flaxseeds, have anti-inflammatory properties that can help manage dry eye symptoms. Incorporate these into your diet for added benefits.</p> <p><em><strong>5. Use a Warm Compress</strong></em></p> <p>A warm compress can help improve the function of the meibomian glands, which produce the oily layer of the tear film. This is particularly helpful for those with meibomian gland dysfunction, or MGD. Gently apply a warm, damp cloth to your closed eyelids for 10-15 minutes, followed by a gentle massage of the eyelids to encourage oil secretion. It is important to avoid rubbing or compressing the eyeballs.</p> <p><em><strong>6. Use Over-the-Counter Lubricant Eye Drops</strong></em></p> <p>Artificial tears can provide temporary relief by supplementing the natural tear film. Choose preservative-free options to avoid further irritation, and use them frequently.</p> <p><em><strong>7.  Remember to have regular eye checks</strong></em></p> <p>In Australia, Optometrists provide our primary eye health check ups. Dr Beltz recommends adults over the age of 40 see their optometrist once a year, but if you’re struggling with symptoms of dry eye in winter, an extra check up might help and your optometrist will be able to help you to come up with an individualised treatment plan.</p> <p><em><strong>8. Invest in Quality Eye Products</strong></em></p> <p>For those who wear makeup, using products designed for sensitive eyes is crucial. <a href="https://www.okkiyo.com/products/protect-and-preserve-mascara" target="_blank" rel="noopener">PRIORITEYES</a> mascara by OKKIYO has been specifically formulated to be gentle on sensitive eyes, avoiding common irritants while providing excellent performance.</p> <p><strong>Managing Dry Eye in Winter: A Recap</strong></p> <p>Winter can be tough on our eyes, but with the right strategies, you can manage dry eye symptoms effectively. Maintain a humid environment, protect your eyes from cold winds, stay hydrated, and incorporate eye-healthy foods into your diet. Regularly use warm compresses and opt for gentle, high-quality eye products like PRIORITEYES mascara.  </p> <p>Dry eye syndrome may be a common condition, but it doesn't have to dominate your life, especially during the harsh winter months. With these tips, you can keep your eyes comfortable and healthy all season long. For personalised advice and treatment, always consult with your eye care professional.</p> <p>Stay warm, stay hydrated and take care of your eyes this winter!</p> <p><em>Image credits: Shutterstock </em></p>

"Am I being too sensitive?": Woman's dilemma after partner forgets 60th birthday

<p>A woman has shared her dilemma on how to approach her partner of 30 years, after he forgot her 60th birthday. </p> <p>"It's my 60th birthday today, and my partner of 30 years has not acknowledged it. Should I tell him?" she titled her post on Reddit. </p> <p>"It's my actual birthday today, and whilst we have planned a big party for next weekend, when I woke up this morning I expected a 'Happy Birthday!' and a smile," she continued. </p> <p>"I didn't get anything. He started my coffee but he does that almost every morning.</p> <p>"At first I thought maybe he forgot but now I am thinking that he thinks he doesn't have to say anything because we are having a big party this weekend. </p> <p>"Am I being too sensitive? Should I tell him? If so, how?" she asked in her post. </p> <p>Hundreds of Reddit users took to the comments to share their thoughts on how to approach the situation, with a few sharing crafty solutions of their own. </p> <p>"I'd make a joke of it. 'I can't believe they moved my birthday!' Or 'I saw on the TV we should ask easy questions to check for dementia- I'll ask you first, when's my birthday?'" one user playfully suggested. </p> <p>"I'm going to say the absolute minimum I'd expect for ANY birthday is my wife wishing me a Happy Birthday. Don't let it fester and ruin your day - just ask him about it" another added. </p> <p>One user saw the bright side of things and said:  "He's handed you the best birthday present of all - the opportunity to use this against him for the next twenty years.</p> <p>"I'd be rubbing my hands with glee. Happy Birthday!" </p> <p>"Happy Birthday. Go out and buy a large cake. Eat it all yourself. Nobody need ever know" to which she responded: "there is a Costco not that far away. Go big or go home." </p> <p>Another Redditor came up with an elaborate plan on how she could get her partner's attention. </p> <p>"Purchase this 'Acknowledge Me' t-shirt of WWE wrestle Roman Reigns. Then write 'Birthday' on a piece of card and use some tape to stick on the t-shirt. 'Acknowledge Me Birthday.' Then just wear it around the house," they said. </p> <p>The woman was onboard with the plan, but luckily she didn't need to apply any of their crafty solutions and shared an update. </p> <p>"He just came up to my home office and gave me a big hug, admitting he had forgotten because he was so focussed on both work and next weekend's party," she wrote. </p> <p>"He apologised sheepishly, which was exactly the best outcome possible. Now I have both my birthday acknowledged as well as a fine story and/or bit of ammo to be saved for another day.</p> <p>"So there you go. I've cancelled the 'acknowledge me' t-shirt order, and shall now share my Costco cake with him instead of eating it from across the table, glaring.</p> <p>"Thank you everyone for the very fine passive aggressive suggestions which made me smile. Much appreciated!"</p> <p><em>Image: Getty</em></p> <p> </p>

"Thoughtful and sensitive": The Crown's plan to recreate Diana's death

<p><em>The Crown</em> have announced that they will be covering the death of Princess Diana in the upcoming season of the show, saying they will be handling the recreation "carefully". </p> <p>The Netflix drama based on the story of the royal family will be returning later this year for season six, which is expected to be the final season of the show. </p> <p>The final season of <em>The Crown</em> is set to take place between the years of 1997 to the early 2000s, including a delicate recreation of the death of the late Princess of Wales. </p> <p>Producer of the show Suzanne Mackie spoke of the upcoming season at the Edinburgh International Conference Centre, saying it took a long and careful conversation to reach the decision to cover Diana's death on the show. </p> <p>She said, "The show might be big and noisy, but we're not. We're thoughtful people and we're sensitive people."</p> <p>"And so there was a very, very careful, long, long, long conversation about how we do it – and I hope, you know, the audience will judge it in the end, but I think it's been delicately, thoughtfully recreated."</p> <p>Australian actress Elizabeth Debicki will be returning as Diana after her portrayal of the late Princess in season five. </p> <p>Mackie said Debicki was an "extraordinary actress" who treated the subject carefully.</p> <p>"She was so thoughtful, considerate and loved Diana," Mackie said.</p> <p>"So there was a huge amount of respect from us all. I hope that's evident when you see it."</p> <p>Season six of the show is also set to include the early days of Prince William and Kate Middleton's love story, beginning when they met while at St Andrew's University in Scotland in 2001. </p> <p><em>Image credits: Getty Images</em></p>

