Root Cavities

April 9th, 2025

When we don’t keep up with our dental hygiene, plaque buildup can result in three kinds of cavities. Pit and fissure cavities are found on the tops of molars, where food particles get stuck in the irregular surfaces. Smooth surface cavities are located on the smooth sides of teeth.

Wait. Top, all around the sides—what’s left for plaque to attack?

Our roots. The roots of our teeth are generally protected by their concealed position in the jaw. Sitting securely in alveolar bone, held firmly in place by connective tissue, with gum tissue snugly surrounding them, roots are generally not cavity prone.

But these cozy conditions can change. Due to gum disease, abrasive habits, or simply the passage of time, gums can recede and expose root surfaces. And this exposure can lead to root cavities.

If you look at a complete tooth, it looks like enamel is covering the entire tooth surface. In fact, enamel, the strongest substance in the body, only covers the visible part of the tooth, called the crown. The roots are covered by a substance called cementum, which is softer than enamel. And if enamel can’t stop decay, cementum is even more vulnerable when it’s exposed to plaque, bacteria, and acidic foods.

How do we protect our roots from decay? Protecting our gums is the first line of defense.

  • Gum Disease

Receding gums caused by periodontitis can be treated by Dr. Cosman, Dr. McDonough, Dr. Levac and Dr. Korcok. Deep cleaning procedures such as scaling and root planing can remove accumulated plaque and tartar, and help gum tissue reattach to teeth. For serious recession, gum grafts can replace lost tissue.

Early treatment can prevent recession. If you notice any signs of early gum disease, including bleeding, swelling, tenderness, or persistent bad breath, it’s time for a visit to our Kingston, ON office.

  • Gum Abrasion

It’s not just gum disease that can lead to gum recession. Some personal habits are hard on gums and teeth, and can leave roots exposed. If you bite your nails, grind your teeth, irritate your gums with oral piercings, you are at risk for gum recession. Talk to Dr. Cosman, Dr. McDonough, Dr. Levac and Dr. Korcok about preventing abrasive damage.

A surprising cause of receding gums? Over-vigorous brushing. Use a soft-bristled brush—and don’t use a heavy hand when brushing—to protect your delicate gum tissue.

  • Aging

As we age, our gums recede. So it’s no wonder that older adults are especially at risk for root cavities. That’s why it’s very important to keep up with brushing (at least two minutes twice a day) and flossing (once a day, or more often if needed) to prevent the buildup of plaque and tartar.

And it’s more important than ever to schedule regular dental exams and cleanings. Dr. Cosman, Dr. McDonough, Dr. Levac and Dr. Korcok can help stop small problems from becoming major ones, and suggest brushing and flossing techniques, fluoride treatments, or other procedures to encourage gum and dental health.

If a cavity develops, no matter what kind, it should be treated as soon as possible. And time is especially important for a root cavity.

Because cementum is weaker than enamel, cavities can progress more quickly in roots. A cavity which has reached pulp tissue might require a root canal and a crown to restore tooth function. Serious decay could lead to extraction.

Don’t let root cavities undermine your dental health. If you notice any sign of gum disease or recession, it’s time for a visit to our Kingston, ON office. After all, even though they go unnoticed, strong roots are the foundation of a healthy, attractive, life-long smile.

Take Your Pick!

April 8th, 2025

Before electric toothbrushes, before dental floss, before fluoride rinses, in fact, before recorded history, people who cared about their dental health had one primary tool—the toothpick. Ancient bronze toothpicks, bejeweled Renaissance picks, and the more humble modern wooden picks have been instrumental in promoting dental hygiene for centuries.

And, while that clean, simple design is still a good one, modern technology has found a way to build an even better toothpick. Today’s interdental picks not only dislodge food particles effectively, but now gum stimulation, cleaner orthodontic appliances, and fresher breath are available literally at our fingertips. Most important, these picks are just as effective as floss for removing plaque.

  • Wood? Still Good!

Today’s softer wooden picks come in several shapes designed to fit comfortably and snugly between the teeth. Using a gentle in-and-out motion, you can clean between your teeth as you remove plaque from the tooth surface. But that’s not the only benefit! As you move the wide end of the pick up and down between teeth and gums, you are actually stimulating your gum tissue as well.  They even come with mint flavoring to refresh your mouth as you clean. And, of course, wood and bamboo picks are biodegradable.

  • Plastic? Fantastic!

If you’d like something a little more yielding than wooden dental picks, you have options. Soft dental picks are available that use rubber “bristles” on a plastic stem to gently ease their way between teeth. The heads are available in different diameters to accommodate tight or wide spacing between the teeth. Straight or curved stems provide the accessibility you need. If you have latex allergies, be sure to choose a rubber product that is latex-free.

  • Interproximal Brushes? Here’s What the Buzz Is

You might have missed these miniature brushes in the dental care aisle, but they are worth looking for. Interproximal brushes have small cone-shaped heads with nylon bristles for cleaning food particles and plaque from between the teeth. They are good for more than one use, and some are available with angled or bendable handles for hard-to-reach spots. They come in different diameters, from wide to extremely fine, to suit the spacing of your teeth. Interdental brushes are especially useful for braces wearers, who can use these clever tools to clean tight, tricky areas under wires and around brackets.

Even though bronze, bejeweled, or golden toothpicks aren’t available in the dental aisle of the local drugstore, increased efficiency and function are well worth the trade-off. If for any reason you have trouble flossing, or if you like the idea of massaging your gums as you clean your teeth, or if you wear braces, or if you want a burst of mint flavor—for any number of reasons today’s dental picks are worth a try. Talk to Dr. Cosman, Dr. McDonough, Dr. Levac and Dr. Korcok at your next visit to our Kingston, ON office, and we’ll be happy to give you some recommendations. 

