Antibiotic Prophylaxis or Premedication

December 24th, 2025

In years past, it was often recommended that dental patients who had a history of heart problems or other conditions, such as joint implants, be given antibiotics before any dental work. This pre-treatment is called prophylaxis, based on the Greek words for “protecting beforehand.” Why would Dr. Cosman, Dr. McDonough, Dr. Levac and Dr. Korcok suggest this protection? It has to do with possible effects of oral bacteria on the rest of the body.

Our bodies are home to bacteria which are common in our mouths, but which can be dangerous elsewhere. If these oral bacteria get into the bloodstream, they can collect around the heart valve, the heart lining, or blood vessels. A rare, but often extremely serious, infection called infective endocarditis can result.

It is no longer recommended that every patient with a heart condition take antibiotics before dental procedures. Doctors worry about adverse effects from antibiotics or, more generally, that an overuse of antibiotics in the general population will lead to more strains of antibiotic-resistant bacteria.

There are some patients, however, who are at a higher risk of developing infective endocarditis, and who should always use preventative antibiotics. Generally, premedication is advised if you have one of these risk factors:

  • A history of infective endocarditis
  • Certain congenital heart conditions (heart conditions present since birth)
  • An artificial heart valve
  • A heart transplant

Your cardiologist will know if prophylaxis is advisable, and if you are taking any drugs which could interact with antibiotics. Always talk to your doctor about any dental procedures you are planning, particularly if they are invasive procedures such as gum surgery or extractions.

If you believe you would benefit from antibiotics before dental treatment at our Kingston, ON office, the most important first step is to talk with your doctors. We are trained to know which pre-existing health conditions call for prophylaxis, which dental procedures require them, which antibiotics to use, and when to take them. Tell us about any health conditions you have, especially cardiac or vascular issues, and any medication allergies. Working with you and your doctor to protect your health is our first priority, and having a complete picture of your medical health will let us know if antibiotic prophylaxis is right for you.

Top Five Ways to Improve Heart Health

December 23rd, 2025

While there is no definite evidence that if your prevent gum diseases, like periodontitis, that you may be able to prevent a heart condition or heart disease. The only thing experts, like Dr. Cosman, Dr. McDonough, Dr. Levac and Dr. Korcok, know for sure is that if you take care of your gums it can lessen atherosclerosis, (build-up of artery clogging plaque) that may result in a heart attack or stroke.

Could periodontal disease cause heart attacks?

Regardless of your oral health, if you're at a high risk for heart disease, you need to take action.

  • Maintain a healthy weight or lose weight.
  • Consume healthy foods and beverages.
  • Exercise several days the week. Walking is a powerful and lightweight exercise and will clear your head while helping your body get or stay healthy.
  • Control any medical conditions you may have such as high cholesterol, diabetes, or high blood pressure.
  • Reduce your stress. Have lunch with a friend, go for a walk in the park, take a bubble bath, mediate, or do whatever you find relaxing.
  • Get a social life. Laughing reduces stress and “feel good” hormones. Everyone needs to feel like they are a part of something: join a book club or any activity where you can interact with other people at least once or twice a week
  • Be sure to get enough sleep. The recommended amount is eight to nine hours a night. It has been proven that a lack of sleep increases your risk for angina, strokes, and heart attacks.
  • Practice good oral hygiene to keep bacteria in check and your mouth healthy.

Contact our Kingston, ON office if you have questions about your heart and oral health. If you take practice good oral hygiene, both your mouth and your heart will thank you.

Whitening an Artificial Tooth

December 17th, 2025

It’s a bit of a contradiction: you are justifiably proud of your beautiful dental work, but you don’t want it to be obvious when you smile. Dental prosthetics such as veneers and crowns should blend perfectly with your natural teeth. If you have noticed your veneers are a different shade than your other teeth, or have a crown that is visibly darker than the teeth surrounding it, you are probably wondering if there is any way to lighten and whiten an artificial tooth surface. There is no one right answer, but let’s examine a few common scenarios to find the best solution for you.

If You Haven’t Started Your Dental Work and Want a Whiter Smile

If you are planning on getting a veneer or a crown, it’s best to take advantage of teeth whitening before you have the work done. Choosing a shade of bright white for your veneers and then trying to whiten your natural teeth to match it afterward is almost impossible. It’s a good idea to talk to us about whitening beforehand, and, if this is the best way to achieve the look you want, Dr. Cosman, Dr. McDonough, Dr. Levac and Dr. Korcok can match the color of your new prosthetic to your newly whitened smile. The goal is to make your new veneer or crown a perfect match to your natural teeth.

If You Have Existing Veneers, Crowns, or Other Artificial Surfaces

Porcelain veneers cannot be whitened, but the good news here is that they don’t stain the way natural teeth do. Unlike our teeth, porcelain is non-porous, so it is very difficult for typical culprits such as coffee, tea, or red wine to have as much effect. Any surface stains that appear can usually be gently removed with a professional cleaning and polishing, where we will take care not to scratch the delicate surface of the veneer. Porcelain crowns and implants, like veneers, can be brightened with a professional surface cleaning, but their original color cannot be changed.

Composite veneers and composites used in dental bonding are more porous and therefore more likely to stain. They are also immune to whitening, but might respond somewhat to a careful professional polishing at our Kingston, ON office.

Finally, if the color of your existing dental prosthetics is a concern, replacement is an option we can consider together.

Whether you have existing veneers and crowns or are planning future dental work, please talk with us about achieving a seamless blend of old and new for a beautiful, natural smile. It’s a bit of a contradiction: the best work is the work no one notices!

When to Begin Dental Care for Your Baby

December 16th, 2025

Children’s oral health differs from the needs of adults in many ways. It’s vital for you to understand what your child needs to keep his or her teeth healthy. Dr. Cosman, Dr. McDonough, Dr. Levac and Dr. Korcok and our team are here to answer your questions to set you and your little one up for success.

In-home dental care should start as soon as your baby show signs of developing that first tooth. At around age one or two, bring your son or daughter to our Kingston, ON office. Dr. Cosman, Dr. McDonough, Dr. Levac and Dr. Korcok will examine your child’s tooth development and gum health.

The initial appointment will focus on getting your youngster familiar with our office and comfortable with our staff. We will go over several general matters during that first visit:

  • Inspect for signs of decay or other tooth or gum problems
  • Check for gum disease or cavities
  • Examine your child’s bite and possible misalignment
  • Clean the teeth, and apply fluoride if your child is old enough
  • Talk with parents about proper oral health
  • Give you tips for brushing and flossing your little one’s teeth
  • Answer any questions you may have about caring for your son or daughter’s teeth

Once your child is old enough for the first dental visit, you should schedule regular cleanings every six months. Call our Kingston, ON location if you have any conflicts or questions.
