Satisfying a Sweet Tooth

March 17th, 2026

Time for some sweet talk! Many studies have been done to figure out why we enjoy sugar so much. Is it brain chemistry? Is it blood sugar getting a bit low? Is it our bodies craving a quick burst of energy?

It’s probably all of the above and more besides. After all, our biochemistry makes use of sugars on a cellular level. The carbohydrates in our diet break down into sugars, and these sugars are the body’s preferred source of energy.

Problems arise when we get too much of a good thing. There’s a difference between the carbs we need to fuel our bodies and the sugars we add to foods for flavor. Too many added sugars in the diet are linked to a number of medical conditions, including obesity, diabetes, heart disease, even prematurely aging skin.

And, of course, a sugar-heavy diet has a direct effect on your oral health.

There’s no way to sugar coat it. Plaque is mainly composed of bacteria, which feed on sugars. As they digest sugar, they produce acids. These acids attack our enamel, dissolving the calcium and phosphorus minerals which keep it strong. Weakened enamel leaves teeth vulnerable to decay, and decay creates cavities.

It’s natural to want a sweet treat every now and then, but without some attention, it’s easy to go overboard with added sugars and empty calories. If you’re searching for a middle way, balancing your love for sweet things with your love for cavity-free checkups, read on!

Be Choosy

  • Check and compare labels for added sugars. You’ll be surprised how many foods have a high sugar content, even such health-oriented foods as flavored yogurts, sports drinks, fruit drinks, and protein bars.
  • Consider the (sugar) source. White and brown table sugars and syrups break down easily as we’re eating them, adding empty calories which provide little nutrition, and increasing acidic conditions in the mouth.

Fruits, on the other hand, provide vitamins, minerals, antioxidants, and fiber along with their natural sugars. Switch out cookies, cakes, and pastries and their processed sugars for fruit when you crave something sweet.

  • Chocolate lovers, don’t despair! It’s true, unless you’re eating 100% cocoa, you are probably getting added sugar in your candy bar. But dark chocolate is rich in antioxidants, iron, zinc, magnesium, and other essential minerals, too. When you indulge in chocolate, give dark chocolate a try.
  • Not all candies are created equal! Soft candy bars and candies are healthier for your teeth than sticky or chewy confections, which tend to remain on your enamel for quite some time. Choose a treat that won’t stick with you.

Watch Your Timing

  • If you must snack during the day, it’s better to choose foods without a high sugar content. Bacteria use sugars to produce acids right away. Saliva can neutralize acids in the mouth, but it takes at least 20 minutes for the process to start.

More meals mean more sugar, more acid production, and more time for these acids to cause their damage. That’s why we also suggest you . . .

  • Eat your favorite dessert with a meal instead of waiting until later. You’ll be able to enjoy it even more knowing you’re limiting your exposure to harmful acids.
  • Taking your time is not a good idea when it comes to sweets. We don’t mean you should gobble your food. We do mean that taking sips of sugary beverages throughout the day, or sucking on slowly dissolving candies, gives you a lot more exposure to sugar over a longer period of time.

Small Changes Can Make a Big Difference

  • Drink water after enjoying something sweet to help wash away and dilute sugar.
  • Straws protect your teeth from a sugar-bath if you are drinking sodas, sweetened energy drinks, or other sugary beverages.
  • Sugar-free gum provides a burst of sweet flavor without added sugar. And even better? Chewing gum increases saliva, washing away food particles and acids and bathing teeth in enamel-strengthening minerals.

It’s natural to appreciate a sweet treat every now and then. If you’re not ready for a completely treat-free life, talk to Dr. Cosman, Dr. McDonough, Dr. Levac and Dr. Korcok at our Kingston, ON office about the best ways to have your cake and eat it—or even better, to recommend healthy substitutes to satisfy your sweet tooth.

Women’s Medications and Dry Mouth

March 11th, 2026

Women using medication to treat a variety of medical conditions are often unaware of the potential side effects. One common side effect of medications such as blood pressure medication, birth control pills, antidepressants, and cancer treatments is dry mouth. The technical term for dry mouth is xerostomia.