What it means when your teeth fall out in a dream

<p dir="ltr">Dreaming of your teeth falling out is never pleasant, but surprisingly and unfortunately they’re one of the most common types of dreams people experience and there are a few reasons why. </p> <p dir="ltr" role="presentation"><strong>1. Insecurity or shame</strong></p> <p dir="ltr">Dreams often represent feelings more than literal symbolism, and teeth falling out can represent issues with confidence and self-esteem. To interpret this dream, think about any areas of your life where you are experiencing shame or self-doubt.</p> <p dir="ltr"><strong>2. Rebirth or transformation</strong></p> <p dir="ltr">A theory popularised by renowned psychiatrist Carl Jung suggests that teeth falling out in a dream could represent a type of rebirth or transformation. Losing teeth is not necessarily a bad omen, but rather could be a sign of growth or positive changes, as adult teeth come in afterwards.</p> <p dir="ltr"><strong>3. Loss or grief</strong></p> <p dir="ltr">Losing teeth in a dream could represent a real-life loss or grief, and if the subconscious is trying to assimilate a real-life loss, it could lead to ‘losing’ things or parts of you in your sleep.</p> <p dir="ltr"><strong>4. Lack of control </strong></p> <p dir="ltr">Another popular idea is that losing your teeth in a dream is about control, more so a lack thereof. It’s important to consider if there is something in your life that makes you feel powerless, such as an issue out of your control or a sudden change.</p> <p dir="ltr"><strong>5. Literal dental issues</strong></p> <p dir="ltr">There is a possibility that dreaming of your teeth falling out could represent literal dental issues. Researchers in the Frontiers in Psychology study found that teeth dreams often correlated with dental irritation. </p> <p dir="ltr"><em>Image credit: Shutterstock</em></p>

19 handy uses for toothpaste that have nothing to do with your teeth

<h2>Remove scuffs from shoes</h2> <p>A little toothpaste does an amazing job of removing scuffs from leather shoes. Just squirt a dab on the scuffed area and rub with a soft cloth. Wipe clean with a damp cloth. The leather will look like new.</p> <h2>Clean your piano keys</h2> <p>Has tickling the ivories left them a bit dingy? Clean them up with toothpaste and a toothbrush, then wipe them down with a damp cloth. Makes sense, since ivory is essentially elephant teeth. However, toothpaste will work just as well on modern pianos that usually have keys covered with plastic rather than real ivory.</p> <h2>Clean your sneakers</h2> <p>Want to clean and whiten the rubber part of your sneakers? Get out the non-gel toothpaste and an old toothbrush. After scrubbing, clean off the toothpaste with a damp cloth.</p> <h2>Clean your clothes iron</h2> <p>The mild abrasive in non-gel toothpaste is just the ticket for scrubbing the gunk off the bottom plate of your clothes iron. Apply the toothpaste to the cool iron, scrub with a rag, then rinse clean.</p> <h2>Polish a diamond ring</h2> <p>Put a little toothpaste on an old toothbrush and use it to make your diamond ring sparkle instead of your teeth. Clean off the residue with a damp cloth.</p> <h2>Deodorise baby bottles</h2> <p>Baby bottles inevitably pick up a sour-milk smell. Toothpaste will remove the odour in a jiffy. Just put some on your bottle brush and scrub away. Be sure to rinse thoroughly.</p> <h2>Prevent fogged goggles</h2> <p>Whether you are doing woodworking or going skiing or scuba diving, nothing is more frustrating (and sometimes dangerous) than fogged goggles. Prevent the problem by coating the goggles with toothpaste and then wiping them off.</p> <h2>Prevent bathroom mirrors from fogging</h2> <p>Ouch! You cut yourself shaving and it’s no wonder – you can’t see your face clearly in that fogged-up bathroom mirror. Next time, coat the mirror with non-gel toothpaste and wipe it off before you get in the shower. When you get out, the mirror won’t be fogged.</p> <h2>Shine bathroom and kitchen chrome</h2> <p>They make commercial cleaners with a very fine abrasive designed to shine up chrome, but if you don’t have any handy, the fine abrasive in non-gel toothpaste works just as well. Just smear on the toothpaste and polish with a soft, dry cloth.</p> <h2>Clean the bathroom sink</h2> <p>Non-gel toothpaste works as well as anything else to clean the bathroom sink. The tube’s sitting right there, so just squirt some in, scrub with a sponge, and rinse it out. Bonus: the toothpaste will kill any odours emanating from the drain trap.</p> <h2>Remove crayon from walls</h2> <p>Did crayon-toting kids get creative on your wall? Roll up your sleeves and grab a tube of non-gel toothpaste and a rag or – better yet – a scrub brush. Squirt the toothpaste on the wall and start scrubbing. The fine abrasive in the toothpaste will rub away the crayon every time. Rinse the wall with water.</p> <h2>Remove ink or lipstick stains from fabric</h2> <p>Oh no, a pen opened up in the pocket of your favourite shirt! This may or may not work, depending on the fabric and the ink, but it is certainly worth a try before consigning the shirt to the scrap bin. Put non-gel toothpaste on the stain and rub the fabric vigorously together. Rinse with water. Did some of the ink come out? Great! Repeat the process a few more times until you get rid of all the ink. The same process works for lipstick</p> <h2>Remove watermarks from furniture</h2> <p>You leave coasters around. But some people just won’t use them. To get rid of those telltale watermark rings left by sweating beverages, gently rub some non-gel toothpaste on the wood with a soft cloth. Then wipe it off with a damp cloth and let it dry before applying furniture polish.</p> <h2>Clear up pimples</h2> <p>Dab a bit of non-gel, non-whitening toothpaste on the offending spot, and it should be dried up by morning. The toothpaste dehydrates the pimple and absorbs the oil. This remedy works best on pimples that have come to a head. Caution: this remedy may be irritating to sensitive skin.</p> <h2>Clean smells from hands</h2> <p>The ingredients in toothpaste that deodorise your mouth will work on your hands as well. If you’ve gotten into something stinky, wash your hands with toothpaste, and they’ll smell great.</p> <h2>Stop bug bites from itching</h2> <p>Put toothpaste on your bug bite to keep it from itching. Dab a dime-sized amount onto your bug bite. This method also helps to cool down burns on your skin.</p> <h2>Remove a stain from the carpet</h2> <p>Rub toothpaste into the stain on the carpet with a toothbrush or sponge. Rinse with water and repeat until the stain comes up.</p> <h2>Clean your foggy headlights</h2> <p>Make the headlights on your car shine like new. Put toothpaste onto a sponge and scrub your headlight in circular motions. Wipe the toothpaste off with a damp cloth.</p> <h2>Remove small scratches from your phone screen</h2> <p>Rub toothpaste on the front or back of your phone (wherever there are scratches). The toothpaste will work to reduce the look of the scratches and make your phone screen look much better.</p> <p><em>Image credit: Shutterstock</em></p> <p><em>This article originally appeared on <a href="https://www.readersdigest.com.au/food-home-garden/diy-tips/19-handy-uses-for-toothpaste-that-have-nothing-to-do-with-your-teeth" target="_blank" rel="noopener">Reader's Digest</a>. </em></p>

