“What is the strongest substance in the body?” If this question comes up on trivia night, be prepared to impress your team when you confidently answer, “Tooth enamel!”

Tooth enamel? The reason for this surprising answer lies in the biology of our teeth. Minerals make up well over 90% of our enamel, a much higher percentage than is found anywhere else in the body, including our bones. But unlike bone tissue, which can heal and regenerate, tooth enamel cannot. Even though it is extremely strong, enamel can be damaged by a process called demineralization.

Demineralization

Demineralization is a result of acids at work in our mouths. Acids actually break down the minerals in our enamel, making the enamel softer. Over time, bacteria attack deeper into the tooth, eventually leading to decay. Acidic foods like sodas, citrus, pickles, and coffee are obvious culprits in providing an acidic environment, but there are other problem foods as well. We all have bacteria in our mouths, which can be helpful or harmful. The bacteria in plaque use the sugars and starches we eat to produce even more acids.

This process is something that takes place very quickly. In fact, even brushing too soon after eating something acidic can damage the demineralized surface of a tooth. Waiting at least 20 to 30 minutes to brush gives our bodies a chance to restore the enamel surface in a process called remineralization.

Remineralization

Our bodies are actually designed to help protect our enamel, and the most important part of this process is saliva production. Saliva cleanses our teeth and reduces levels of acidity. And our saliva constantly washes important minerals over our teeth. Calcium and phosphate ions rebuild and strengthen molecules where demineralization has taken place. This process is called remineralization.

We have other ways to help the remineralization process along. Fluoride toothpastes and fluoridated water speed up the movement of mineral building blocks back to the surface of the tooth. Fluoride also strengthens our teeth so that they resist acids and demineralization better than teeth without fluoride, making them less vulnerable to cavities.

New products are available for home and professional use that are designed to increase remineralization—talk to Drs. Tom Holmes, Gordon Lansdown, Karen Nesbitt, Nick Cosman, Brett Empringham, and Patrick McDonough at our Kingston, ON office if you would like the latest recommendations. In fact, talk to us about tooth-friendly menus, the best toothpastes, brushing techniques, and all the ways to keep your enamel its healthiest. You’ll be answering all those trivia questions with a strong, confident smile!

Decades ago, it was just expected that getting older meant losing teeth. But today’s dental practices and treatments help us defy expectations. How can we keep our teeth healthy as we age? Here are some great habits to continue or begin at any time of life:

• Brush and Floss Regularly

Brushing and flossing two minutes carefully twice a day is a habit we should never break. If using a manual toothbrush has become difficult, an electric model might be just what you need. We also have many suggestions if you have mobility or other issues, so please talk to Drs. Tom Holmes, Gordon Lansdown, Karen Nesbitt, Nick Cosman, Brett Empringham, and Patrick McDonough about making regular dental hygiene as comfortable and effective as possible.

• Keep Up with Exams and Cleanings

As we age, gum recession is common. This recession leaves the root areas of our teeth more exposed, and more vulnerable to cavities. Also, old fillings can break or loosen, and cavities can develop around their edges. Keeping a regular schedule of exams and cleanings at our Kingston, ON office helps us discover any problems before they become serious.

• Let Us Know about Changes in Your Health and Medications

If you are taking certain medications, you are at risk for developing a condition called dry mouth, where saliva production greatly decreases. Since saliva washes away the food particles that fuel bacteria growth, reduces acidic elements in the mouth that weaken enamel, and helps fight diseases, dry mouth sets the stage for increased chances of cavities and gum disease. If you are experiencing this condition, we have suggestions for hydration, dental rinses, and sugarless gums that can help.

• Prevent Gum Disease

Regular brushing, professional cleanings, and routine check-ups are the best way to keep your gums healthy. Since untreated gum disease is one of the leading causes of tooth loss in older adults, call us if you have any symptoms such as puffy, red, or swollen gums, bleeding, or persistent bad breath. We can treat periodontitis at any stage, but prevention is always best.

• Don’t Smoke

Studies show a link between smoking and the health of our teeth and gums, as well as a much greater risk of oral cancer. It is never too late to stop smoking! We have suggestions on ways to quit—please let us provide them.

Feel free to talk to us about any concerns you might have. With proper dental care, your teeth can last a lifetime. And that’s a great expectation!

When you were younger, and you brushed your teeth without any help for the first time, it was a big step. It meant you’d learned the right way to brush to keep your teeth and gums healthy. But why does brushing help keep you healthy? Let’s talk about plaque!

• What Is Plaque?

Plaque rhymes with “attack,” and that’s just what it does to your teeth. If you don’t brush for a few days (which is a bad idea!), plaque is the reason for that fuzziness you feel when you run your tongue over your teeth.

