Interproximal Cavities: The Inside Story

May 13th, 2026

Time to brush! So, you make sure you gently brush the plaque off the outside surfaces of your teeth. You want to present a gleaming smile to the world, after all. And you make sure to brush the inside surfaces as well, because who wants to feel a fuzzy patch of plaque every time their tongue hits their teeth? And, naturally, you remember to clean the tops of your molars, because those crevices make them more cavity-prone than any other surface.

Done? Not quite!

You might be surprised to learn that no matter how well you’ve brushed all the visible surfaces of your teeth, you’ve left quite a bit of enamel untouched—the adjoining, or touching, surfaces of the teeth which sit next to each other.

You’ve probably noticed that your bristles can’t . . . quite . . . reach all the enamel between your teeth (especially between your molars!) when you’re brushing. This means that food particles and plaque have an easier time sticking around. And when the bacteria in plaque are left undisturbed, especially with a banquet of food particles available, they produce acids which gradually eat away at the enamel covering our teeth, creating a cavity.

Here’s where we work in some specific dental vocabulary. “Interproximal” means between the adjoining, or touching, surfaces of the teeth. And an interproximal cavity is a cavity which develops on one of those side surfaces of your teeth.

  • Discovering Interproximal Cavities

Clearly, a cavity between the teeth won’t be as obvious as other cavities. How will you know if a dental appointment is in order?

There are typical symptoms which can show up when you have a cavity. Chewing might be painful. You might feel pain or sensitivity when you eat or drink something which is hot, or cold, or sweet. But pain and/or sensitivity aren’t always present, especially when a cavity is just beginning to develop.

Regular exams are important so you can catch small cavities before they become more serious. That’s why, at your regular dental exams, Dr. Cosman, Dr. McDonough, Dr. Levac and Dr. Korcok will always check for any signs of decay on every surface of each tooth, including those places which aren’t easily visible. And that’s why X-rays can be an important tool for locating these tricky cavities.

  • Treating Interproximal Cavities

If Dr. Cosman, Dr. McDonough, Dr. Levac and Dr. Korcok and our team finds a cavity between your teeth, there are different treatment options available depending on the size of the cavity:

  • A typical cavity will require a filling. The decay will be removed, and then the area will be cleaned and filled. You’ll probably choose a filling material which can be matched to your enamel color if the restoration will be noticeable.
  • If decay has spread to the pulp chamber inside the tooth, a root canal is often the best treatment option, with a crown applied afterward to protect the tooth.
  • A tooth so decayed or infected that it cannot be saved might require extraction.

Dealing with any weakness in a tooth as quickly as possible is always better than waiting until a more complicated treatment option is needed. Of course, the best treatment is prevention, and, luckily for us, it’s not a complicated process at all.

  • Preventing Interproximal Cavities

In fact, it’s about as basic as it can be—brush and floss effectively. We recommend brushing for two minutes at least twice a day and flossing once each day. While most of us are good about keeping up with brushing, sometimes that daily flossing is more a goal than a reality.

But it’s flossing which really does the trick when it comes to interproximal cleaning. If you floss correctly, food particles and plaque are removed from between the teeth and around the gumline—places where bristles just can’t reach. The next time you get your teeth cleaned at our Kingston, ON office, ask for tips on how to perfect your technique. And, if you have difficulty flossing, ask about alternatives such as water flossers and interproximal brushes.

Preventing cavities on the exterior surfaces of your teeth is probably pretty much automatic by now, but don’t forget the potential for stealth decay! If Dr. Cosman, Dr. McDonough, Dr. Levac and Dr. Korcok and our team find signs of erosion on the sides of your teeth, or if your hygienist lets you know that you’ve got a lot of interproximal plaque buildup, work with us to make sure “interproximal cavity” doesn’t become a working part of your dental vocabulary.

HPV and Oral Cancer

May 13th, 2026

HPV, or human papillomavirus, is the most common sexually transmitted infection in the country. There are over 100 strains of HPV, and, while most of these infections leave our systems on their own with no long-term ill effects, some cancers have been linked to certain “high risk” strains of the virus. One of these strains, HPV16, increases the risk of oral cancer.

HPV-related oral cancer most often appears in the oropharynx. This area of the mouth includes:

  • The base, or back, of the tongue
  • The soft palate
  • The tonsils
  • The back and sides of the throat

While HPV-related oral cancers can appear in other parts of the oral cavity, they most typically occur at the back of the throat and tongue and near the folds of the tonsils. Because of this location, oropharyngeal cancer can be difficult to detect. This is one more important reason to maintain a regular schedule of dental exams. Our examination doesn’t focus only on your teeth and gums. We are trained to look for cancerous and pre-cancerous conditions in the mouth, head, and neck to make sure you have the earliest treatment options should they be needed.

