Could a Night Guard Be the Answer to Your Dreams?

August 19th, 2025

Have you been having trouble getting a good night’s rest?

Sometimes the reason for a poor night’s sleep is obvious. A midnight horror movie. A bedtime espresso. That anchovy and pineapple pizza you had for dinner. Not much we can do about these problems.

Sometimes, though, the cause of your sleep difficulties is dental in origin, and that is something Dr. Cosman, Dr. McDonough, Dr. Levac and Dr. Korcok can help with.

Teeth grinding, or bruxism, is a very common dental problem. When people with this condition sleep, their jaws clench and their teeth grind against each other throughout the night. When to suspect you might suffer from bruxism?

  • You wake with a sore jaw, or you hear pops or clicks when you move your jaw
  • You suffer from frequent headaches or facial pain
  • Your teeth are chipped, cracked, flattened, worn down, or sensitive
  • You wake up tired, because grinding affects the quality of your sleep
  • Partners, siblings, or roommates complain about nocturnal grinding noises affecting the quality of their

Pain and fatigue are unpleasant enough, but there are additional serious consequences for those who suffer from bruxism. Our jaws are extremely powerful, and clenching and grinding can put hundreds of pounds on pressure on teeth and jaws over hours of sleep. These forces can lead to:

  • Damaged teeth. Cracked, chipped, and worn down teeth can mean veneers, crowns, and root canals. Seriously compromised or broken teeth might need to be extracted.
  • Damaged dental work. Bruxism can lead to fractured veneers and damaged fillings and crowns. If the damage is too serious for repair, replacement might be necessary.
  • Damaged jaw joints. Severe cases of bruxism can lead to injury to the temporomandibular joint, or TMJ, the complex hinge that allows our jaws to move up and down, back and forth, and side to side.

While these problems can be treated with restorations, or root canals, or implants, or surgical procedures, prevention is clearly a much better option for a healthy smile. And one of the simplest and most effective treatments for preventing the damage caused by bruxism is a night guard.

Night guards fit over the affected teeth to prevent them from touching directly, saving tooth and enamel from injury and wear. Not only do night guards prevent contact, they spread the biting forces of the jaw over the surface of the guard to greatly reduce their impact. And because they also stop the jaw muscles from clenching tightly, there’s no excess stress placed on the temporomandibular joint.

While over-the-counter products are available, it’s best to see Dr. Cosman, Dr. McDonough, Dr. Levac and Dr. Korcok for the most effective night guard. A custom night guard is designed to fit your individual teeth and mouth perfectly. Impressions or 3D scans are taken in our Kingston, ON office, and a guard is fabricated with the precise shape, strength, and thickness you need to protect your teeth. And, as a bonus, custom night guards offer the most comfortable fit for the most comfortable night’s sleep.

Scary movies, late night caffeinating, creative food combinations—not much we can do about those! But if you’re suffering lost sleep and painful mornings because of tooth grinding, give us a call. A night guard just might be the key to sweet dreams.

Curing the Nail-Biting Habit

August 13th, 2025

Do you ever find yourself gnawing at your nails? Nail-biting is a very common and difficult to break habit which usually has its beginnings in childhood. It can leave your fingers and nail beds red and swollen. But if you think that your nails are the only ones getting roughed up by nail-biting you'd be mistaken—so are your teeth!

According to a study by the Academy of General Dentistry, those who bite their nails, clench their teeth, or chew on pencils are at much higher risk to develop bruxism (unintentional grinding of the teeth). Bruxism can lead to tooth sensitivity, tooth loss, receding gums, headaches, and general facial pain.

Those are some nasty sounding side effects from chewing on your nails. Most nail-biting is a sign of stress or anxiety and its something you should deal with. So what steps can you take if you have a nail-biting habit?

There are several things you can do to ease up on nail-biting:

  • Trim your nails shorter and/or get regular manicures – Trimming your nails shorter is an effective remedy. In so doing, they'll be less tempting and more difficult to bite on. If you also get regular manicures, you’ll be less likely to ruin the investment you’ve made in your hands and fingernails!
  • Find a different kind of stress reduction – Try meditation, deep breathing, practicing qigong or yoga, or doing something that will keep your hands occupied like squeezing a stress ball or playing with a yo-yo.
  • Wear a bitter-tasting nail polish – When your nails taste awful, you won't bite them! Clear or colored, it doesn't matter. This is also a helpful technique for helping children get over the habit.
  • Figure out what triggers your nail-biting – Sometimes it's triggered by stress or anxiety and other times it can be a physical stressor, like having hang nails. Knowing what situations cause you to bite your nails will help you to avoid them and break the habit.
  • Wear gloves or bandages on your fingers – If you've tried the steps above and they aren't working, this technique can prove effective since your fingernails won't be accessible to bite.

