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!

Dangers of Alcohol and Oral Health

August 5th, 2025

We often have patients who ask, “Can drinking alcohol affect my oral health?” There are, in fact, a few reasons why that martini may not be good for your pearly whites.

In addition to creating an overly acidic environment in your mouth, alcohol severely dehydrates oral tissues because of its desiccant and diuretic properties. Because alcohol saps oral tissues of their moisture so readily, saliva glands can't keep enough saliva in the mouth to prevent dry mouth. In addition, saliva contains antibacterial properties that inhibits growth of anaerobic bacteria, a destructive type of oral bacterial responsible for tooth decay, gingivitis, chronic bad breath, and periodontitis.

What are anaerobic bacteria?

When there is a lack of saliva flow in the mouth and the mouth cannot naturally cleanse itself of oral debris (food particles, dead skin cell, mucous), conditions develop that promote activity of anaerobic bacteria, or bacteria that thrive in dry, airless places. These anaerobes also flourish when an unending supply of proteins (food debris) are available to consume, creating rapidly multiplying layers of plaque that stick to teeth and demineralizes tooth enamel unless removed by brushing and professional dental cleanings.

Oral Cancer and Alcohol

Acetaldehyde is a chemical compound leftover after the liver has metabolized alcohol. Capable of causing genetic mutations, acetaldehyde is also a known carcinogen that contributes to the ill feelings of hangovers. Although most metabolism of alcohol is done in the liver, evidence shows that metabolism also occurs outside the liver and that enzymes in the mouth could encourage accumulation of acetaldehyde in oral tissues.

When combined with poor oral health, smoking, and other detrimental lifestyle factors, alcohol may be considered a primary contributory factor in the development of oral cancer.

Even if you don't drink or drink only occasionally, remaining aware of symptoms that may indicate oral cancer will improve your chances of recovering successfully when you start treatment in the early stages of oral cancer. Signs include red or while speckled patches in the mouth, unexplained bleeding, lumps/swellings, chronic ear or throat pain, and areas of numbness in the mouth or on the face.

If you have any questions about alcohol and its connection to oral health, don’t hesitate to ask Dr. Cosman, Dr. McDonough, Dr. Levac and Dr. Korcok at your next visit to our Kingston, ON office.