Mandatory sensitivity training for Kyle Sandilands

<p> KIIS FM have been led to employ a second censor to monitor the talkshow and will provide sensitivity training to Kyle Sandilands after a breach in decency standards during a segment about the Paralympics.</p> <p>The ruling was given by the Australian Communications and Media Authority (ACMA) regarding two episodes of the breakfast talkshow in September 2021.</p> <p>In one of the segments, the radio giant referred to the 2020 Tokyo Paralympics as “horrific” as well as dubbing it the “Special Olympics”.</p> <p>“Have you been watching the Special Olympics [sic], it is horrific some of the things,” Sandilands told his co-host Jackie ‘O’ Henderson.</p> <p>“Some poor bloke ran for the high jump and then veered right ’cause he was blind and landed on his a**e on the ground,” he continued.</p> <p>Sandilands claimed to respect “the spirit of the contest” on-air but added, “Listen, you can be nice to the handicapped, but you don’t have to compare them to the non-handicapped.”</p> <p>In its defence, KIIS FM highlighted that its audience was used to Kyle’s “low-level coarse language that is ordinarily reserved for private conversation”.</p> <p>“Mr Sandilands is well-known for his turn of phrase, colourful vernacular and blunt manner,” stated the defence.</p> <p>“The audience somewhat ‘self-selects’ so that those that choose to listen are not offended by this manner. Our expectation is that regular Kyle &amp; Jackie listeners would not have been offended by the Paralympics segment.”</p> <p>ACMA, however, found in its report that the segment would have been offensive to more than just the athletes but the broader community as well.</p> <p>“Mr Sandilands’ comments were insensitive and hurtful toward the athletes as well as being offensive to the average moderate person in the broader community, including the regular audience of the program, who would have been aware of the potential impact of these comments, not only on the Paralympians that were being described in this manner, but on the wider group of people in Australia with disabilities,” ACMA said.</p> <p>It also saw another breach when Sandilands threatened a <em>news.com.au</em> journalist over an article that criticised him, which led to him saying on air that said reporter should “expect a visit from me”.</p> <p>According to ACMA, the remarks “offended against generally accepted standards of decency”.</p> <p>KIIS FM will now be required to maintain two censors and sensitivity training will be provided to both hosts, producers and other relevant staff.</p> <p>It has also agreed to review its controls to prevent further breaches.</p> <p><em>Image credit: Getty</em></p>

9 habits that secretly annoy your dentist

<h2>The importance of maintaining dental health</h2> <p>Maintaining good dental health does more than just keep your pearly whites bright. Recent research – such as one 2020 study – has found that poor oral hygiene is connected with other physical conditions, such as diabetes and heart disease.</p> <p>A recent report from the American Heart Association also found a link between poor dental care and declining brain health. But even if you’re brushing, flossing, and up-to-date with professional cleanings, dentists say many of us are guilty of some lifestyle and oral health habits that could be doing our mouths more harm than good.</p> <h2>Your love for citrus</h2> <p>Most people are aware that soft drinks are damaging to teeth, says dentist, Dr Arthur Jeske. “Others may be less obvious,” Dr Jeske says, like your morning smoothie with a squirt of lime juice or the lemon wedge you add to a beer or cocktail. This is because the high acidity levels in many fruits (even grapes and peaches are quite acidic) can cause demineralisation, “which means [they] can literally dissolve your tooth enamel over time.”</p> <p>Dr Jeske’s recommendation: drinking plain water after eating or drinking can help reduce fruits’ impact on your teeth.</p> <h2>That firm toothbrush</h2> <p>“Many people believe brushing with firmer toothbrush bristles and abrasive toothpaste will make their teeth cleaner and whiter,” says dental surgeon, Dr James Galati. But these products (and heavy-handed brushing in general) can actually damage teeth by taking off the protective enamel and traumatising gum tissue around the teeth – leading to receding gums and root exposure. Instead, aim for soft-bristle brushes and toothpastes with fluoride.</p> <h2>Overusing whitening toothpastes</h2> <p>Toothpastes vary widely in their abrasiveness, Dr Jeske explains. A product’s Relative Dentin Abrasion Value (RDA) is categorised by low, medium, and high abrasiveness.</p> <p>If you brush frequently, for instance, you may want to stick with a product on the lower end of the spectrum (this ranges from zero to 250, and Dr Jeske says you can look up the RDA for specific products online). But he points out that most whitening toothpastes tend to be among the more abrasive. That doesn’t mean you have to avoid them altogether, but he recommends using them less frequently in your routine and swapping in a gentler toothpaste to avoid excessive wear.</p> <h2>Brushing right after eating</h2> <p>It’s important to wait 15 to 30 minutes after eating or drinking before brushing your teeth, says dentist, Dr Jacquelyn Schieck. “[This time] allows the pH of the mouth to revert to neutral, which prevents brushing away enamel that’s been softened by acids in foods or beverages.”</p> <h2>Improper flossing</h2> <p>If you floss daily, you’re already ahead of the curve when it comes to your dental health. Population research is limited, but according to the Australian Dental Association only 25 per cent of Australian adults floss their teeth every day. So three quarters of Australian adults don’t floss daily.</p> <p>Still, “while flossing is considered a ‘gold standard’ for cleaning between the teeth and promoting gum health, it may not be as effective if used improperly,” Dr Jeske explains. For example, interdental cleaners – tiny, round brushes with handles – are recommended over string floss for certain people, such as those with more advanced gum disease. Your dentist and dental hygienist can advise you on what type of floss is best for you and how to use it effectively.</p> <p>Flossing technique is important, too: you want to be sure to thread your floss into your gums to make sure you’re effectively loosening food and other debris.</p> <h2>Charcoal toothpaste</h2> <p>Dr Galati says that one of the more potentially harmful internet fads he’s seen is charcoal-based toothpaste, powders, or tabs. These products are often promoted as eco-friendly, ‘natural’ teeth cleaners that can remove surface stains to whiten teeth and absorb bacteria that cause bad breath.</p> <p>But Dr Galati says that most charcoal-based toothpastes are very abrasive and can cause damage that makes your teeth more susceptible to decay and bone loss. Plus, “there are no studies showing they whiten teeth any better than standard toothpastes,” he says.</p> <h2>Your high stress levels</h2> <p>High stress levels and a demanding work or life environment have been linked to increased dental health problems, Dr Galati says. Stress can make you more prone to grinding and clenching your teeth, for example, which leads to excessive wear. Unconscious nervous habits like chewing on fingernails, hairpins, pen caps, or ice can cause similar damage, Dr Shieck adds.</p> <h2>Lying to your dentist</h2> <p>Medical professionals are there to help you, not judge your habits. Accurate information – including your lifestyle habits like smoking, vaping, diet, and alcohol use, dental habits, and medications or supplements you take – is crucial for your dentist to properly identify dental problems and design the optimal treatment plan. “Some misrepresentations are easy to detect,” Dr Jeske says, like if someone says they brush and floss twice a day but their gums bleed during a dental exam. “But others may confuse the diagnosis or delay it, resulting in additional harm,” (and often, financial costs.)</p> <h2>DIY orthodontics</h2> <p>“[This] is one of the most dangerous and concerning fads I’ve seen online,” says Dr Schieck. The movement of teeth is a complex biological process that requires a highly-trained doctor’s oversight to avoid harmful consequences. “It’s amazing what people will try,” she says. “But trying at-home aligner systems in the absence of orthodontic guidance, using elastics or other household items to move teeth, or even attempting to 3D-print appliances yourself is not safe or effective.”</p> <p><em>This article originally appeared on <a href="https://www.readersdigest.com.au/healthsmart/9-habits-that-secretly-annoy-your-dentist" target="_blank" rel="noopener">Reader's Digest</a>. </em></p> <p><em>Images: Getty</em></p>

