What to Do If You Lose a Filling

February 25th, 2026

It really doesn’t happen very often. But sometimes you bite into something that is much harder than you anticipated. Sometimes you grind your teeth without realizing the pressure you’re putting on them. Sometimes you have a cavity that has stealthily developed beneath an earlier filling. And the result is—sometimes you lose a filling.

What to do when this happens? If you’re at a loss for ideas, we have some suggestions.

  • Don’t panic

Usually, a cracked, broken, or lost filling is not an emergency situation. That being said, it’s still important to . . .

  • Call us immediately

Dr. Cosman, Dr. McDonough, Dr. Levac and Dr. Korcok will be able to give you the best advice as to how to take care of your tooth until you can make an appointment. And if your dental problem might be a dental emergency, we can make sure you are seen as soon as possible.

  • Take care of your tooth

Keep your tooth and the area around it clean. Brush gently to keep food particles away from the newly exposed tooth surface. You can (carefully) rinse around the area with a bit of water or salt water as recommended.

Your lost filling might not inconvenience you at all. But if you feel sensitivity when the tooth is exposed to air, or when you eat hot or cold foods, or if you feel pain when you bite down, let us know. We can recommend some over the counter medications and pain relievers that can help.

If you’re experiencing severe pain, call us at once.

  • Diet

This might not be the time for sticky caramels, frozen treats, or extra-hot beverages. Make yourself comfortable by avoiding chewing with your compromised tooth, and postponing foods that could trigger sensitivity.

  • Make a dental appointment as soon as you can

Don’t put off treatment, even if the filling was a small one, and even if the tooth is causing you no discomfort.

There might be further damage or decay that should be treated. A tooth that required a large filling is often more fragile than an intact tooth, and might need to be fitted with a crown in order to protect it. A missing filling might reveal deep decay which has exposed the pulp of the tooth to infection or damage, and a root canal might be necessary. A seriously damaged tooth might require extraction. Delaying treatment could result in a more complex restoration.

See us as soon as you discover a problem with your filling, and we will make sure not only that your tooth is treated appropriately, but that the reason for the lost filling is discovered. While no filling lasts forever, if the cause of your lost filling is tooth grinding or decay, it’s important to be proactive to prevent further problems.

Losing a filling? It really doesn’t happen very often. But that’s not a lot of comfort if you do happen to lose or break a filling. If you’re at a loss for what to do next, contact our Kingston, ON office. You’ll find yourself smiling again in no time!

Healthy Gum, Healthy Mouth

February 24th, 2026

“Shouldn’t that be healthy gums,” you’re thinking? And, of course, you’re correct. Healthy gums are extremely important not only for our dental well-being, but for our overall physical health.

But that’s a subject for another blog! Today, we’re talking about healthy gum—chewing gum, that is. Because choosing the right chewing gum can actually improve your dental health.

Oral bacteria use the foods we eat, especially sugars and simple carbs, as fuel to produce acid. These acids attack our tooth enamel, gradually weakening the minerals in the tooth surface and allowing cavities to develop. Clearly, we want to reduce these acids to help prevent decay. Luckily, our bodies have a natural defense against acid attacks—saliva.

Saliva works to protect our enamel in three ways:

  • It helps neutralize and wash away acids in the mouth.
  • It rinses away the food particles which bacteria feed on.
  • It strengthens teeth by providing the necessary minerals our enamel needs to “remineralize” after acids have weakened the tooth surface.

Studies have concluded that chewing sugarless gum for 20 minute after a meal can help prevent cavities. Why? Because chewing gum increases saliva production. You are actually reducing the effects of harmful acids, washing food particles away from your teeth, and strengthening weakened enamel with every stick! Some artificial sweeteners are even thought to inhibit the growth of the bacteria that lead to decay.

With all that in mind, it’s also healthy to know when you shouldn’t chew gum:

  • When the gum contains sugar. Even with an increase in saliva production, bathing your teeth in sugar as you chew does your enamel no favors!
  • When you wear braces. Gum can stick to your brackets and between your brackets and your wires. And while trying to clean gum from your appliance is no one’s idea of fun, an even more unpleasant possibility is the chance that gum might bend your wires out of shape. Sugarless gum is not quite as sticky as regular gum, but before you open that first pack, check with your orthodontist to see if you might be putting your orthodontic work at risk.
  • When you have jaw problems such as TMD, TMJ or other temporomandibular concerns, or if you develop jaw pain while chewing gum.
  • You should never give gum to a child too young to understand that it should not be swallowed. Beyond acting as a choking hazard, continual gum swallowing can lead to diarrhea, blockages, abdominal pain and other serious problems. Talk to your Dr. Cosman, Dr. McDonough, Dr. Levac and Dr. Korcok about the right age for chewing gum.