Xerostomia can lead to undesirable effects in the oral cavity including periodontal disease and a high rate of decay. Many women who have not had a cavity in years will return for their routine exam and suddenly be plagued with a multitude of cavities around crowns and at the gum line, or have active periodontal disease. The only thing that the patient may have changed in the past six months is starting a new medication.

Saliva washes away bacteria and cleans the oral cavity, and when saliva flow is diminished harmful bacteria can flourish in the mouth leading to decay and gum disease. Many medications can reduce the flow of saliva without the patient realizing the side effect. Birth control pills can also lead to a higher risk of inflammation and bleeding gums. Patients undergoing cancer treatments, especially radiation to the head and neck region, are at a greatly heightened risk of oral complications due to the possibility of damage to the saliva glands.

There are many over the counter saliva substitutes and products to temporarily increase saliva production and help manage xerostomia. One great option for a woman with severe dry mouth or high decay rate is home fluoride treatments. These work in a number of ways, including custom fluoride trays that are worn for a short period of time daily at home, a prescription strength fluoride toothpaste, or an over the counter fluoride rinse. If you have more questions on fluoride treatments, make sure to ask Dr. Cosman, Dr. McDonough, Dr. Levac and Dr. Korcok at your next visit to our office.

The benefits of many of the medications on the market outweigh the risks associated with xerostomia, however, with regular exams you can manage the risk and prevent many oral consequences of medications.

Losing a Baby Tooth

March 10th, 2026

It seems like yesterday. There you were, comforting your baby through sleepless nights, soothing her with a dentist-approved teether, celebrating as that first tiny tooth poked through her gums. And now here she is running to show you that same tooth, wiggly, loose, and almost ready for the Tooth Fairy. Now what?

Be Prepared

Children normally lose that first tooth somewhere around the age of six, but a year or two earlier or later is not uncommon. If you ever took a business class, you might have heard of the inventory method called “First In, First Out.” Baby teeth operate much the same way! The two bottom front teeth, followed by the two upper front teeth, will probably be the first teeth your child loses. Once you notice some wiggling, let your child know what is going on and reassure her that it is a normal part of growing up.

What to Expect with that First Loose Tooth

Normally, baby teeth become loose when the pressure from the permanent tooth below gradually breaks down the roots of the primary tooth. If your child has a loose tooth, encourage him to wiggle, not pull. Typically, gentle wiggling is all that is needed to free a tooth that has lost most of its root and is ready to be replaced. Avoid pulling or forcing the tooth, because that can cause injury to the root area if the baby tooth isn’t ready to come out. Call our Kingston, ON office if you have any questions about loose teeth. Dr. Cosman, Dr. McDonough, Dr. Levac and Dr. Korcok and our team also have suggestions if the baby teeth don’t become loose on schedule, or if they stubbornly remain in place even after the adult teeth have started to show up. One important note—if your child ever loses a tooth through accident or injury, call us at once. We might need to provide a spacer to give your child’s permanent teeth the proper time and space to come in.

Celebrate this Milestone with Your Child

The arrival of the Tooth Fairy is a familiar way to mark the occasion, and she can leave your child a note, a small gift, even a brand new toothbrush. Or explore other options!

If your child is fascinated by stories and traditions, learn about El Ratón Pérez (Perez the Mouse), a familiar tooth-collector in many Spanish speaking countries, or his French cousin, La Petite Souris (the Little Mouse). In other parts of Europe, Asia and Africa, children throw teeth on the roof, drop them in a glass of water, or hide them in a slipper. This is a great opportunity for you and your child to explore the world!

If your child likes science, look into books that explain the biology of baby and adult teeth in an age-appropriate way. You could print a chart of the primary teeth and take notes on each lost tooth as it makes way for the permanent tooth below. Or track her progress with photos showing the baby tooth, the gap left by the tooth, and the adult tooth as it comes in.

Losing that first tooth is an important moment for your child—and for you. Be prepared to celebrate another milestone together, and always feel free to talk to Dr. Cosman, Dr. McDonough, Dr. Levac and Dr. Korcok if you have any questions about this new stage in your child’s life.

Balancing Act

March 4th, 2026

We’re all trying to find a healthy balance in our lives. Balancing work and home life. Eating a well-balanced diet. Balancing our budgets. Maintaining the right pH balance in our mouths for better dental health. Wait, what was that last one?