New censorship target for "sensitivity readers"

<p>Enid Blyton is known around the world, across all generations, as the author behind the children’s classics <em>The Magic Faraway Tree</em>, <em>The Adventures of the Wishing Tree</em>, <em>Noddy</em>, and <em>The Famous Five</em>. </p> <p>And now, the late Blyton is also known as the latest author to face edits and rewrites at the hands of her publisher, Hodder Children’s Books. They have confirmed that they will be carrying out the work to remove “offensive terms” as part of their “ongoing process”. </p> <p>Such changes have made the news already in 2023 - people had a lot to say about proposed edits to Roald Dahl’s books. Edits like those to Dahl’s work, dubbed by critics as “woke”, see publishers rewriting older texts after feedback from sensitivity readers, and removing certain terms that are deemed to be offensive to modern audiences. </p> <p>According to a report by <em>The Australian</em>, an audiobook version of one of <em>The Famous Five</em> books, a collection of short stories, has undergone edits to remove the words “idiot”, “a**”, and “shut up”.</p> <p>One story sees cousins Julian, Dick, George, Anne, and their canine companion Timmy, investigate lights on the island - Kirrin Island - by George’s home. In a bid to get their adventure started, George wakes her cousin Anne, and Anne tells her “oh George, don’t be an a**.”</p> <p>In the new edition, Anne simply says “oh George.” </p> <p>Meanwhile, in the original text, Anne’s big brother - and George’s cousin - Julian, at one point tells George to “shut up” and “be sensible”. Now, Julian only tells her “George, be sensible.” </p> <p>Additionally, two other instances of characters being told “don’t be an idiot” have been removed.</p> <p>Those particular phrases still feature in a Hodder Children’s Books e-book version of the text, though “a**” remains unseen, substituted in this case with “idiot”. </p> <p>The publishing house previously faced backlash in 2010 when they put out “contemporary” adaptations of Blyton’s books, replacing the likes of “headmistress” with “teacher”.</p> <p>These revisions were seemingly put to rest when Hodder Children’s Books declared that they weren’t working. </p> <p>“The feedback we have had six years on shows that the love for The Famous Five remains intact, and changing mother to mummy, pullover to jumper, was not required,” Anne McNeil, their publishing director, explained to The Guardian in 2016. “We want Enid Blyton’s legacy to go on. Millions of readers have learned to read with her.”</p> <p>However, as a 2023 statement reads, the publisher’s parent company - Hachette UK - consider the edit of Blyton’s books to be an “ongoing process”, as part of their “intention to keep Enid Blyton’s books and stories at the heart of every childhood, as they have been for generations.” </p> <p>“To do so, we work to ensure that there are no offensive terms in the books - changing words where the definition is unclear in context and therefore the usage is confusing, and where words have been used in an inappropriate or offensive sense - while retaining the original language as far as is possible,” a spokesperson for the company said. “This enables a very wide international audience of children to enjoy the books, while also understanding that they were written and set in the past.</p> <p>“In new editions, we do not change language for the sake of modernising it. We retain old-fashioned terms such as ‘bathing-suit’ and references to pre-decimal currency. The books’ period setting is part of their charm and is enjoyed by readers of all ages.</p> <p>“Any historic changes previously made to new editions, which come under the category of ‘modernisation’ in this context, have been or are being restored to the original text at the point of reprint.”</p> <p><em>Images: Getty</em></p>

The part of your teeth you’ve been forgetting to brush

<p>Like so many things in life, brushing your teeth is a matter of quality over quantity. There’s no point in brushing your teeth four times a day if you’re doing it the wrong way.</p> <p>Jessica Hilburg, DDS and associate dean for clinical affairs at the NYC College of Dentistry, was recently asked by the Huffington Post about the most-common errors people make when they give their mouth the old once-over.</p> <p>"Sometimes people forget to brush the insides of their teeth, the surfaces that face the tongue and the palate," Hilburg said. "Sometimes people forget these areas because we don't see them when we look in the mirror. Food and plaque can buildup in these areas so it's just as important to brush there as it is on the front of our teeth where we can easily see."</p> <p>Hilburg added not brushing your teeth long enough or using the wrong amount of pressure while brushing your teeth is equally incorrect and can ultimately be damaging.</p> <p>"Applying too much pressure while brushing could damage gums and be abrasive to the teeth," she said. "Applying too little pressure while brushing just isn't as effective and will not remove the plaque as well as using gentle pressure. (Also) just rubbing the toothbrush back and forth in long strokes will not do as good a job as the short strokes because the short strokes allow you to get in between the teeth much better."</p> <p>She added, "The 'right amount of pressure' is pressure that feels comfortable, does not crush the bristles of the toothbrush (too much pressure) and of course leaves your teeth feeling and looking clean."</p> <p>What are your thoughts?</p> <p><em>Image: Getty</em></p>