Is There an Act Three for Our Teeth?

April 2nd, 2025

Act One: Those 20 adorable baby teeth which begin arriving when you’re about six months old and are probably gone by the time you’re twelve.

Act Two: The 32 (if you have all your wisdom teeth!) adult teeth which start showing up around the age of six, and need to last the rest of your lifetime. Unless there’s an . . .

Act Three: Where science has discovered a way to repair damaged teeth or create replacements for lost teeth that would look and function just like our original teeth.

Sounds like science fiction, doesn’t it?

In biological terms, of course, we’re not there yet. But teams of scientists around the world have been working toward just this goal—the ability to repair a tooth with its own biological material or even grow a new tooth when an adult tooth is seriously damaged or lost.

Because the pulp—the living tissue inside each tooth—contains dental stem cells, some researchers are studying whether these cells can be used to regenerate the living pulp inside a damaged tooth. Even more exciting, there’s research being done into the possibility of using these stem cells to rebuild an entire tooth—pulp, dentin, and hard enamel exterior. Because the supply of usable dental stem calls is quite small, and process of guiding these cells to create all the varied parts of the tooth is quite complex, this research is in its early stages.

In other studies, scientists have focused on tooth regeneration by studying the teeth of other species. Mice, for example, have front teeth with open roots. This allows these teeth to keep growing up as they wear down, because stem cells inside mouse gums are always working to create new tissue. Even though our teeth are not exactly comparable (no open roots in human teeth!), finding out just how this tissue regeneration works in mice and other animals might help find an answer for human tooth regeneration.

Right now, these scientific goals are just that—goals for a future day. But in the meantime, your quality of life doesn’t need to suffer when you lose an adult tooth. You can enjoy a third act right now with dental implants.

Cosmetic concerns aren’t the only reasons why you want your complete smile restored in the event of a lost tooth. A missing tooth can lead to many unpleasant consequences:

  • Speaking and eating can become more difficult.
  • Lack of stimulation from biting and chewing can cause the bone beneath the lost tooth to shrink.
  • Other teeth can shift to fill the gap left behind, which can affect tooth, bite, and jaw alignment.
  • Loss of teeth can lead to loss of confidence.

Unlike dentures or bridges, dental implants are designed to function just like your natural teeth.

The post, or base, of each implant fuses with the bone in your jaw, acting as a “root” for the implant. Once the post has fused with the bone around it, a crown designed to match your other teeth in shape and color is secured to the post. You can eat, speak, brush, floss, keep your bone healthy, and smile confidently just as you did before.

Will biological replacements be ready for your third act in the near future? Probably not. But that’s not to say this will never be possible! In the meantime, take care of your teeth with daily brushing and flossing, eat a dental-healthy diet, and visiting our Kingston, ON office as recommended.

You do your best to keep your teeth intact and in place—but if you lose one through trauma or decay, talk to Dr. Cosman, Dr. McDonough, Dr. Levac and Dr. Korcok about an implant. Because in any stage of life, the most important result is the happy ending a healthy and confident smile brings you!

Dental-Healthy Snacks for Your School-Aged Child

April 1st, 2025

Kids are constantly active and constantly growing. No wonder they’re constantly hungry! When it’s time for a snack, here are some tips to make between meal treats timely, tasty, and tooth-friendly.

Keep snacks to a minimum

Every time we eat, we’re also providing food for the bacteria in our mouths. Bacteria use sugars to produce acids. These acids weaken our enamel and can lead to cavities. Luckily, we have a natural way of protecting our teeth. Saliva washes away food particles and bacteria, and even provides substances that strengthen our teeth in the hours between meals.

When we eat throughout the day, there is no chance for this recovery period to take place. Small children aren’t usually able to get through the day without a few snack periods, which is perfectly normal. Just try to make sure that snacking doesn’t become all-day grazing!

Avoid foods that contain sugar and carbohydrates at snack time

We know that sugar leads to an increased chance of cavities because bacteria convert this sugar into acids that damage our enamel. But carbohydrates should also be in the no-snack zone. Why? Because carbohydrates break down into sugar very quickly. So while you wouldn’t offer your child a daily mid-afternoon snack of sodas and chocolate bars, those muffins, doughnuts, chips, and bagels should be on the “special treat” list as well.

Dental-healthy snacks

Luckily, we are left with many healthy and convenient choices when your child needs a nibble.

  • Crunchy, crisp fresh fruits and vegetables provide vitamins as well as a gentle scrubbing action to help clean teeth. They are also rich in water, which helps us produce the saliva that naturally washes away food particles and bacteria.
  • Low-fat yogurts and cheeses provide essential calcium for strong teeth and the vitamin D that helps us absorb calcium.
  • Whole grain breads, cereals, and crackers are healthier than products made only with white flour because they retain valuable vitamins and minerals that have been removed from refined grains.
  • Lean meats, peas, legumes, and eggs provide protein that helps build connective tissue and maintain tooth structure.
  • Water helps stimulate saliva production and provides cavity-fighting fluoride. Win/win!

You are constantly looking for ways to make your children’s lives better. Mix and match any of these foods for a snack that’s not only good for their teeth, but rich in the proteins, vitamins, and minerals needed to keep them active and growing throughout their school years. If you have questions about your child’s dietary needs, feel free to ask Dr. Cosman, Dr. McDonough, Dr. Levac and Dr. Korcok at our Kingston, ON office.
