Dangers of Alcohol and Oral Health

August 5th, 2025

We often have patients who ask, “Can drinking alcohol affect my oral health?” There are, in fact, a few reasons why that martini may not be good for your pearly whites.

In addition to creating an overly acidic environment in your mouth, alcohol severely dehydrates oral tissues because of its desiccant and diuretic properties. Because alcohol saps oral tissues of their moisture so readily, saliva glands can't keep enough saliva in the mouth to prevent dry mouth. In addition, saliva contains antibacterial properties that inhibits growth of anaerobic bacteria, a destructive type of oral bacterial responsible for tooth decay, gingivitis, chronic bad breath, and periodontitis.

What are anaerobic bacteria?

When there is a lack of saliva flow in the mouth and the mouth cannot naturally cleanse itself of oral debris (food particles, dead skin cell, mucous), conditions develop that promote activity of anaerobic bacteria, or bacteria that thrive in dry, airless places. These anaerobes also flourish when an unending supply of proteins (food debris) are available to consume, creating rapidly multiplying layers of plaque that stick to teeth and demineralizes tooth enamel unless removed by brushing and professional dental cleanings.

Oral Cancer and Alcohol

Acetaldehyde is a chemical compound leftover after the liver has metabolized alcohol. Capable of causing genetic mutations, acetaldehyde is also a known carcinogen that contributes to the ill feelings of hangovers. Although most metabolism of alcohol is done in the liver, evidence shows that metabolism also occurs outside the liver and that enzymes in the mouth could encourage accumulation of acetaldehyde in oral tissues.

When combined with poor oral health, smoking, and other detrimental lifestyle factors, alcohol may be considered a primary contributory factor in the development of oral cancer.

Even if you don't drink or drink only occasionally, remaining aware of symptoms that may indicate oral cancer will improve your chances of recovering successfully when you start treatment in the early stages of oral cancer. Signs include red or while speckled patches in the mouth, unexplained bleeding, lumps/swellings, chronic ear or throat pain, and areas of numbness in the mouth or on the face.

If you have any questions about alcohol and its connection to oral health, don’t hesitate to ask Dr. Cosman, Dr. McDonough, Dr. Levac and Dr. Korcok at your next visit to our Kingston, ON office.

A Prescription for Oral Health

July 30th, 2025

You and your dentist are essential partners in making sure you have the best dental care. You do your part by eating a tooth-healthy diet, brushing and flossing as recommended, and seeing Dr. Cosman, Dr. McDonough, Dr. Levac and Dr. Korcok regularly for checkups and cleanings.

And one more essential step you can take for your dental health? Let Dr. Cosman, Dr. McDonough, Dr. Levac and Dr. Korcok know which prescriptions and over the counter medications you’re taking.

Medications Have Oral/Dental Side Effects

We’ve all grown used to hearing “Possible side effects include . . .” at the end of every pharmaceutical commercial. That’s because those unintended side effects can affect our health in any number of unexpected ways—and this includes oral health.

For example, a common side effect of many medications is xerostomia, or “dry mouth.” Because saliva helps keep our teeth and gums healthy by washing away food particles and oral bacteria and by reducing acidity in the mouth, a reduction in saliva production means a greater risk of cavities, gum disease, oral infections, denture discomfort, and bad breath.

Knowing a patient is taking one of the hundreds of medications which cause xerostomia allows Dr. Cosman, Dr. McDonough, Dr. Levac and Dr. Korcok to both monitor the condition and suggest the most effective treatment options to control unpleasant symptoms.

Medications can cause not only dry mouth, but excessive gum tissue growth, oral sores, tooth discoloration, and changes in taste, among other side effects, so knowing which medications you’re taking can provide essential information for the diagnosis and treatment of these conditions.

Medications Interact

Medication might be needed for your dental treatment. Because certain drugs, supplements, and even some vitamins and foods can affect the way our bodies metabolize, absorb, and respond to other medications, we need to know which medicines you’re taking to arrive at your best treatment options.

  • There are different classes of antibiotics used to treat oral infections. Knowing your medical history enables Dr. Cosman, Dr. McDonough, Dr. Levac and Dr. Korcok to choose an antibiotic option which won’t interact with your other medications.
  • Local anesthetics such as lidocaine, which numb the area to be treated, can also interact with certain medications. Dr. Cosman, Dr. McDonough, Dr. Levac and Dr. Korcok can prescribe an alternative local anesthetic or adjust the dosage as needed.
  • If you will be using sedation during your procedure, you have several options, including nitrous oxide gas, oral sedation, or IV sedation. Be sure we know about all of your medications beforehand because of possible interactions. Changes can be made to the type of sedation and/or the dosage as needed.

Medications Impact Treatment

It’s important for Dr. Cosman, Dr. McDonough, Dr. Levac and Dr. Korcok to know if any of your medications will affect standard treatments.

Anticoagulants, for example, are a necessary medication for preventing blood clots from forming, and are often prescribed for certain heart conditions, after joint replacement surgery, or for anyone at risk for developing blood clots. Because these medications prevent the blood from clotting, it’s important to let us know if you are taking such drugs before any kind of oral surgery.

