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.

Road Trip!

March 3rd, 2026

The bags are packed, the trunk is loaded, the route is programmed into your GPS, the playlist is set, and your destination awaits! Sometimes there’s just nothing more appealing than a road trip. So, to make your trip even more enjoyable, here are some dental tips to help keep you feeling clean and fresh over the long haul.

  • Fuel Up

If you’re bringing some road snacks, be sure to include a few that will help clean teeth and freshen breath. Packing a supply of bottled water helps you stay hydrated, washes away food particles, and eliminates the bad breath caused by dehydration. Carrots and apples are not only nutritious and tasty, they apply a bit of gentle scrubbing action to your enamel as you chew. Traditional travel favorites like granola bars, beef jerky, and chips tend to stick to the teeth and provide cavity-causing bacteria a leisurely feast, so enjoy them in moderation. (If you’re driving, save the snacks for a rest stop—not only is eating while driving prohibited in some areas, it’s a distraction you don’t need on the highway.)

  • Roadside Diners

The occasional sticky, sweet, or chewy indulgence is fine at home, but when you have hours in the car ahead of you, you might want to turn down the pecan pie, the giant pretzels, and the roadside sea salt caramels. Again, cavity-causing bacteria love sugars and simple carbs, and food that finds its way into tooth crevices finds its way onto their menu. And, it goes without saying, passing up garlic, onions, and spicy foods will help your mouth feel fresher longer—and make your travel companions happier.

  • Car Wash

Bring a travel-sized toothbrush and tube of toothpaste with you for a quick cleaning when you stop for a break. A ventilated case will keep your brush dry (bacteria like damp conditions) and away from questionable surfaces. Disposable mini-travel brushes are available that come with a bead of cleaner pre-loaded and ready to use—you don’t even need water for a cleaner mouth and fresher breath. Food particles do not make good travel buddies so don’t forget dental picks or floss. And if you can’t brush right away, try a rinse with water or chew a piece of sugarless gum. Sugar free gum can help stimulate saliva production, which is a good way to wash away food particles and neutralize acids in the mouth.

  • Roadside Repair

Even with the best preparation, accidents can happen. That’s why you have a spare tire and a lug wrench in your trunk. It pays to be prepared for a dental emergency on the road as well. There are dental travel kits available in stores and online, or create one for yourself. Along with your first aid kit, pack dental picks, antimicrobial wipes, sterile gauze, a mirror, and any other supplies you think might come in handy. If you wear braces or a retainer, be sure to include dental wax in case of an uncooperative wire, and a case to protect and keep track of your retainer. And it’s a good idea to keep our Kingston, ON office’s number on hand in case of emergency.

It’s a big country, and cruising the streets and highways is a wonderful way to explore it! But if you’re having any dental problems, be sure to see your dentist before taking off—after all your preparation, you don’t need a dental emergency to ruin your trip. Then, pack your bags, load your trunk, set your GPS, pick a playlist with something for everyone, and get ready to enjoy happy travels and healthy smiles!

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.
