Healthy Digestion Begins with Healthy Teeth

January 20th, 2026

You pay attention to what you eat. After all, your oral health depends on it. Without the necessary proteins, vitamins, and minerals in your diet, your teeth and gums will suffer. But did you know it’s a two-way street? Without healthy teeth and gums, your digestive system can suffer as well.

Because digestion doesn’t start in your stomach—it starts in your mouth! Let’s take a quick look at how the digestive system operates.

  • Teeth

The first step in digesting is breaking down foods so your body can extract their nutrients more easily. Healthy teeth are essential here. Incisors and canines tear food into smaller pieces while molars grind these pieces into an easy-to-swallow, paste-like consistency. While we chew, the surface area of the food increases, allowing the digestive enzymes in saliva, the stomach, and the small intestine to work more efficiently.

  • Salivary Glands

Saliva production increases when we eat. Digestive enzymes in saliva begin breaking down carbs into sugars, and separating fat molecules. Saliva also contains antimicrobial peptides which are important for oral and gut health.  

  • Esophagus

This muscular tube connects the back of the throat to the stomach. As we swallow, muscles in the esophagus contract and relax, an involuntary movement called peristalsis. These contractions push food down into the stomach. Peristalsis also occurs in the stomach and intestines, efficiently moving food through the rest of the digestive system. 

  • Stomach

Inside the stomach are gastric acids and enzymes which break food down further to help the small intestine make use of these nutrients in the next stage of digestion.

  • Small Intestine

This organ works to reap the benefits of our healthy diets. The small intestine absorbs about 95% of the nutrients from our digested food—carbohydrates, proteins, fat, vitamins, and minerals—and transfers these nutrients to the circulatory system to be used throughout the body. Any remaining food particles travel to the colon, or large intestine.

  • Large Intestine

Bacteria in the large intestine help process soluble fiber, which we can’t digest on our own. The large intestine is also where insoluble fiber and anything else undigested are converted to solid waste. 

Digestion begins in the mouth, and, when dental problems make chewing and swallowing difficult, the entire digestive system can be affected:

  • Uneven bite pressure

When you can’t apply chewing pressure because of decay, painful infections, or loose teeth, or when you are missing a tooth or teeth, it’s hard to chew food into the paste-like consistency necessary for rest of your system to process it smoothly.

  • Reduction in digestive enzymes and peptides

Saliva contains enzymes which make food easier to digest and antimicrobial peptides which are important for gut health. Xerostomia, or dry mouth, causes less saliva production. Inadequate chewing does as well. Without sufficient saliva, your system won’t benefit from the digestive prep work and gut protection which saliva typically provides. 

  • Uncomfortable swallowing

Insufficiently chewed food makes peristalsis in the throat and other digestive organs more difficult. Larger pieces of food can become stuck in the esophagus, causing painful swallowing or even choking. Dry mouth can also make swallowing very uncomfortable.

  • Higher risk of stomach problems

When food isn’t chewed thoroughly, the stomach has to work harder, and the risk of gastroesophageal reflux increases. Highly acidic gastric juices can back up into the esophagus and mouth, causing heartburn, chest pain, sore throat, and vomiting. 

  • Bowel irritation

When food particles are too large, the small intestine must work harder to break them down and to absorb their nutrients. Insufficiently digested food can upset the bacterial balance in the large intestine. These problems can cause indigestion, constipation, gas, and bloating.

  • Changes in nutrition 

Dental problems can also lead to nutritional imbalances even before we start to digest. Soft foods and liquids are often chosen over proteins, fruits, and vegetables when loose or missing teeth or painful teeth make chewing difficult. While a soft diet is fine for a few days if your mouth is a bit sore following dental treatment, it can be difficult to get the all the nutrients your body needs when you only eat soft foods.

Dentists generally recommend a thorough examination twice a year to discover and treat any oral problems before they become more serious, but any tooth pain or sensitivity is a good reason to see Dr. Cosman, Dr. McDonough, Dr. Levac and Dr. Korcok immediately. 

Whether you have a cavity, an infection, gum disease (one of the major causes of loose or missing teeth), bite problems, dry mouth, or any other dental concerns, the team at Cataraqui Dental Centre in Kingston, ON can help you discover solutions which will make eating and digesting your meals pain-free once again. Your healthy smile—and your healthy body—will thank you!

Find Out how Your Diet can Cause Cavities

January 14th, 2026

Sometimes food that’s good for your body isn’t necessarily the best for your teeth. Dr. Cosman, Dr. McDonough, Dr. Levac and Dr. Korcok and our team want you to know which healthy foods can harm your teeth and gums, and what steps you can take to continue enjoying these foods, even when you’re dieting.

When you begin to substitute empty calories with whole foods, make sure you also remember to focus on your dental health. The majority of people tend to switch out sugary foods in favor of fruits and vegetables when they diet.

It’s worth knowing that most fruits are highly acidic and composed of natural sugars. Some of the highly acidic fruits to watch out for include apples, grapes, strawberries, pineapples, blueberries, oranges, and grapefruit. Moderation is key here, as with all other things. Fruits can be a great source of energy to help you through your day, but try not to overdo them.

Often, people also incorporate more leafy greens into their diets, which mean plenty of salads. Salad dressing is another item you’ll want to watch out for. Many dressings are filled with vinegars and sweeteners that include harmful acids, which change the pH of your mouth. When your mouth shifts from alkaline to acidic, your smile also turns to a higher risk for erosion and decay.