If you're still having trouble with nail-biting after trying these self-help steps, it's best to consult your doctor, dermatologist, or Dr. Cosman, Dr. McDonough, Dr. Levac and Dr. Korcok. For some, it may also be the sign of a deeper psychological or emotional problem.

Whatever the cause, nail-biting is a habit you need to break for your physical and emotional well-being. If you have any questions about the effects it can have on your oral health, please don't hesitate to ask Dr. Cosman, Dr. McDonough, Dr. Levac and Dr. Korcok during your next visit to our Kingston, ON office.

Dental Adulting

August 12th, 2025

Now that you’re entering the working world, or heading off to college, or pursuing any of the many adventures awaiting you in adult life, you’re ready to take on more adult responsibilities. And one of those responsibilities is making sure you maintain your dental health.  

Luckily, it’s not that hard! Successful adulting often means simply making small proactive choices which add up to big long-term benefits. So, let’s look at a few of the everyday habits of dentally successful adults.

Choose a Healthy Lifestyle

  • Eat well.

Just like the rest of our bodies, our teeth and gums need a healthy diet to thrive. Sugar-fueled study sessions and energy drink-filled work hours should be the rare exception, not the norm. A diet rich in vitamins and minerals keeps gums healthy and enamel strong.

  • Don’t use tobacco products. 

Cigarettes, cigars, pipe smoking, chewing tobacco—any form of tobacco products, especially combined with alcohol use, can greatly increase your chances of developing mouth and throat cancers.

  • Talk to your doctor about the HPV vaccine.

HPV (human papillomavirus) can also cause mouth and throat cancers. The American Academy of Pediatrics recommends the HPV vaccine for kids ages 9 through 12. If you haven’t been vaccinated yet, talk to Dr. Cosman, Dr. McDonough, Dr. Levac and Dr. Korcok about the potential benefits of the HPV vaccine. 

Keep Up with Your Orthodontic Care

If you’ve spent several of your teen years in braces or aligners creating a beautiful, healthy smile, you don’t want to see all your hard work go to waste. Retainers are designed to make sure your teeth stay just where they belong for a lifetime. 

When retainers aren’t worn as directed, especially when braces or aligners first come off, the teeth can shift back to their old positions. Sometimes going back to your regular retainer schedule can fix any minor movement, but sometimes patients need to go back for repeat orthodontic treatment.

How to avoid orthodontic do-overs?

    • If you have a retainer, wear it as scheduled to maintain your alignment and healthy bite. 
    • Put your retainer in a case when you’re not wearing it. A bent or broken retainer won’t keep your teeth aligned properly and can damage delicate oral tissues!
    • If your retainer is damaged, see the dental team at Cataraqui Dental Centre in Kingston, ON ASAP for repair or replacement.

 Practice Good Oral Hygiene

  • Brush at least twice a day, for two minutes each time. 

Plaque begins to build up within hours after your last brushing. Removing plaque morning and evening also removes the cavity-causing bacteria which live in plaque. These bacteria erode enamel and lead to cavities.

  • Floss at least once a day. 

Flossing helps remove plaque from your gumline. When plaque accumulates over time, it becomes tartar, a substance so hard that you’ll need a dental professional to remove it. The bacteria in plaque and tartar irritate your gums, and this irritation is the beginning of gum disease. Early stage gum disease (gingivitis) can often be reversed with better brushing and flossing habits—but, even better, help stop gum disease before it starts with daily flossing.

  • See your dentist regularly. 

If you’ve been seeing your pediatric dentist since early childhood, you’ve probably developed a great partnership. You know that a visit twice each year, or as recommended, for an exam and a professional cleaning will make sure your smile stays its healthy, sparkling best. 

And now that you’re entering adulthood, it might be time to make a transition to your adult dental team. Some pediatric dentists suggest that patients transition to a new dentist around the age of 18, while others treat young patients through early adulthood. Talk to your dentist about how to graduate most easily and comfortably to a new dental team for your adult years—and then make regular checkups and cleanings with your new dentist a priority.