While chewing sugarless gum has the potential to improve dental health, remember it should never take the place of regular brushing and flossing—still the best way to prevent cavities at home. Talk to Dr. Cosman, Dr. McDonough, Dr. Levac and Dr. Korcok about the possible benefits of sugarless gum at your next visit to our Kingston, ON office, and we can make recommendations based on your individual dental history. Because whether it’s healthy gums or healthy gum, we’re here to help.

The Evolution of the Toothbrush

February 18th, 2026

Oral hygiene has always been an important part of maintaining overall health. For thousands of years, humans have found ways to keep their teeth and mouths clean. According to the Canadian Dental Association, “early forms of the toothbrush have existed for nearly 5,000 years.” But what exactly did the first toothbrush look like?

Toothbrush Timeline

With a little help from the internet, Dr. Cosman, Dr. McDonough, Dr. Levac and Dr. Korcok and our team have compiled a timeline with some interesting details about the evolution of the toothbrush:

  • 3000 BC – Perhaps the earliest form of the toothbrush, the “chew stick” was used by Ancient civilizations. People would rub this thin twig with a frayed end against their teeth to remove food and plaque.
  • 1498 – The bristle toothbrush was invented in China and had many similarities to the toothbrushes used today. These devices were made by attaching the stiff, coarse hairs from the back of a hog’s neck to handles that were typically made from bone or bamboo.
  • 1938 – Signaling the end of the boar bristle, Dupont de Nemours introduced nylon bristles, and Americans welcomed Doctor West’s Miracle Toothbrush, the first nylon toothbrush.
  • 1960 – The Squibb Company introduced Broxodent, one of the first electric toothbrushes, to the American market.

Toothbrushes Today

Today, there are many brands of toothbrushes that often advertise different benefits. The variety of options may seem overwhelming, but the most important thing is for you to find a toothbrush that you like and find easy to use.

The CDA recommends that you choose a toothbrush that fits comfortably and allows you to effectively reach all areas of your mouth. Whether you decide to use a manual or a powered toothbrush, make sure that you thoroughly clean all surfaces of your teeth twice a day.

Society has come a long way since the days of the chew stick, but one thing that remains the same is the importance of consistent and effective personal oral hygiene.

Dentistry around the World

February 17th, 2026

From the clinical perspective, dentistry is similar around the world. Dentists, like Dr. Cosman, Dr. McDonough, Dr. Levac and Dr. Korcok, go to school, obtain a license, and work hard to prevent and treat tooth decay, gum disease, oral infections, throat or oral cancer, tooth loss, and other conditions that might limit a person’s ability to smile, bite, chew, or speak. The quality of dental care, however, and the payment method for dental services varies between nations.

Dentistry throughout the World

Developed countries have more dentists per capita than do developing nations, according to the World Health Organization. There is one dentist for every 150,000 people in Africa, for example, as compared to about one dentist for every 2,000 citizens of an industrialized nation. The lack of dentists in developing nations means that dental care is restricted to pain management and emergency care.

Dentistry often reflects the cultural views of a nation. Some cultures acknowledge only the functional aspect of teeth, so dentists focus on preventing tooth decay, gum disease, and tooth loss. Other cultures emphasize aesthetic appearances, so dentists there provide cosmetic procedures in addition to essential oral care.

Each nation imposes its own education and licensure requirements for dentists but most require some college before four years of dental school. The graduate must then pass local or national exams to practice in that region. European schools and standards are similar to the United States.

From the business perspective, dentistry varies between nations. In the United States, a dentist presents to the patient one bill that includes all of the treatment costs, such as the dentist, his assistant, tools, and labs. This allows the dentist to charge a single, easy-to-pay fee for individual procedures, and gives him an opportunity to mark up items and make a profit.

Across much of Europe, a dentist presents two bills to her patient – one for the dentist and another for the lab. This approach may stem from a cultural belief that profiting from healthcare is unethical and that healthcare should be available to consumers at actual cost; public dental clinics and subsidies ensures all citizens have access to dental care, regardless of ability to pay. In most cases, the government is both overseer and provider of dental care.

While the role of the dentist is nearly the same in every country – to ensure the oral health of the citizens – dental care is different in each nation. Regardless, you can rest assured that the care you receive at our Kingston, ON office is held to the highest standard.