Rather than get rid of these foods altogether, simply change what you do after you eat them. Rinse your mouth out with water, brush your teeth, or eat alkalizing foods after consuming these acidic foods. Healthy alkalizing foods include dairy products such as eggs and yogurt, or any type of vegetable.

If you have questions regarding your current diet and its effect on your oral health, please contact our Kingston, ON office and speak with a member of our staff. If you’ve begun to make changes in your diet toward a healthier lifestyle, we hope these tips can help your make positive changes to your oral health. Our team at Cataraqui Dental Centre wants a healthy lifestyle to be a top priority in your life.

Your Hard-Working Teeth

January 13th, 2026

Healthy teeth make you happy to share your smile with the world. But there’s more to your smile than its beauty! There’s a lot of hard work going on, as well.

Teeth Are Designed for Healthy Eating and Digestion

Because humans are omnivores, we can eat both meat and plants. That’s why our teeth have different shapes—they’re designed to help us process different types of food. 

  • Incisors, our front teeth, have sharpish edges to help cut through meats and other firm foods when we bite.
  • Canines, the pointed teeth, help tear food into bite-size portions.
  • Premolars are flat topped teeth with two cusps, raised points which help grind food.
  • Molars are the flat-topped teeth in the rear of the mouth. They have four cusps to grind and crush food into a paste-like consistency. 

So: Incisors and canines bite and tear food into smaller pieces, which molars and premolars then crush and grind into a paste. Bite, tear, crush, grind—why all this food aggression? Because that’s the key to healthy digestion! 

Chewing is the first step in digestion. Effective chewing:

  • Starts the process of breaking food down into digestible particles.
  • Increases saliva production. Saliva binds food particles so that we can swallow easily.
  • Expands the surface area of food particles, which allows the digestive system to extract nutrients more efficiently. 

When you’ve lost teeth or biting causes you pain, it can be hard to chew food as thoroughly as you should. Swallowing can be difficult. Digestion can suffer. In fact, healthy teeth are essential to healthy digestion. 

Teeth Have Other Important Jobs As Well

  • Speaking

Our teeth work with our tongues and lips to form many of the phonetic sounds which make up speech. Missing or misaligned teeth can affect speech development in children and pronunciation in children and adults.

  • Creating a Healthy Bite

To eat efficiently—and comfortably—we need a healthy bite. If your dentist or orthodontist has diagnosed a malocclusion, it means that your teeth don’t fit together properly because of misaligned teeth and/or jaws. Biting and chewing put hundreds of pounds of pressure on your teeth and jaws, and a bad bite can mean damaged teeth and painful jaw problems. 

  • Shaping the Face

Just like our bone structure, our teeth help give shape to our faces. Missing teeth can affect the appearance of chins, lips, and cheeks. Replacing lost teeth with dentures, bridges, or implants (which look and function like natural teeth) can restore facial symmetry.

Teeth Are Only Up to the Job with Your Help

You’re in charge! Daily brushing and flossing, eating a healthy diet, and regular visits to your dentist for exams and cleanings will help make sure your teeth are able to perform their many duties. 

If you’re experiencing tooth pain, if you have concerns about alignment, or if you’ve lost a tooth or teeth, talk to your dentist to learn how to get your teeth back to working their best for you—and be ready to share that beautiful, hard-working smile!

Natural Ways to Soothe a Toothache

January 7th, 2026

Toothaches can come in many different forms, but no matter which, they’re always uncomfortable. Dr. Cosman, Dr. McDonough, Dr. Levac and Dr. Korcok and our team want you to know there are simple ways to cure this common problem.

Toothaches can be caused by infections, gum diseases, teeth grinding, trauma, or having an abnormal bite. Several symptoms may become noticeable when you start to experience a toothache. You might develop a fever, have trouble swallowing, notice an unpleasant discharge, and most often feel lasting pain when you bite down.

If you begin to notice any of these symptoms, try to manage the pain with the simple remedies below. If the pain continues, contact our Kingston, ON office and schedule an appointment, because a bigger issue might be involved.

  1. First, try rinsing your mouth out with warm salt water. This helps to disinfect your mouth and may soothe the region where the toothache is occurring. Hydrogen peroxide can also help if you swish it around in your mouth.
  2. Applying a cold compress or ice pack to your jaw in area that hurts can help with swelling.
  3. Make sure to floss your entire mouth thoroughly. The problem could be caused by food debris stuck between your teeth.
  4. Certain essential oils possess pain-relieving qualities, including clove, nutmeg, eucalyptus, or peppermint oil. Use a cotton swab and dilute one of these oils, then apply it to the problem tooth and/or gum area. Repeat the process as needed. This can also be done with apple cider vinegar.
  5. Similar to essential oils, peppermint tea can soothe and slightly numb the area. Swish it around in your mouth once it has cooled off for temporary relief.
  6. You may also soothe a toothache by eating Greek yogurt. You might be surprised to know that yogurt contains healthy bacteria that can help fight against pain.
  7. Crushed garlic can be rubbed on the aching area to help relieve pain. Garlic contains allicin, which slows bacterial activity. The application may burn at first but it has been known to help treat inflammation.

When it comes to preventing toothaches, you can take various measures. Always make sure you brush and floss every day, though. If you schedule regular oral examinations by Dr. Cosman, Dr. McDonough, Dr. Levac and Dr. Korcok, you will decrease infections that may cause toothache from spreading.

If you’ve tried the methods listed above and your toothache hasn’t gone away, call our Kingston, ON office and we can schedule an appointment to figure out the cause of the problem and provide a solution.
