So you might be wondering, just what are cavities? How do we get them? What do they do to our teeth? How can we prevent them? Let’s talk!

Our teeth need to be strong to bite and chew. That’s why they are protected by a coating called enamel, which is made up of very hard minerals. Enamel is the strongest part of our bodies—stronger even than our bones. But this doesn’t mean nothing can hurt it! And cavities, also called tooth decay, are one of the most common dangers facing our enamel.

So, what are cavities?

A cavity is a hole in your tooth enamel. If your tooth is not cleaned and repaired when a cavity is small, this hole can grow bigger until tooth decay reaches the inside of your tooth. Enamel doesn’t heal when it’s damaged, so you need to see a dentist to make your tooth healthy again.

How do we get cavities?

Bacteria are tiny little germs. Many kinds of bacteria live in our bodies, and some of them are quite helpful. The bacteria which cause cavities are not. These unhelpful bacteria join with our saliva and very small pieces of the food we’ve chewed to make a sticky film called plaque.

Like other living things, the bacteria in plaque need food. They get that food from the foods we eat, especially sugars and starches. As they eat, they change these sugars and starches into acids, and these acids attack the minerals which keep enamel hard and strong.

Because plaque sticks to our teeth, bacterial acids are able to make weak spots in enamel if the plaque isn’t brushed away. If you see a white spot on your tooth, that could mean that your enamel is losing minerals, and getting weaker.

What do cavities do to our teeth?

Over time, weak spots can grow bigger until there’s a hole in the enamel surface. If the cavity in your enamel is small, you might not notice it at first. But cavities can become wider and deeper, and even break through enamel to reach the inside of your tooth.

The inside of each tooth holds pulp, the part of your tooth which keeps it healthy. If tooth decay spreads to the pulp, it can cause more damage and infection, so it’s important to treat a cavity right away.

Dark spots on your enamel, a toothache, pain when you drink something hot or cold or when you bite down—these can be clues that you have a cavity, and you should visit us for an exam.

How can you prevent cavities?

Even better than treating a cavity is preventing one. Let’s make a list of some helpful do’s and don’ts for cavity prevention:

• Do: Feed yourself foods which are good for you.

Foods like milk and cheese and many dark green vegetables have lots of calcium and vitamin D to help keep your enamel strong.

• Don’t: Feed bacteria foods which are good for them.

Sugar and simple starches like potato chips are the kinds of foods bacteria like best, because they are easy to break down. This means more acids to attack your enamel.

This doesn’t mean you should never enjoy a treat! But eating lots of starchy snacks and drinking sugary sodas means more plaque, and more plaque can mean more cavities. If you’re eating something starchy or sweet, it’s a good idea to brush or rinse afterward.

• Do: Brush at least twice a day, for at least two minutes, with fluoride toothpaste.

This is the best way to get rid of plaque, which builds up every day. And fluoride toothpaste even helps make your enamel stronger.

• Don’t: Forget to floss.

Flossing takes a while to learn to do well, but it’s very important. Flossing helps prevent cavities between the teeth and near the gums.

• Do: Visit our Kingston, ON dental office for exams and cleanings.

Not only will we look for cavities, we’ll let you know the best way to brush and floss so you can get your teeth their cleanest.

• Don’t: Feel bad if you get a cavity!

Some people are more likely to get cavities than others, even when they brush just right and eat healthy foods. If you have a cavity, we can remove decay and repair your tooth with a filling.

And one last thing to do: talk to Dr. Cosman, Dr. McDonough, Dr. Levac and Dr. Korcok if you have any questions about the best ways to protect your teeth from cavities. We have lots of suggestions to help you take care of your healthy, beautiful smile!