Dentist slams dangerous “aesthetic” teeth hacks

<p dir="ltr">A dental surgeon has slammed a series of online hacks that show people attempting their own DIY dental work to achieve the perfect smile. </p> <p dir="ltr">Prominent Queensland dental surgeon Dr Heath Fraser has argued against grim TikTok viral trends that have people trying to whiten and straighten their teeth at home, saying these “tips” can cause serious damage. </p> <p dir="ltr">Among the worst offenders was a woman who filmed herself filing down her teeth using a nail file and promoted the tactic as a cheap way to get a straight smile. </p> <p dir="ltr">The bizarre video amassed thousands of views, with copycat users claiming they had also tried the hack and experienced no lasting damage. </p> <p dir="ltr">Dr Fraser, however, revealed people who filed their teeth could be setting themselves up for “invasive procedures such as fillings, crowns, veneers and even root canal treatment to resolve the erosion issue”.</p> <p dir="ltr">He described filing teeth as “highly irresponsible” and explained that “once tooth enamel has been removed it is impossible to regenerate”.</p> <p dir="ltr">“Even when performed in the dental chair by a professional, patients run the risk of eroding their tooth enamel,” he said.</p> <p dir="ltr">Other problematic “hacks” saw millions of TikTok users exposed to highly dangerous teeth whitening methods involving the use of household cleaners and hydrogen peroxide as a teeth scrub.</p> <p dir="ltr">Dr Fraser said there were enormous consequences for people who used these products on their teeth, saying they posed “irreversible risks to the health of your teeth”.</p> <p dir="ltr">Other users were desperate to straighten their teeth, as they shared how they tried using elastic hair bands in place of braces.</p> <p dir="ltr">Dr Fraser condemned the method, as one video racked up millions of views promoting the use of elastic bands. </p> <p dir="ltr">“Using elastic bands may work to move your teeth, but not in the aesthetic way you probably desire. The thin, tight elastic bands used by users on social media can penetrate the gum, severely damaging the soft tissue in your mouth which may ultimately lead to serious irreversible damage, including your tooth falling out from the root,” he said.</p> <p dir="ltr">Dr Fraser reminded people that for any dental work, attending a dentist is always the safest and most effective option. </p> <p dir="ltr"><em>Image credits: TikTok</em></p>

4 ways to straighten your teeth

<div title="Page 1"> <div> <div> <p>Crooked and misaligned teeth are common in many children and adults. If your teeth are not severely crooked, there’s no need to straighten them. However, if you’re hiding your smile and the condition is taking a toll on your confidence or causing speech or health issues, modern dentistry makes it possible to realign them.</p> <p>In this article, we share some dental procedures to help straighten your smile or at least reduce the appearance of slightly crooked or misaligned teeth.</p> <p><strong>1. Braces </strong></p> <p><strong> </strong></p> <p>In terms of straightening teeth, metal braces are the most popular procedure used. Braces are a great choice for people of any age, provided that their gums and teeth are strong enough to hold them. It’s particularly beneficial for kids who still have flexible and malleable bone tissues and gums.</p> <p>In general, braces work by exerting constant pressure on your jaws and teeth to change their position and straighten your smile. Due to the gradual pressure, the treatment can take about two to three years, subject to the dental brace type you choose and the severity of teeth misalignment. You may choose from the following types of dental braces:</p> <p>● Metal Braces</p> <p>This is what most people think of when talking about braces. This classic brace comes with individual brackets glued and attached to each tooth. A flexible archwire then connects each bracket, putting pressure on your jawline and teeth. This archwire is attached to the brackets using elastic O-rings.</p> <p>Metal braces are often the best choice for someone with more complicated dental alignment problems.</p> <p>● Invisible Braces</p> <p>This type of dental brace is nearly invisible and is meant to be worn by adults and teens only. Unlike metal braces, invisible braces like Invisalign use clear plastic aligners that are custom- made to fit your teeth. They have a snug fit, much like a mouth guard, that creates pressure and gradually moves your teeth into position. In general, this should be removed and replaced twice a month to ensure a perfect fit.</p> <p>Take note, however, that invisible braces may take a lot longer to straighten your teeth than metal braces. The upside is that it’s painless and more flexible than traditional braces. You may check out the <a href="https://www.ariadental.net.au/dental-articles/how-does-invisalign-work/" target="_blank" rel="noopener">Invisalign procedures explained</a> online if you want to learn more.</p> </div> </div> </div> <div title="Page 2"> <div> <div> <p>● Ceramic Braces</p> <p>Ceramic braces work like metal braces; however, they are less visible and more discreet. This is because ceramic braces are made of clear, tooth-coloured material, so they don’t stand as much as metal brackets.</p> <p>Ceramic braces are popular among patients who want the aligning power of braces but want it to be discreet like Invisalign. They are also more affordable than metal braces, making them an appealing option for those on a budget.</p> <p>However, ceramic braces are slightly bigger than metal braces. Besides, depending on your brushing habits and diet, ceramic braces may be prone to staining. They are also less durable than metal brackets and can break easily.</p> <p>● Lingual Braces</p> <p>Did you know that the side of your teeth facing your tongue is called the lingual surface? That said, lingual braces are a type of invisible braces placed on this surface. This means that brackets are attached to the back sides of your teeth.</p> <p>Lingual braces are the most specialised and least common type of braces available. This is because they require a different set of orthodontic skills. Due to their rarity, lingual braces can be expensive.</p> <p>Because they are placed in the teeth, it’s best for those who don’t want noticeable braces. This type of dental brace may also take longer to work and get used to. Plus, it’s more difficult to clean. Lingual braces are also not suitable for severely crooked or misaligned teeth but are more effective in correcting most bite issues.</p> <p>● Self-Litigating Braces</p> <p>Self-litigating braces are similar to metal and ceramic braces, relying on brackets and wires to move your teeth into place. The only difference is that self-litigating braces use brackets with clips or doors to hold the wire, instead of an elastic rubber O-ring.</p> <p>Like traditional metal braces, self-litigating braces will still need periodic adjustments. However, orthodontist visits are generally shorter because your dentist only needs to open, adjust, and shut the self-litigating brackets instead of replacing individual O-rings. Self-litigating braces are also easier to clean because there are no rubber ligatures that trap food particles. Likewise, some patients experience less discomfort with self-litigating braces.</p> <p><strong>2. Veneers </strong></p> <p><strong> </strong></p> <p>Veneers are wafer-thin shells of tooth-coloured materials attached to the front of your teeth. This helps cover minor imperfections, including discoloured, stained, chipped, crooked, and misaligned teeth. If you’re dealing with minor teeth misalignment, then veneers can help create the appearance of straighter, <a href="https://oversixty.com.au/lifestyle/beauty-style/9-foods-to-avoid-to-keep-your-teeth-white" target="_blank" rel="noopener">brighter teeth</a> without the pain and discomfort of regular braces.</p> </div> </div> </div> <div title="Page 3"> <div> <div> <p>However, note that veneers are semi-permanent. Thus, you’ll need to replace them every 5-10 years, depending on your oral hygiene. Additionally, your dentist will need to buff away some of the enamel on the teeth’s surface to attach the veneers.</p> <p><strong>3. Dental Crowns </strong></p> <p><strong> </strong></p> <p>Dental crowns, also known as dental caps, are used to cover and reinforce a damaged tooth or set of teeth. In addition to protecting a severely decayed tooth after a root canal or filling, dental crowns can also be used to straighten your smile.</p> <p>In particular, crowns are useful when you need to change the colour, shape, or size of a tooth to match neighbouring teeth. You can choose crown materials that match your natural teeth as closely as possible. This creates the appearance of a straight and perfectly aligned smile. Dental crowns are also quite durable, allowing you to have a straighter smile for years to come.</p> <p><strong>4. Teeth-Straightening Surgery </strong></p> <p><strong> </strong></p> <p>If you have severely crooked teeth and you want a faster way to straighten them, then teeth- straightening surgery is your best option.</p> <p>For slightly crooked teeth, your orthodontist may suggest a minor surgical procedure to reposition your gums and bones to hold your teeth in place.</p> <p>However, for severely misaligned or crooked teeth that affect your chewing or speech, your dentist may recommend a more involved surgery designed to completely realign your jaw, also known as <a href="https://www.mayoclinic.org/tests-procedures/jaw-surgery/about/pac-20384990#:~:text=Jaw%20surgery%2C%20also%20known%20as,also%20improve%20your%20facial%20appearance." target="_blank" rel="noopener">orthognathic surgery</a>.</p> <p><strong>Takeaway </strong></p> <p>Having straight, perfectly aligned teeth not only gives you a charming and beautiful smile but also offers several health benefits, including a cleaner mouth and reduced risk of developing tartars and tooth decay.</p> <p>As you can see, you have various options to get your teeth realigned. However, the best procedure to straighten your teeth will depend on several factors, including your oral health history and the severity of the issue. In general, your dentist can help you decide on the best solution for your needs.</p> <p><em><strong>This is a sponsored article produced in partnership with <a href="https://www.ariadental.net.au/dental-articles/how-does-invisalign-work/" target="_blank" rel="noopener">Aria Dental</a>.</strong></em></p> </div> </div> </div>