Not so difficult, right? In fact, you’ve probably adopted most of these healthy habits already. Take charge of your dental health now, make good habits a part of your daily routine, and you’ll be prepared to enjoy a lifetime of healthy, attractive, adult smiles!

 

Why Do Molars Seem to Get More Cavities?

August 6th, 2025

Probably because, for many kids, molars do get more cavities. So let’s answer two better questions: Why do molars get more cavities? And, how can we help prevent them?

It’s the Pits. (And Fissures.)

The reason molars are so useful—and more likely to develop cavities—is because of their shape. Unlike our front teeth, which are used to bite through foods, molars are used to grind and chew. That’s why they are so much larger, with a flat surface on top. Well, not exactly flat.

When you look at a molar, you’ll notice that the top isn’t really smooth at all. It’s covered with little indentations known as pits and longer grooves called fissures. These irregular features both trap food particles and make it more difficult for bristles to clean them away. Cavities in molar surfaces are so common that they even have a specific name: “pit and fissure cavities.”

But molar biology does not mean tooth decay is inevitable! There are steps you can take to protect your children’s molars as they grow, while you’re providing them with dental strategies that will keep their adult molars healthy and cavity-free.

Preventing Pit and Fissure Cavities

  • Don’t Just Brush—Brush Effectively

The first step in preventing any kind of cavity is brushing properly. Your child should be brushing at least two minutes, at least twice each day. And while the time we spend brushing is important, technique is also key.

When you’re showing your child how to brush, be sure that the tops of molars, upper and lower, get brushed thoroughly, with special emphasis on cleaning pits and fissures. Make sure the toothbrush is small enough to fit your child’s mouth comfortably and reach all the tooth surfaces. Replace worn-down brushes or electric toothbrush heads after three to four months when they no longer clean as effectively.

Your child will probably need adult supervision from toddler years through the early years of grade school to learn how to brush properly. This is time well spent, as your child learns cavity-preventing brushing techniques which will last a lifetime.

  • Eat a Tooth-Healthy Diet

Plaque bacteria use the sugars in our food to make acids. These acids break down the mineral strength of tooth enamel and eventually lead to cavities. And because pits and fissures are great hiding places for bacteria and food particles (especially sticky ones), molars are even more at risk for cavities. Limiting sugary, sticky foods like sweet treats and simple carbs helps reduce that risk.

Acidic foods like flavored juices, sour candies, sodas, and power drinks also weaken enamel and can leave teeth more vulnerable to decay. Help your child avoid cavities by limiting acidic foods and drinks, making them part of a balanced meal, and/or rinsing with water after eating.

  • Use Fluoride Toothpaste

Fluoride toothpaste not only reduces the risk of cavities, it also helps strengthen enamel that has been weakened by bacterial and dietary acids. Win-win!

  • Ask About Sealants

Sealants are invisible, safe coatings which protect molars by preventing food and bacteria from getting trapped in their uneven surfaces. The top of the molar is first treated with an etching solution to allow the sealant to bond tightly to the tooth, a thin coat of sealant is painted on, and then it’s hardened under a curing light. That’s all there is to it.

Sealants are often recommended when children’s permanent molars first erupt, when they are especially at risk for cavities. Sealants can last from three to five years (or even longer), and studies have shown a dramatic reduction in cavities for patients who use sealants compared to patients with untreated teeth. Depending on your child’s individual needs, Dr. Cosman, Dr. McDonough, Dr. Levac and Dr. Korcok might recommend a sealant for baby molars as well.

  • Regular Exams and Cleanings

It might be hard for you to tell if your child’s molars have been affected by sticky plaque, or sugary foods, or acidic drinks, or inadequate brushing, or any other potential cavity-causers. It’s not a difficult job for Dr. Cosman, Dr. McDonough, Dr. Levac and Dr. Korcok, though! Through regular checkups and cleanings at our Kingston, ON office, we will discover any conditions that might lead to cavities, and, if necessary, treat small cavities before they lead to more serious decay.

Statistically, childhood molars have a greater chance of developing cavities than incisors and canines. Help your child beat the odds by understanding why these teeth are at risk and by working with your dental team to give your child years of healthy teeth now and a future filled with beautiful smiles!