Stress symptoms—which include high blood pressure, severe aches, and insomnia—may be affecting your health, even though you might not realize it. You may think illness is the culprit when in fact stress may actually be the reason. While stress can be good for us sometimes, Dr. Cosman, Dr. McDonough, Dr. Levac and Dr. Korcok and our team know stress can be physically harmful. But what is often overlooked is that stress can also take a toll on your mouth. Here’s how:

Teeth Grinding

It’s not uncommon for people dealing with stress to develop teeth grinding, also known as bruxism. People who grind their teeth at night may do so unconsciously, but the condition requires treatment to prevent the development of headaches, TMJ, and tooth damage. If you’re a night-grinder, talk to Dr. Cosman, Dr. McDonough, Dr. Levac and Dr. Korcok. We may recommend a night guard.

Mouth Sores

Research suggests stress and depression harm your immune system, making it easier for infections to develop and stick around. That can mean canker sores or a cold sore outbreak. If mouth sores are a recurring problem for you, give us a call to schedule an appointment with Dr. Cosman, Dr. McDonough, Dr. Levac and Dr. Korcok.

Bad Habits

Stress can lead to bad oral health habits such as smoking, drinking, and neglecting your daily brushing and flossing routine. If you’ve been feeling under pressure lately, try to keep up with your oral health routine—it will serve you well when your stress levels return to normal.

Dr. Cosman, Dr. McDonough, Dr. Levac and Dr. Korcok and our team at Cataraqui Dental Centre know there’s not always an easy way to reduce your stress levels, but eating healthy, exercising regularly, and spending time with friends and family are all good places to start.

Short answer: No. But, since an answer that short is hardly worth the time it took you to click on the link, allow us to explain further!

We tend to think of tooth decay as something we leave behind with childhood. And, while it’s true that youthful cavities are unfortunately common, older adults face unique challenges of their own which put them at risk for cavities.

Root Cavities

Gum tissue often recedes with age. And our roots, which were once completely covered and protected by gum tissue, become partially exposed to plaque, acidic foods, and the abrasive effects of heavy-handed brushing.

This is a problem. Instead of enamel, a substance called cementum covers and protects our roots. But cementum isn’t as strong as enamel, and so our roots are much more vulnerable to the cavity-causing bacteria in plaque, erosion from dietary acids, and damage caused by abrasive brushing. Root cavities also progress faster than crown cavities, which can mean a root canal procedure in your future, or, even worse, an extraction if a cavity isn’t treated promptly.

What can you do to avoid root cavities?

• Do what you do to avoid any cavity—brush at least twice a day for two minutes, use floss to clean between the teeth and along the gumline, and use a fluoride toothpaste.
• Fluoride treatments can be applied to the exposed root area for added protection. Ask your dentist about this option.
• Take care of your gum health. See Dr. Cosman, Dr. McDonough, Dr. Levac and Dr. Korcok regularly, and, if you have serious gum disease, a visit to your periodontist might be in order.
• Always use a soft toothbrush. Even a brush with medium bristles can be too firm for teeth and gums.

Failing Fillings

As we age, our dental restorations age as well. Over time, fillings can become loose, erode, or crack, which can lead to cavities under or around these damaged restorations. Bacteria can reach beneath a loose filling—your toothbrush can’t.

What can you do to prevent cavities in these hidden spots?

• Keep up with your dental checkups. Part of each dental exam is checking the condition of your dental restorations.
• Visit Cataraqui Dental Centre if you notice any sign of tooth decay, including tooth pain, sensitivity, or discoloration.
• If you discover a loose, cracked, or lost filling, even without any discomfort, call Dr. Cosman, Dr. McDonough, Dr. Levac and Dr. Korcok right away. A timely replacement filling can prevent hidden decay from seriously damaging a tooth.

Dry Mouth

Dry mouth, or xerostomia, occurs when our bodies don’t produce their normal amount of saliva. Saliva, of course, is vital for healthy and comfortable eating—it helps us swallow, digest, and taste our food. And it also has dental benefits! Saliva helps neutralize the acidic foods we eat, washes away food particles and bacteria, and contains minerals like calcium and phosphorus which remineralize tooth enamel.