4 habits that are surprisingly bad for your teeth

<p>While we’d never go weeks without taking a shower or eating, why is it that so many of us are guilty at neglecting our teeth every day? Just as much as taking care of your teeth is about keeping them clean and your breath fresh, it’s also about preventative maintenance.</p> <p>How many of these bad oral health habits are you guilty of? </p> <p><strong>Not visiting the dentist enough</strong></p> <p>Even if you think you go above and beyond when looking after your oral health – think brushing, flossing, and even use a special set of dental tools remove plaque – that still doesn’t mean you can skip your yearly cleaning at the dentist’s office.</p> <p>Make sure to schedule an appointment at least once a year.</p> <p><strong>Brushing from side to side</strong></p> <p>If you clean your teeth twice a day you deserve a pat on the back, right? Simply sticking a toothbrush in your mouth and moving it around is not enough. Good tooth brushing requires a certain technique. This does not involve any side-to-side action. Rather you’ll want to go in small circles. Forceful side-to-side brushing combined with an abrasive toothpaste can actually damage the teeth.</p> <p>You also need to ensure you brush along the gum line and the back of your teeth to loosen bacteria. Another big brushing mistake? Not doing it for long enough. While most people would’ve heard that the ideal length of time is two minutes, this is an arbitrary number, rather you should brush until you completely get all sides of every single tooth.</p> <p><strong>Using a non-fluoride toothpaste</strong></p> <p>Not all toothpastes are created equal! Some toothpastes, especially natural ones, brand themselves as fluoride-free, even though you need fluoride to achieve the healthiest mouth possible.</p> <p>Fluoride is essential because unless you remove absolutely every bit of plaque each day, fluoride can help replace the minerals worn away by bacteria-produced acid.</p> <p><strong>Chewing on ice</strong></p> <p>While chewing ice can be very refreshing, given that teeth don’t have great fracture resistance, it’s not a good habit to get in. Furthermore, as ice will take your mouth from warm to cold – and this tends to make things expand and contract very slightly – it can be enough to put little micro-cracks in your enamel.</p> <p>You can get away with it for a while, but the little cracks in your teeth can build up and one day, a piece might just break off.</p> <p><em>Image credits: Getty Images</em></p>

How to clean your dogs teeth

<h4>The importance of clean teeth</h4> <p>Good dental hygiene for dogs goes beyond improving pungent breath. About 80 percent of dogs develop dental disease by age four. That not only affects canine health but also leads to plenty of other problems down the road. And veterinary dentistry procedures hit you in the heart and the pocketbook. But learning how to clean dogs’ teeth isn’t typically the hottest topic in any pet care manual.</p> <p>Because dogs don’t open wide and say “ah,” veterinarians must use pricey anaesthesia to perform root canals, extract a tooth, or straighten crooked fangs. Pets almost never get cavities filled, though. Damaged or decayed teeth get removed, and plaque – it looks like yellow or brown deposits on the teeth and leads to tooth loss and pain – is cleaned away.</p> <p>You can reduce the frequency of required professional cleanings by learning how to clean dogs’ teeth at home. So grab a dog toothbrush, read the step-by-step instructions below, and get ready to brush your dog’s teeth daily.</p> <h4>How to clean your dogs teeth</h4> <p>Cleaning your dog’s teeth is a part of dog grooming and is just as important as giving your dog a bath. You already know how to brush your own teeth, and the same technique applies to cleaning your dog’s teeth.</p> <p>But your dog won’t willingly open wide for you. So part of cleaning its teeth includes teaching it what to expect so it won’t feel scared. Training your dog to accept teeth cleaning keeps it healthy and can also improve the bond you share with each other.</p> <p>Teaching your dog takes time. Don’t rush or force your pet. It may take three days or three weeks before your pup is ready to let you clean its teeth. But once it understands and accepts the procedure, the teeth cleaning won’t take more than a few minutes a day. Ideally, you’ll want to clean your dog’s teeth after each meal, just like humans do. But if you can manage once a day, or even two or three times a week, count that as a win.</p> <h4><strong>Supplies</strong></h4> <p>Chew toy: Dogs love to chew anyway, but a favourite toy helps with training. Choose a non-fabric toy that won’t hold moisture. Something your dog likes to hold or carry gets bonus points. A dental toy for big dogs, or one sized for smaller dogs, is ideal.</p> <p>Dental treats: Use dental treats along with the toy to teach your dog to accept holding something in its mouth. The treats reward the behaviour you want your pet to learn, so it trusts that even if you ask it to do something weird, it’ll get good things out of it.</p> <p>Bath towel: No, you won’t dry him off with the towel. But toothbrushing can involve drooling and head-shaking that leads to dribbled toothpaste. A towel provides an easy-to-clean surface for training and eventual teeth cleaning. Using the same towel each time signals to your dog what happens next.</p> <p>Dog toothpaste: Never use human toothpaste with your dog. Dogs can’t spit and shouldn’t swallow the fluoride that human products contain. Dogs also hate the foaming action. Instead, choose a toothpaste designed specifically for dogs. Pet toothpaste contains flavours dogs love, like peanut butter.</p> <p>Gauze pads: You don’t have to use a toothbrush, and dogs may accept other materials more readily. Gauze pads work well and are disposable. They also work as a first step. Once your pup accepts cleanings with gauze, you can move on to other cleaning options.</p> <p>Wipe: A washcloth also works to clean dog teeth. Simply wrap it around your index finger and apply the paste. As an added bonus, you have a towel handy if you need to wipe off your dog’s face. Another option is using dental wipes for dogs.</p> <p>Finger toothbrush: Dogs are funny. They’ll pick up nearly anything in their mouths but object to you sticking something weird inside. Yours may more easily accept a finger – or a finger toothbrush. You might find it easier to use too.</p> <p>Baby toothbrush: Baby’s first toothbrush, with its extra-oft bristles, may work for some dogs, especially those with tiny mouths.</p> <p>Dog toothbrush: If you like, you can work up to using an official dog-specific toothbrush.</p> <p>Dental rinse: There are products you can use to rinse off your dog’s teeth, as well as those you can add to your dog’s water, to help keep its teeth clean.</p> <p>Ready to get brushing?