You probably don’t spend a lot of time thinking about your pH levels, but if your oral pH is out of balance it can affect the health of your teeth.

What do we mean by pH levels? In biology and chemistry, the pH scale is a tool used to measure the concentration of hydrogen (H⁺) ions and hydroxide (OH⁻) ions in a solution.  

The higher the concentration of hydrogen atoms, the more acidic a solution. The higher the concentration of hydroxide ions, the more alkaline. The pH scale goes from 0 to 14, with the most acidic reading possible rating a 0, and the most alkaline, a 14.

You don’t have to be a biochemist to use the information provided by pH samples. We use pH readings to discover the ideal acid/alkaline conditions in many everyday applications. Azaleas grow best in very acidic soil. Swimming pools should be just a bit alkaline. Brewers test pH throughout the beer-making process for optimal fermentation—and taste.

When it comes to saliva, a neutral pH range of around 6.2 to 7.6 is generally considered normal. High alkalinity in saliva is rare. High acidity levels? Unfortunately, much more common. And an acidic environment has real-world consequences for teeth.

Plaque contains bacteria, which produce acids. Calcium and phosphate, the minerals that help make enamel the strongest substance in the body, are leached out by these acids. The weak spots left behind make enamel vulnerable to further erosion and, eventually, decay. When saliva has a normal, neutral pH, it helps neutralize plaque acids to reduce the risk of cavities.

But it’s not just bacteria that expose our teeth to acidic conditions—we do it ourselves with our choice of food and drink.

Acidic foods can directly lower the pH level in saliva. Lemon juice, for example, has a pH between 2 and 3. Red wine has a pH between 3 and 4. Blueberries? Around a 3.2. When the pH level in saliva becomes 5.5 or lower, the minerals in our teeth start to “demineralize,” or lose the minerals which keep enamel strong and intact—just the way enamel is demineralized by acids from plaque. This process is known as acid erosion.

Many of our favorite foods are acidic to some degree. Citrus and other fruits, pickled foods, vinegar, wine, coffee, tea—all of them can lower the optimal pH level of saliva. And sports drinks, energy drinks, and sodas? Check the labels and you’ll often find citric acid, phosphoric acid, and/or carbonation, all of which combine to create extremely erosive conditions.

So, no more soda? Or fruit? No. You don’t have to give up acidic foods altogether for healthy teeth. True, you won’t give up much eliminating soda from your diet. But fruits, vegetables, dairy foods, and meats are the source of essential vitamins, minerals, and proteins, and many of these healthy food choices have an acidic pH. How to eat nutritiously while protecting your enamel? Again, it’s a balancing act.

  • Enjoy acidic foods sparingly, or as part of a meal. Saliva can neutralize acids more effectively when they aren’t washing over your teeth all through the day.
  • Use a straw when you drink something with a low pH to reduce your enamel’s exposure to acids.
  • Balance high-acid foods with low-acid choices to help neutralize the acids in your diet. Add a banana to your blueberry smoothie. Pair your wine with some cheese.
  • Rinse with water after eating or drinking. When it comes to balanced pH, pure water is a 7.0 on the scale, a perfect neutral.
  • Chew sugarless gum to increase saliva production.
  • Use fluoride toothpaste—it not only helps prevent cavities, it helps remineralize teeth.

Even with your best efforts, acid erosion can be a problem. You might be experiencing enamel damage if you notice any of these symptoms:

  • Tooth pain or sensitivity.
  • Teeth that appear discolored. This happens as the whiter enamel thins, revealing the yellowish dentin underneath.
  • Changes in the shape of your enamel—your teeth become rounded or have little dents or pits, known as cupping.
  • White spots on your teeth, which could be a sign of demineralization.

If you think you could be suffering from enamel erosion, it’s a good idea to talk to Dr. Cosman, Dr. McDonough, Dr. Levac and Dr. Korcok when you visit our Kingston, ON office. We can diagnose conditions causing acid erosion, treat you if enamel damage has occurred, and offer suggestions for diet and eating habits to make sure your oral pH—and your dental health—is always in balance.