Many medical conditions (including diabetes and high blood pressure), medical treatments (such as chemotherapy and radiation), and medications (both prescribed and over the counter) can reduce normal saliva production.

What can you do to restore saliva production?

• Drink fluids as recommended, especially water.
• Chew gum. Sugarless gum encourages saliva. Sucking on sugar-free candies works as well.
• Brush regularly with fluoride toothpaste, and ask about fluoride rinses.
• Talk to Dr. Cosman, Dr. McDonough, Dr. Levac and Dr. Korcok. There are medications available that can help.

Keeping up with our dental health is important at any age. Brushing and flossing, fluoride toothpaste, regular dental exams and cleanings at our Kingston, ON dental office—the basics of dental health don’t change over time, even if our dental challenges are a bit different as we get older. After all, do you ever outgrow an attractive, healthy smile? This answer is short and sweet: never.

They’re often mentioned together, and that’s understandable. After all, they’re the strongest parts of the body, they’re made of many of the same elements, they both require a diet rich in vitamins and minerals to stay healthy, a pirate flag wouldn’t be the same without them–so, what makes teeth and bones different? Glad you asked!

It’s Elementary

Teeth and bones are so strong because of their mineral composition. They have the highest concentration of calcium and phosphorus in the body, and these minerals combine to create sturdy structures which support our bodies, protect our organs, and help break down and digest our food. And they work well together—healthy teeth maintain jawbone density, and healthy jaws hold our teeth firmly in place.

But there are important differences in the anatomy of teeth and bones as well. Bones contain living cells, blood vessels, and nerves. They grow larger as we grow. As we age, old bone tissue breaks down and is constantly replaced with new bone tissue. This process enables our bones to stay strong throughout our lives. And bones heal.

When you break a bone, your body begins working right away to protect and heal the damaged area. Blood cells help with clotting around the break. After a few days, collagen proteins work to replace the clotted cells and form a soft callus. Within weeks, calcium phosphate deposits strengthen the collagen framework. Over time, the bone hardens and reshapes.

And while tooth enamel is the hardest substance in our bodies—harder even than bone—it is not indestructible. Our enamel is basically composed of minerals rather than living tissue, so it can’t regenerate. The enamel covering our teeth doesn’t replace cells as they age, and it can’t create new tooth cells if a tooth is injured through damage or decay. This means that a cracked or broken tooth can’t knit itself together, and enamel lost to decay won’t grow back.

Dr. Cosman, Dr. McDonough, Dr. Levac and Dr. Korcok can restore your smile with fillings, or crowns, or even implants if necessary, but preventing injury to your teeth is always best.

Protecting Teeth and Bones

You can make sure your teeth and bones are their safest and strongest by being proactive.

External bone injuries can be avoided with the use of proper safety equipment. Helmets, padding, work boots—if your work or play recommends protective gear, use it! Fortunately, there’s also protective gear for teeth.

• Helmets

Helmets not only protect against brain injury and concussion, they are often designed to protect the face, mouth, and jaw as well.

• Mouthguards

Mouthguards protect the teeth, lips, tongue, and jaw from damages caused by physical contact and falls. They’re available over-the-counter, or ask Dr. Cosman, Dr. McDonough, Dr. Levac and Dr. Korcok to fabricate a custom guard for the most comfortable and secure fit. A custom guard is an excellent option for people with braces, bridgework, or other dental appliances.

• Night Guards

Grinding and clenching the teeth at night can lead to loose and cracked teeth, headaches, jaw pain, and other unhappy consequences. Protect your teeth from the damage caused by bruxism (tooth grinding) by wearing a night guard.

Finally, one big difference between tooth and bone design: bones are safely hidden away inside the body, while our teeth are exposed to harmful plaque, bacteria, sugars, and acidic foods every day. Give your teeth the preventive care they deserve with twice-daily brushing, flossing, and regular visits to our Kingston, ON office. After all, your beautiful, healthy smile was never designed to be hidden!