The steps below will guide you from training to regular brushings.</p> <h4>1. Gather Supplies</h4> <p>Bring everything you plan to use to the location you’ll be cleaning your dog’s teeth. You may want to keep teeth-cleaning tools in the same place as your other grooming supplies. Your pup should eventually enjoy the experience and expect the event. To speed up the process, choose somewhere your dog already associates with fun times or yummy rewards, like in the kitchen near the food bowl.</p> <p>And think about a convenient schedule. Dogs love routine, so cleaning your pet’s teeth in the same location and at the same time can help your furry friend view teeth cleaning as part of a normal day.</p> <h4>2. Touch your dogs mouth</h4> <p>Have a small dog? Spread the towel on your lap so your pet can sit during the cleaning. For big dogs, lay the towel on the floor and kneel next to your pup. The towel becomes your dog’s cue that it’s teeth-cleaning time.</p> <p>Start with petting your pup, paying particular attention to the outside of its mouth and lips. If it’ll allow it and you feel comfortable, let it mouth your fingers. Even better, slip a finger inside its cheek to stroke the sides of its teeth. It doesn’t need to open its jaws at all. Its tongue keeps the inside surface of its teeth clean, so you only need to take care of the outside surface. Do this for five minutes and offer a treat each time your dog lets you stroke its gums or touch a tooth.</p> <p>Repeat this step once or twice a day for three to five days. After the dog accepts your handling of its mouth, move to the next step.</p> <h4>3. Flavour the toy</h4> <p><span style="color: #444444; font-family: Raleway, sans-serif, 'Helvetica Neue', Helvetica, Arial; font-size: 16px; background-color: #ffffff;">Spread dog toothpaste on a non-fabric toy and let your pet lick it off. Many dogs enjoy the paste-like treat. It has ingredients that help clean teeth even without brushing, so that’s a great first step. You want to associate the toy with the yummy flavour.</span></p> <h4>4. Prop open the dogs mouth</h4> <p>If your dog wants to take the toy into its mouth, let it. But use your hand to hold its mouth closed around the toy. That way, the flavoured toy it holds and enjoys also props open its jaws just enough for you to clean its teeth. Spend about five minutes playing with the toy, taking it from your dog to add paste, and then letting your dog hold the toy while you grasp its muzzle. Repeat this step once or twice a day for several days in a row.</p> <p>Don’t let your dog swipe the toy away to chew. Reserve this special toy for teeth cleaning so your pet only gets the yummy paste and other treats for this purpose. When it acts excited at the sight of the towel, toy and paste, move on to the next step.</p> <h4>5. Prep the applicator </h4> <p>Whether you’re using a finger toothbrush, gauze pad or a washcloth, you’ll want to spread dog toothpaste onto the brushing material. You won’t need a lot of paste, so just add enough to cover the end of your finger.</p> <h4>6. Clean teeth on one side</h4> <p>With one hand wrapped around your dog’s muzzle as it holds the toothpaste-coated toy, use the toothpaste-covered applicator to wipe the outside of its teeth on one side of its mouth. Do the top jaw first, and if your dog is still fine with it, finish with the bottom teeth on the same side. You don’t need to scrub – simply wipe the paste from side to side.</p> <p>Release its muzzle and remove the toy. The dog will lick its lips and savour the paste you’ve left on its teeth. Quit for the day, after offering your pup a few more treats for being such a good dog.</p> <h4>7. Clean teeth on the other side </h4> <p>The next day, repeat the previous step. This time, you’ll wipe the teeth on the other side of your dog’s mouth. Remember, there’s no need to clean the inside of the teeth since the dog’s tongue keeps those surfaces clean.</p> <p>Poking inside its mouth also risks an accidental bite should his jaws slip off the toy. Just wipe the outside of the teeth.</p> <p>Always quit before your dog asks you to stop; it’ll leave your pup wanting more. Praise and treat generously.</p> <h4>8. Make sure every tooth is clean</h4> <p>After two or three days of one-sided teeth cleanings, your dog should understand the process. Hopefully, it also looks forward to this teeth-cleaning routine. Now it’s time to graduate to cleaning all of the teeth at once. This shouldn’t take more than five minutes, including preparation time. If possible, brush daily.</p> <h4>9. Add a dental rinse</h4> <p>In between brushes, you can add a dental rinse to your dog’s drinking water. This will keep its mouth fresh and help improve its overall dental hygiene.</p> <p>This article originally appeared on <a href="https://www.readersdigest.com.au/food-home-garden/pets/how-to-clean-your-dogs-teeth" target="_blank" rel="noopener">Reader's Digest</a>. </p> <p><em>Image: Getty</em></p>