If needed, Dr. Cosman, Dr. McDonough, Dr. Levac and Dr. Korcok can work with you and your doctor to create a treatment plan which will be safe, effective, and designed to work with any of your medications. You should never discontinue taking your prescribed medications before dental work without medical approval, as this can be dangerous.

We need the most up to date information about your health to provide you with the best care possible. Knowing which medications you take and why you take them can help us:

  • Diagnose and treat any side effects from non-dental medications which have affected your oral health,
  • Prevent drug interactions from occurring, and
  • Tailor your treatment to your specific medical needs.

Your prescriptions, over the counter medications, and even herbal supplements and vitamins are essential information. It’s a good idea to make a list before your next appointment at our Kingston, ON office so you have specific medications and their dosages at hand. It’s one small—but vital—step you can take to work with Dr. Cosman, Dr. McDonough, Dr. Levac and Dr. Korcok for your best dental health!

Post Oral Surgery: Signs of Infection

July 29th, 2025

Oral surgery can be intimidating, especially if you show any signs of an infection afterwards. Dr. Cosman, Dr. McDonough, Dr. Levac and Dr. Korcok and our team want you to be informed about what to watch for after you’ve undergone surgery.

Oral surgery procedures are intended to reduce pain and prevent infection. Sometimes complications occur after your surgery, and if infection ensues, it will require swift medical attention.

People undergo oral surgery for many reasons, such as:

  • Impacted or infected teeth
  • Tooth loss, jaw problems
  • Facial injuries or infections
  • Birth defects
  • Sleep apnea

Symptoms of Infection

  • Pain that won’t go away with medication
  • Steadily swelling of gums, jaw, or face
  • Redness or oozing of pus from the area
  • Fever that doesn't subside
  • Difficulty opening the mouth or jaw
  • Excessive bleeding for 24 hours
  • Difficulty breathing or swallowing (emergency situation)

After the initial surgery, don’t become worried right away if you notice any of these symptoms. It’s normal to show some blood and swelling after surgery, but that should stop fairly soon with the help of gauze and medication.

You will most likely be numb from the procedure and we will advise you to avoid hard foods for the first day. Pain medication will be administered, and you should take it before you begin to notice pain. A cold compress can also help with swelling and initial pain.

You will be advised not to brush your teeth in the region where the surgery occurred. You may use a prescription mouth rinse, or you can gargle with warm salt water to reduce the swelling. If you follow these directions, you can speed the healing process for a quick recovery.

Don’t fret: a post-surgery infection is not a common development. It happens most often to people who have a compromised immune system or diabetes. Let Dr. Cosman, Dr. McDonough, Dr. Levac and Dr. Korcok know beforehand if you have either of these and we may prescribe an antibiotic to help prevent the spread of infection in the areas of your mouth that get worked on.

If you think you may be experiencing complications after a surgery, please don’t hesitate to reach out to our Kingston, ON office for advice.  

How do I know if I need a root canal?

July 23rd, 2025

Tooth decay affects everyone, with studies reporting that 92% of adults have had a cavity at one point in their lifetime. In more serious instances of tooth decay, however, the nerve of the tooth may become infected. This type of infection requires a root canal, in which the affected nerve is removed, and the interior of the tooth is cleaned and filled.

Tooth Anatomy

Although each tooth is covered by a hard outer shell, the interior of a tooth consists of dental pulp. This pulp is soft, containing blood vessels that bring nutrients to the tooth. Each tooth also has an associated nerve, which resides within a root canal passing from the tooth’s root into the dental pulp. This nerve provides information about temperature, allowing teeth to sense heat or cold.

Symptoms of Nerve Infection

Damage to the dental pulp or nerve tissue leads to a rapid multiplication of bacteria within the interior of the tooth. The result may be an abscess, a small pocket near the root of the tooth that becomes full of pus. This infected area commonly causes the following symptoms:

  • Intense pain or sensitivity when pressure is applied to the tooth
  • Sensitivity to hot or cold temperatures, even after the heat or cold has been removed
  • Darkening or discoloration of the affected tooth
  • A small, persistent pimple that forms on the gums
  • Swollen or tender gums
  • Swelling in other areas of the face, neck, or head

Nerve infection may occur due to deep decay, although repeated dental procedures, facial trauma, chipping or cracking of a tooth, or large fillings may also contribute to an abscessed tooth.

What to Do if You Think You Need a Root Canal

Only a visit to Dr. Cosman, Dr. McDonough, Dr. Levac and Dr. Korcok can confirm whether a tooth’s nerve has become infected. We will perform an oral examination and X-rays to confirm whether the tooth is abscessed. If a root canal procedure is needed, a small hole will be placed in the tooth. The pulp and nerve tissue are removed from the tooth, which is thoroughly cleaned and filled. Then, the hole is sealed with a special compound to prevent bacteria from entering the tooth’s interior. The entire procedure is performed under local anesthesia to numb pain.

If you think you may have tooth or nerve decay, call our Kingston, ON office today to schedule a diagnostic appointment.
