The grownups in your life encourage you to brush and floss, eat healthy foods, and visit us in the dental office for exams and cleanings. Why? Because we all want to help you prevent cavities.

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 that 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 that 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, which 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 that 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 that 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 that 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 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. We even have special coatings called sealants that can protect your teeth from plaque.

• 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 Drs. Tom Holmes, Gordon Lansdown, Karen Nesbitt, Nick Cosman, Brett Empringham, and Patrick McDonough 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!

At Cataraqui Dental Centre, we know many people have experienced some form of mouth sores or irritation. Some mouth sores are harmless and go away on their own after a few days, while others are more serious and should not be ignored. Mouth sores occur for many different reasons, but bacterial infections, viruses, or funguses often trigger them. The best way to tell the difference between a canker sore and a cold sore is that canker sores occur inside the mouth while cold sores occur on the outside the mouth.

The most common mouth sores are:

Canker sores: A non-contagious, small, grayish ulcer with a red border, canker sores appear inside the mouth. While outside factors such as stress, fatigue, or allergies may increase the chances of developing a canker sore, most health experts believe they stem from bacteria or a virus that attacks the immune system. Canker sores typically heal within a week or two.

Cold sores: Also called fever blisters, cold sores are contagious groups of fluid-filled blisters that often erupt around the lips and sometimes under the nose or around the chin. Cold sores are the result of the herpes simplex virus, and once infected, the virus remains in the person’s blood stream.

Leukoplakia: A potential warning sign of oral cancer, leukoplakia is a premalignant lesion that appears as a white patch on the inside of the mouth, tongue, or gums. The lesions, which are caused by excessive cell growth, usually afflict those who smoke tobacco. Drs. Tom Holmes, Gordon Lansdown, Karen Nesbitt, Nick Cosman, Brett Empringham, and Patrick McDonough may choose to have the lesion biopsied if the outbreak appears severe.

Oral candidiasis: Also called oral thrush or moniliasis, this condition is caused by the overgrowth of a type of yeast called candida. Common symptoms of oral candidiasis include white spots inside the mouth and on the tongue, redness or discomfort in the mouth area, sore throat,difficulty swallowing, and cracking at the corners of the mouth. It is important to visit Drs. Tom Holmes, Gordon Lansdown, Karen Nesbitt, Nick Cosman, Brett Empringham, and Patrick McDonough if you have oral candidiasis. If left untreated, it may infect your bloodstream, which can be very dangerous. Healthy adults do not usually get thrush, and the condition is most often seen in infants, the elderly, patients undergoing chemotherapy, or people with AIDS or other diseases that are known to weaken the immune system.

Should you have a mouth sore that lasts a week or longer, we encourage you to give us a call and schedule an examination at our Kingston, ON office.

You may have heard this term the first time you or a friend got your wisdom teeth. That makes sense, as wisdom teeth are the teeth most often impacted in teenagers and young adults. But other permanent teeth can be impacted as well. What exactly do we mean by “impacted teeth,” and what can we do to treat them?

The term “impacted” means that somehow a tooth has been blocked from erupting properly. A tooth may be completely blocked by another tooth, erupt in the wrong space, or even come in from the wrong direction. Depending on the teeth involved, there are several different options for treatment.

From Baby Teeth to Permanent Teeth

Normally, when children lose a baby tooth, a permanent tooth is right there, ready to take its place. But teeth don’t always behave according to plan. Occasionally, that baby tooth just won’t budge, and the permanent tooth starts to erupt behind it. When this happens, a simple baby tooth extraction will often let the permanent tooth move into its proper position on schedule.

A more complicated situation develops when upper teeth are impacted because there isn’t enough space in the mouth for them. In this case, a device called a palatal expander might be used to gradually widen the upper jaw to allow the permanent teeth to erupt without crowding.

In other rare cases, a tooth (often the canine) fails to erupt and may require oral surgery to uncover it, followed by orthodontic treatment to guide it into position.

Impacted teeth can result from other causes as well, and every impacted tooth should be treated as quickly as possible. Left untreated, the teeth can fail to erupt at all or erupt in the wrong place, crowd other permanent teeth, damage the roots of the teeth near them, and lead to difficulties eating and dental pain.

Wisdom teeth

Wisdom teeth are often a problem because there is simply not enough room in the jaw for them.