Prince Charles is "immensely sensitive" and ignoring Prince Harry

<p>Princess Diana's former voice coach, Stewart Pearce, has claimed the reason Prince Charles has had a hard time with Prince Harry's parenting criticisms is that Prince Charles is "immensely sensitive".</p> <p>Pearce revealed to US Weekly that the future king of England is a "very very shy man".</p> <p>“Prince Charles is a very, very shy man, a very sensitive and delicate man, but we see his public personality, but in private, he’s immensely sensitive,” he said.</p> <p>“When we’re sensitive, if we’re dealing with very strong, combustible emotion on the outside of us,” people tend to go into fight or flight.</p> <p>For example, when Princess Diana accused him of having an affair with Camilla Parker Bowles, “what he did was to shrink back and as a result of that became aloof,” Pearce explained. “Well, that doesn’t heal the challenge that’s taking place.”</p> <p>Pearce said that when reports broke about Prince Harry and Meghan being "troubled" by the 'lapse of contact", Pearce wasn't surprised as "that's what Charles does".</p> <p>“He can’t deal with it because of his sensitivity, so he hides. And what Harry’s trying to do is to heal that. Not out of umbrage, not out of anger or revenge or criticism or accusation…I felt that he was just somebody saying, ‘This is the way that it is, and this is why we want to make change.’”</p> <p>The comments that Pearce is referring to were made by Prince Harry on his Apple TV+ series with Oprah The Me You Can't See.</p> <p>“My father used to say to me when I was younger, he used to say to [Prince] William and I, ‘Well, it was like that for me, so it’s gonna be like that for you.’" he said.</p> <blockquote style="background: #FFF; border: 0; border-radius: 3px; box-shadow: 0 0 1px 0 rgba(0,0,0,0.5),0 1px 10px 0 rgba(0,0,0,0.15); margin: 1px; max-width: 540px; min-width: 326px; padding: 0; width: calc(100% - 2px);" class="instagram-media" data-instgrm-permalink="https://www.instagram.com/p/B2bL_xMgwoL/?utm_source=ig_embed&amp;utm_campaign=loading" data-instgrm-version="13"> <div style="padding: 16px;"> <div style="display: flex; flex-direction: row; align-items: center;"> <div style="background-color: #f4f4f4; border-radius: 50%; flex-grow: 0; height: 40px; margin-right: 14px; width: 40px;"></div> <div style="display: flex; flex-direction: column; flex-grow: 1; justify-content: center;"> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; margin-bottom: 6px; width: 100px;"></div> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; width: 60px;"></div> </div> </div> <div style="padding: 19% 0;"></div> <div style="display: block; height: 50px; margin: 0 auto 12px; width: 50px;"></div> <div style="padding-top: 8px;"> <div style="color: #3897f0; font-family: Arial,sans-serif; font-size: 14px; font-style: normal; font-weight: 550; line-height: 18px;">View this post on Instagram</div> </div> <p style="color: #c9c8cd; font-family: Arial,sans-serif; font-size: 14px; line-height: 17px; margin-bottom: 0; margin-top: 8px; overflow: hidden; padding: 8px 0 7px; text-align: center; text-overflow: ellipsis; white-space: nowrap;"><a style="color: #c9c8cd; font-family: Arial,sans-serif; font-size: 14px; font-style: normal; font-weight: normal; line-height: 17px; text-decoration: none;" rel="noopener" href="https://www.instagram.com/p/B2bL_xMgwoL/?utm_source=ig_embed&amp;utm_campaign=loading" target="_blank">A post shared by Clarence House (@clarencehouse)</a></p> </div> </blockquote> <p>"That doesn’t make sense. Just because you suffered, it doesn’t mean that your kids have to suffer. In fact, quite the opposite. If you suffered, do everything you can to make sure that whatever experiences, negative experiences that you had, you can make it right for your kids.”</p> <p>The conversation was said to leave Prince Charles "quite devastated" according to an insider who told <a href="https://www.vanityfair.com/style/2021/05/all-charles-has-wanted-is-for-harry-to-be-happy-can-this-father-son-relationship-ever-heal"><em>Vanity Fair.</em></a></p> <p>“He is such a gentle man and a dedicated father first and foremost. Knowing him, he’ll be feeling wretched and will take no joy or happiness in what’s going on within the family. But he will also want to seek a reconciliation. He is not vindictive at all, and he wants to make peace with Harry.”</p>

Thank Neanderthals’ diet for your big brain

Sore jaw or damaged teeth? You might be suffering from bruxism

<p><span style="font-weight: 400;">If you’re feeling stressed, you might notice you’re snappier with people or having trouble getting enough sleep. </span></p> <p><span style="font-weight: 400;">But, one area of the body that is greatly affected but seldom talked about when it comes to stress can be found in your mouth.</span></p> <p><span style="font-weight: 400;">Teeth grinding - also known as bruxism - can occur in almost anyone and result in broken fillings and cracked teeth.</span></p> <p><span style="font-weight: 400;">Before you get too worried about your oral health, you should know that everyone grinds their teeth at least a little bit.</span></p> <p><span style="font-weight: 400;">“Everybody grinds their teeth a little bit at night, it’s normal and we do it subconsciously - usually during dream sleep,” Dr Tami Yap, a lecturer in oral medicine at Melbourne University, told </span><span style="font-weight: 400;">The Age</span><span style="font-weight: 400;">. </span></p> <p><span style="font-weight: 400;">“If sleep is fragmented, you’re not getting solid sleep cycles, or you have a period of stress where you mood is impacted into the night-time, you will probably grind more.”</span></p> <p><span style="font-weight: 400;">The problems arise when grinding causes the teeth to become worn down or break, or if it causes the muscles in your face to ache.</span></p> <p><span style="font-weight: 400;">Additional symptoms can vary, from temperature sensitivity or a sore jaw to tension headaches or pieces of your teeth breaking off in your mouth.</span></p> <p><span style="font-weight: 400;">Though there isn’t a simple way to “switch off” tooth grinding, Yap explained, there are some things you can do to manage it.</span></p> <p><strong>What makes us grind our teeth?</strong></p> <p><span style="font-weight: 400;">According to Dr Elizabeth Milford, a dentist and scientific relations consultant for Oral-B, tooth grinding can be triggered by increased anxiety, not getting enough exercise, and poor sleep habits.</span></p> <p><span style="font-weight: 400;">Other habits can also exacerbate night-time tooth grinding, such as smoking, drinking large amounts of alcohol, and taking recreational drugs. But these habits are more influential on how much we grind our teeth during the day.</span></p> <p><span style="font-weight: 400;">Daytime tooth grinding is often triggered by our mood, habits, and stress levels.</span></p> <p><span style="font-weight: 400;">“When we are worried or highly stressed, we are physiologically perceiving a low-grade threat,” Yap explained. “And when this happens, stress hormones run around the body and the sympathetic system is engaged because the body is prioritising you to fight or flight.”</span></p> <p><span style="font-weight: 400;">With this comes extra tension in your muscles, with people often holding their teeth together like you would clench your fist.</span></p> <p><span style="font-weight: 400;">“And if you were clenching your fist, it would be very clear you shouldn’t be doing that. Similarly, if you’re touching your teeth together at times other than eating, you’re going to be loading your teeth more, and you’re going to get cracks, and possibly muscle pain.” </span></p> <p><strong>What can you do about it?</strong></p> <p><span style="font-weight: 400;">Minimising tooth grinding requires a holistic approach. Consciously choosing the position of your mouth and jaw and thinking about what our facial muscles are doing can help reduce it.</span></p> <p><span style="font-weight: 400;">“Teeth should only be touching when you’re eating, maybe when you phonate certain words and sometimes when you swallow,” Dr Yap said. “That amounts to a few minutes a day, the rest of the time the teeth should actually be apart.”</span></p> <p><span style="font-weight: 400;">Dr Yap recommends focusing on breathing, since this helps you become “more aware of how your mood and your stress is impacting changes on your body”.</span></p> <p><span style="font-weight: 400;">Treatment can also include jaw exercises, relaxation techniques, and custom-made dental appliances that reduce pressure on teeth.</span></p> <p><span style="font-weight: 400;">Dentists often recommend night guards, but becoming more aware of how we’re feeling and how our body is reacting will pay off in the long run.</span></p>