If you discover any potential symptoms of oropharyngeal cancer, call us for a check-up. These symptoms can include:

  • Trouble moving the tongue
  • Trouble swallowing, speaking, or chewing
  • Trouble opening the mouth completely
  • A red or white patch on the tongue or the lining of the mouth
  • A lump in the throat, neck, or tongue
  • A persistent sore throat
  • Ear pain
  • Unexplained weight loss
  • Coughing up blood

Not every symptom is caused by cancer, but it is always best to be proactive. HPV-related oral cancer is rare, but it is on the increase. While HPV-positive oral cancers generally have a better prognosis than HPV-negative oral cancers, early diagnosis and treatment are still essential for the best possible outcome.

Finally, if you are a young adult or have an adolescent child, talk to Dr. Cosman, Dr. McDonough, Dr. Levac and Dr. Korcok and to your doctor about the HPV vaccine, which is effective before exposure to the virus occurs. Most HPV vaccines, while not designed specifically to prevent oral cancer, prevent the HPV16 strain from infecting the body—the very same strain that causes the majority of HPV-related oral cancers.  Although no studies have shown definitive proof yet, there is strong feeling in the scientific community that these immunizations might protect against HPV-positive oral cancer as well as cervical, vaginal, and other cancers. It’s a discussion worth having at your next visit to our Kingston, ON office.

The Connection Between Your Mouth and Your Heart

May 6th, 2026

At Cataraqui Dental Centre, we know your dental health is closely connected to your overall health. We also know that the mouth can oftentimes be the first place to show signs of other bodily health issues.

Studies have shown possible links between periodontal (gum) disease and heart disease, and researchers have found that people with gum disease have an elevated risk of suffering from a stroke or developing coronary artery disease. Believe it or not, an estimated 70 to 80 percent of North American adults currently have some form of gum disease.

Gum disease, which affects the tissues that surround and support the teeth, is an infection caused by a sticky film of bacteria called plaque that forms on the teeth, mainly along the gum line. In its early stages, called gingivitis, gum disease can be treated by Dr. Cosman, Dr. McDonough, Dr. Levac and Dr. Korcok and often reversed.

To help keep your mouth and heart healthy, we’ve provided following tips to help prevent problems before they arise:

  • Brush your teeth with fluoride toothpaste at least twice a day. Make sure you brush gently beneath the gum line around each tooth.
  • Floss at least once a day.
  • Have a dental checkup and cleaning twice a year, or as recommended.
  • Eat a healthy diet. This includes avoiding foods with a high concentration of sugars or starches and consuming more fruits and vegetables.
  • Avoid tobacco and copious levels of alcohol. If you smoke, quit. And remember, heavy drinking dramatically increases the risk of developing mouth and throat cancer.

Don’t put off your next visit to Cataraqui Dental Centre any longer! If it has been a while since your last visit to our Kingston, ON office, please give us a call!

Four Tips for Soothing a Toothache

May 5th, 2026

Whether it’s a dull and throbbing ache or a sharp pain, toothaches can come in many different forms. Chances are you’ve had the discomforting experience once or twice in your life. It’s the type of experience that nobody wants to have, because a toothache can be as annoying as fingernails scratching a chalkboard.

What’s a good way to describe a toothache? Let’s see … your mouth feels as if it’s being besieged by one of those Loony Tunes-style jackhammers. As fate would have it, toothaches always seem to occur over the weekend or after-office hours, leaving you to suffer and forcing you to cancel your reservation at that high-end restaurant you’ve been anticipating all week.

Not so fast!

While you’re probably going to want to skip the rib-eye steak, there are numerous tried-and-true home remedies you can use to ease the pain until you can make an appointment with our office. Here’s a look at four ways to soothe a toothache.

  1. Don’t underestimate the power of salt water. Rinsing your mouth with warm salt water will both soothe your toothache and disinfect your mouth. However, make sure the water is warm; cold water can further exacerbate a sensitive tooth. Follow up the saltwater rinse by swishing your mouth with hydrogen peroxide.
  2. Clove oil, eucalyptus oil, peppermint oil, and vanilla extract are proven to be comforting elixirs. Dip a cotton swab in one of these mixtures and apply it to your tooth and gums. These substances, which you may even have in your kitchen cupboards, are known to have pain-relieving qualities. For the best results, repeat the application throughout the day.
  3. Eating yogurt is good for toothaches and mouth pain. Yogurt is filled with healthy bacteria that combat pain. Afterward, place a cold compress on your jaw.
  4. Try flossing. Your toothache might be throbbing and severe, but there’s always a chance the pain is caused by a piece of food awkwardly lodged in your teeth.

We hope that helps! Give Cataraqui Dental Centre a call to learn more!
