You never know when a dental problem may arise. Unfortunately, they don’t necessarily occur during office hours. Dr. Cosman, Dr. McDonough, Dr. Levac and Dr. Korcok can provide you with the proper information and treatment options to prevent the problem from becoming worse.
Abscess
An abscess is a bacterial infection, and will normally cause pain and swelling around the affected tooth and gum area. Though antibiotics are not always necessary, you should be seen by Dr. Cosman, Dr. McDonough, Dr. Levac and Dr. Korcok as soon as possible. If left untreated, the infection may grow and cause more serious issues.
Toothache
Toothaches can have many causes. Sometimes it’s as simple as food lodged between your tooth and gums. Rinse your mouth with warm water and try flossing the area to dislodge the particle. If your gums begin to bleed, stop flossing.
Fractures or cavities can also cause toothaches as well as sensitivity to heat or cold. Please schedule an appointment to ensure a minor problem doesn’t develop into a serious one. You may require acetaminophen or another pain reliever before your visit.
If you can’t be treated right away, keep these tips in mind:
- If you have fractured a tooth, rinse the area with warm water to keep the surfaces clean. Apply a cold compress to the outside of your facial area to reduce swelling.
- A tooth that has been knocked out should be kept moist, in a clean container, until you can receive treatment.
- Do not apply aspirin directly to a damaged tooth or gum area, because this can cause tissue irritation.
- If you suspect your jaw has been broken, go to an emergency room immediately.
- If you have bitten or damaged your lips or tongue, rinse your mouth well with warm water. If bleeding continues, seek other medical attention right away.
If you experience an emergency, please contact our Kingston, ON office and provide us with as much information as possible. This way, we can offer recommendations that will assist you until you’re able to arrive for an appointment.
Remember: procrastinating about getting treatment can turn a minor problem into a major one!

Sealants offer many benefits, but the best is their ability to protect your molars. Molars are full of small caverns that can be the perfect breeding ground for tooth decay and plaque buildup.
Use of protective sealants prevents this buildup from happening. Although children often receive sealants for routine preventive care, they aren’t the only ones who can benefit from this treatment. Sealants can also help adults who have deep canyons or grooves in their teeth.
They are commonly placed on the rear molars that tend to suffer the most decay. Because your molars are used substantially as grinding surfaces, food is more likely to be trapped among them.
Sealant solution consists a composite material that contains bonding agents that seal the top of your teeth. The process is quick and painless, which makes it a great solution for both children and adults who have had trouble with cavities and tooth decay. Sealants also last for several years, and repair is a simple process that can be completed by Dr. Cosman, Dr. McDonough, Dr. Levac and Dr. Korcok.
The process of putting sealants on teeth starts with the tooth getting cleaned. We clean it with a type of baking soda spray called sodium bicarbonate. Then acid is etched onto the teeth to rough up the surface.
We apply an alcohol-based liquid to dry the area where the sealant is supposed to go. After it completely covers the surface of the treated teeth, the sealant is cured with a light that makes it hard and long-lasting.
Getting sealants can prevent the possible restorative costs that come from cavities. Sealants help to protect your tooth’s enamel from harmful acids and prevent decay, which can be an investment in itself. The whole process is quick, so it should be easy to schedule an appointment at Cataraqui Dental Centre.
Feel free to call our Kingston, ON location and we can answer any questions you have about this service.

Temporomandibular joint disorders (TMD) describe a set of conditions that involve trouble with your jaw and face muscles. They result from a problem in the temporomandibular joint (TMJ), which is a hinge that connects the temporal bones, in your skull in front of each ear, to your jaw. The joint enables you to talk, yawn, and chew by letting your mouth move.
TMD can be very painful and interfere with functions such as eating and speaking. This what to watch for and how to try to prevent TMD.
Risk Factors for TMD
You are at higher risk for TMD if you are a women than if you are male. The disorder is most common among adults between the ages of 20 and 40 years. Other risk factors for TMJ disorders include the following.
- Arthritis in the area, making movement more difficult
- Excessive tooth grinding, because it increases stress on the joint
- General stress, which can lead you to clench your teeth and strain facial muscles
Symptoms of TMD
Symptoms of TMD can last for just a short while, or for several years. Seeing Dr. Cosman, Dr. McDonough, Dr. Levac and Dr. Korcok is important if your symptoms make it impossible for you to eat regularly or if you have unbearable pain or discomfort. The following symptoms can occur on both or one side of your face.
- Aching or very tired facial muscles
- Jaws that are fixed open or shut without you being able to unlock them
- Grating or popping sounds when you chew or close or open your mouth
- Pain in the entire area, including the mouth, jaw, neck, or shoulders, that comes on when you chew or yawn
Preventing TMD
You can try to prevent TMD by focusing on reducing risk factors. If you grind your teeth at night, ask Dr. Cosman, Dr. McDonough, Dr. Levac and Dr. Korcok about wearing a mouthguard. If you are overly stressed, look into ways to better manage your stress and relax your muscles. Another strategy for trying to prevent the development of TMD is to avoid chewing gum, since that puts stress on your jaw.
If you have questions about TMD, don’t hesitate to contact our Kingston, ON office.

Why does gum disease develop? Our mouths are home to bacteria, which form a film called plaque. Plaque sticks to the surfaces of our teeth, at the gumline, and can even grow below the gumline. And this bacterial growth leads to inflammation and gum disease.
When the disease progresses, the gums gradually pull away from the teeth leaving pockets which can be home to infection. Toxins can attack the bone structures and connective tissue, which support our teeth. Left untreated, periodontal disease can lead to serious infection and even tooth loss.
Because we are dealing with bacteria, it makes sense that antibiotics are one way to combat gum disease. Depending on the condition of your gums, we might suggest one of the following treatments:
- Mouthwashes—there are mouthwashes available with a prescription that are stronger than over-the-counter antibiotic formulas, and can be used after brushing and flossing.
- Topical Ointments—These ointments or gels are applied directly to the gums, most often used for mild forms of the disease.
- Time-release Treatments—If there is severe inflammation in a pocket, we might place a biodegradable powder, chip, or gel containing antibiotics directly in the affected area. These minute methods release antibiotics over a period of time as they dissolve.
- Pills and Capsules—For more serious periodontal disease, you could be prescribed an oral antibiotic. Take in pill or capsule form as recommended, and always finish the entire prescription.
Talk to Dr. Cosman, Dr. McDonough, Dr. Levac and Dr. Korcok at our Kingston, ON office before beginning a course of antibiotics. It’s important to know if you have any allergies to medications, what to look for if you might have an allergy you didn’t know about, if you are pregnant or breast-feeding, or if you have any health concerns that would prohibit antibiotic use. Talk to us about possible side effects and how to use the medication most successfully. With proper treatment, we can treat gum disease as quickly and effectively as possible, and provide advice on maintaining a periodontal routine that will keep your gums and teeth healthy for years to come.