Wisdom teeth that are completely impacted (still in the jawbone) can sometimes be left alone if they aren’t causing other problems. But if impacted wisdom teeth develop cysts, affect the teeth around them, or lead to other dental complications, they should be extracted.

Partially erupted teeth, those that have begun to emerge through the gums but don’t erupt fully, can be the source of different gum and tooth problems. Because the gum tissue overlaps the tooth, food particles and bacteria can become trapped, leading to rapid tooth decay and even infection. In this case, extraction is probably the best option.

Be Proactive

The term “impacted” actually comes from the Latin root meaning “pushed against.” But teeth that don’t erupt at the right time, in the right place, can have a different kind of impact on dental health and appearance. And the earlier we can catch these problems, the easier it is to treat them.

Regular exams and X-rays with Drs. Tom Holmes, Gordon Lansdown, Karen Nesbitt, Nick Cosman, Brett Empringham, and Patrick McDonough at our Kingston, ON office will show the progress of the teeth even before they erupt, and if there will be the space for them to fit in the mouth properly. We may recommend a visit to the orthodontist by the age of seven to see if there are any signs of potential orthodontic problems.

Intervention at an early stage can prevent potential problems from becoming major ones. That is why it’s so important to be proactive when teeth are erupting in children and young adults. After all, a healthy, confident smile makes a real impact!

Whew! It’s a hot one! And whenever the temperature soars, you need to stay hydrated, especially when you’re outside or exercising. But all cold drinks aren’t equal when it comes to healthy hydration. Which beverages shouldn’t have a prime spot in your cooler when you’re wearing braces or aligners?

• Soft Drinks

You’re probably not surprised to find soft drinks at the top of the list. After all, sugar is a) a big part of what makes soda so popular, and b) not a healthy choice for your teeth.

Sugar is a favorite food source for the oral bacteria that make up plaque. These bacteria convert sugar into acids, and these acids attack the surface of your tooth enamel. Over time, the minerals which keep enamel strong begin to erode, and weakened, eroded enamel is a lot more susceptible to cavities.

So, what about sugar-free drinks? Does this make soft drinks a better choice? Unfortunately, you can take the sugar out of many sodas, but you can’t take the acids out. Most soft drinks are very acidic, even without sugar, and will cause enamel erosion just like the acids created by bacteria will.

• Fruit Drinks

Fruit juice provides us with vitamins, which is great, but it’s also full of natural sugars and acids. And blended fruit drinks and fruit punches often contain added sugars and added citric acids. Best to choose 100% fruit content and check the labels before you buy. (And you can always get refreshing fruit flavor by adding a slice of fruit to a glass of water.)

• Sports Drinks

You might be surprised to see these on the list—after all, they promise healthy hydration while you’re working out. And hydration is healthy—but sugars and acids aren’t. Even when the label tells you there’s no added sugar, that same label will often reveal high amounts of citric acid. In fact, some sports drinks are more acidic than sodas.

We’ll make an exception, though, for thirsty people who participate in sports or activities that require a lot of physical exercise and produce a lot of sweat. When we sweat, we lose electrolytes, those ionized minerals which help regulate many vital bodily functions. Talk to Drs. Tom Holmes, Gordon Lansdown, Karen Nesbitt, Nick Cosman, Brett Empringham, and Patrick McDonough about which sports drinks are best for you if you need to replenish your electrolytes when working out.

So, what’s your best hydration choice on a hot day? Water! It not only hydrates you, it cleans your teeth, it helps you produce saliva, and it often contains tooth-strengthening fluoride. But if you only have sports drinks in the cooler, or if you just want to enjoy a soft drink or a bottle of juice from time to time, no need to go thirsty. We have some ways to make sure your teeth are safer, even with this tricky trio:

• Rinse with water after you drink a sugary or acidic drink. And remember to brush when you get home.
• Be choosy. Check labels for added sugars and acids.
• Don’t sip your drinks all day long. Saliva actually helps neutralize acids in the mouth, but sipping acidic beverages throughout the day doesn’t give saliva a chance to work.
• Use a straw to avoid washing your enamel in sugars and acids.

You need to keep hydrated when it’s hot. When you’re packing your cooler, choose drinks that are healthy for your entire body, including your teeth and gums. Ask our Kingston, ON team for the best choices in cold drinks to make sure you’re getting the hydration you need—without the sugar and acids you don’t!