If your teeth feel fuzzy, that means that plaque has been building up for a while. But how does it begin?

Plaque is made up of saliva, bits of food, other liquids, and tiny little organisms called bacteria. While most of the bacteria in our bodies don’t bother us—and some even help us—the bacteria in plaque are not so helpful.

Plaque starts with a type of bacteria that stick to the teeth, loosely at first, and then more strongly. Within hours, they join with saliva, bits of food, and other bacteria and bacterial products to make a very sticky film. This film is plaque.

Why is it so important to brush plaque away every day? As Drs. Tom Holmes, Gordon Lansdown, Karen Nesbitt, Nick Cosman, Brett Empringham, and Patrick McDonough will tell you, plaque can cause cavities and hurt your gums.

• How Does Plaque Cause Cavities?

Bacteria are like us—they need food. The bacteria in plaque especially like the sugars we eat. (That’s why you shouldn’t have too much junk food or candy in your diet.) Bacteria change these sugary building blocks into a kind of acid, and because plaque is sticky, the acids stay on your teeth.

These acids breaks down the enamel, that hard coating which covers teeth. Tiny weak spots can grow and become holes in the enamel. We call these holes cavities, and your dentist can repair them by cleaning away the decay and putting a filling in your tooth to protect it.

But it’s best to prevent cavities from ever starting by brushing and flossing. Even though plaque is sticky, it is easy to brush away when you do it every day.

• How Does Plaque Hurt Your Gums?

The gums surround our teeth and help protect them, but they are also delicate. When plaque builds up, it can irritate your gums.

You might notice that your gums get red, feel sore when you brush, or look puffy. You might have bad breath that doesn’t go away. All these are signs that your gums are reacting to the plaque around them.

The good news is that careful brushing and flossing can usually fix these problems. Talk to Drs. Tom Holmes, Gordon Lansdown, Karen Nesbitt, Nick Cosman, Brett Empringham, and Patrick McDonough about taking good care of your gums.

• Can We Fight Plaque?

Yes! From the time you were small and learned how to brush, you’ve been learning how to fight plaque.

• Brush at least twice a day for two minutes, and be sure to brush all around each tooth and the gums.
• Floss to remove plaque from where it hides between the teeth and near the gums.
• Visit our Kingston, ON office for a cleaning, to remove plaque from hard-to-reach places and to learn the best ways to brush and floss.

As soon as you finish brushing, plaque starts to build up again. But no need to worry! Keep brushing, flossing, and visiting us for regular cleanings, and all your careful work will be rewarded will a beautiful, healthy smile.

We all want to live our healthiest lives. We know that part of keeping ourselves healthy is regular visits to our Kingston, ON office for checkups and necessary dental work. And that dental work might require an X-ray. Should the amount of radiation in an X-ray concern us?

First, it is helpful to know that the radiation you are exposed to from a dental X-ray is very small. A set of most bitewing X-rays, for example, produces an amount of exposure about equal to the amount of background radiation we get from our normal surroundings in a typical day. We also take care to minimize your exposure even further by using specially designed equipment and protective shielding, and taking only necessary X-rays. If your child is very young, if you are pregnant, or if you have other health concerns, talk to us about the advisability of X-rays and whether they are essential to treatment.

Second, much of our careful general examination will be done visually. Drs. Tom Holmes, Gordon Lansdown, Karen Nesbitt, Nick Cosman, Brett Empringham, and Patrick McDonough can check for cavities and other problems and assess tooth and gum health. But sometimes, there are conditions which can’t be detected without an X-ray.

• Decay that isn’t visible in an oral exam—if a small cavity develops between teeth, or is hidden underneath a filling, an X-ray will catch it before more damage can take place.
• Infection—An X-ray will reveal infections such as abscesses that can damage both bone and tooth, and gum disease that has harmed bone and connective tissue.
• Orthodontic and periodontal issues—We might need an X-ray to determine the spacing and development of your child’s incoming teeth and maturing jaw structure, to properly create braces for adults or children, or to place an implant within the jawbone.
• If you are a new patient, it is helpful to have complete X-rays taken as a baseline of your current dental health and previous dental work. This baseline allows us to track tooth and jaw development, if necessary, and to evaluate any future changes that might be a concern. (If you have had X-rays taken in another office, we can help you have them transferred so we have a background of your dental history.)

Even though the radiation from a dental X-ray is minimal, be assured that we will never request any unnecessary procedure. When we recommend an X-ray, we do so to make sure there is no decay or infection threatening the health of your gums and teeth, and that we have the essential knowledge we need to treat any dental, periodontal, or orthodontic condition. Because we all want to live our healthiest lives—and part of that healthy life is both active and proactive dental care.
