Which toothpaste should I use?

June 17th, 2026

Toothpastes come in many forms and boast different flavors, benefits, and endorsements. All are designed to remove surface bacteria and prevent the buildup of plaque that can cause tooth decay. With so many choices, Dr. Cosman, Dr. McDonough, Dr. Levac and Dr. Korcok and our team at Cataraqui Dental Centre know that selecting the right toothpaste can be intimidating. After all, some benefits are welcome bonuses, while others are absolutely essential. So how can you know which toothpaste is best for you?

CDA Seal of Recognition

While all toothpastes must first be approved by Health Canada’s Health Products and Food Branch for sale to consumers, the Canadian Dental Association puts these products through further rigorous tests for safety and effectiveness. Toothpaste that boasts the CDA Seal of Recognition can be trusted to do exactly what it claims.

Fluoridated

Fluoride is an essential ingredient in a daily toothpaste. It helps to protect the tooth from decay by removing plaque and strengthening the enamel. Although fluoride is found in many public water supplies, many people are deficient in it due to the consumption of bottled water instead of tap water. All toothpastes with the CDA Seal of Recognition contain fluoride.

Other benefits

If a toothpaste meets the CDA’s standards and contains fluoride, the next step is to clear it with your dentist. This is especially true if you decide to use a whitening toothpaste, which often contains abrasives to remove surface stains. Though abrasives are an effective aid in tooth whitening, they may not be recommended if you have weak tooth enamel.

Specialty toothpastes

In certain situations, Dr. Cosman, Dr. McDonough, Dr. Levac and Dr. Korcok may suggest or prescribe specialty toothpaste, depending on your oral health needs. For example, patients who are prone to tooth decay and cavities despite frequent brushing and flossing may benefit from prescription-strength fluoridated toothpaste to help prevent the weakening of tooth enamel. Others who suffer from tooth sensitivity may benefit from the use of desensitizing toothpaste. Talk with Dr. Cosman, Dr. McDonough, Dr. Levac and Dr. Korcok if you think a specialty toothpaste could be right for you by scheduling an appointment at our Kingston, ON office.

Shark Teeth

June 16th, 2026

It seems like sharks are everywhere these days—on land, sea, and air(waves). A halftime show meme gone viral. A week of summer TV devoted to our favorite apex predators. And who doesn’t have “Baby Shark” playing in their heads all day once they’ve heard it? But are we jumping the shark to discuss this topic in a dental blog?

Not at all! Because today, we’re going to talk about shark teeth—just not the ones you might be expecting.

One of the expected sights when a shark opens its mouth are those rows and rows of shiny shark teeth. Sharks can grow from two to 15 rows of teeth at any one time (and some sharks have even more). This means sharp new teeth are always ready to replace any shark tooth which is lost, broken, or worn out.

An unexpected sight? When children point to their new adult tooth or teeth coming in—right behind their still-firmly rooted baby teeth! This double set of teeth is called “shark teeth,” and, while it certainly might come as a surprise, it’s not all that uncommon. But why do children develop shark teeth at all?

After all, baby, or primary, teeth have small roots, and are designed to come out easily when the adult teeth start arriving. When a permanent tooth starts to erupt, it pushes against the root of the baby tooth above it. This pressure gradually dissolves the root of the primary tooth, and with nothing to anchor it, it’s now loose, wiggly, and ready to fall out. That’s why baby teeth often look like they have no roots at all when they eventually wiggle free.

Sometimes, though, the roots of a primary tooth don’t break down, which means baby teeth stay right where they are. It also means that the permanent teeth have to erupt somewhere else—usually behind those stubborn little baby teeth.

Shark teeth can first appear around the ages of five to seven when the permanent front teeth start arriving, or several years later, when the adult molars begin to come in. Any extra teeth in one small jaw naturally cause concerns about crowding and misalignment, especially when those extra teeth are molars. Fortunately, treatment is generally uncomplicated.

If the baby tooth is loose, time (and wiggling) might take care of the problem. But if the primary tooth or teeth just won’t budge, even after several weeks, it’s a good idea to schedule a visit with Dr. Cosman, Dr. McDonough, Dr. Levac and Dr. Korcok—especially if your child is experiencing pain or discomfort.

An extraction is often suggested when a baby tooth has overstayed its welcome. Because of its smaller root, extracting a primary tooth is usually a straightforward procedure. Dr. Cosman, Dr. McDonough, Dr. Levac and Dr. Korcok can let you know all the details, and can discuss sedation options if they’re appropriate for your child.

Whether baby teeth are left to fall out on their own, or given some assistance, most often your child’s permanent tooth will start moving to its proper position as soon as the space is available.

Unlike sharks, we don’t have an endless supply of replacement teeth, so it’s understandable to worry when you see anything unexpected. If you want to know more about shark teeth, or if you have any concerns, don’t hesitate to call our Kingston, ON office for expert advice.

What is a water pick and do I need one?

June 10th, 2026

Water picks, sometimes called “oral irrigators,” make an excellent addition to your regular home care regimen of brushing and flossing. Especially helpful to those who suffer from periodontal disease and those patients of ours undergoing orthodontic treatment with full-bracketed braces, water picks use powerful tiny bursts of water to dislodge food scraps, bacteria, and other debris nestled in the crevices of your mouth. Children undergoing orthodontic treatment may find using a water pick is beneficial if their toothbrush bristles tend to get caught on their wires or brackets.

When you use a water pick, you’re not only dislodging any particles or debris and bacteria you might have missed when brushing, you are also gently massaging the gums, which helps promote blood flow in the gums and keeps them healthy. While water picks are an excellent addition to your daily fight against gingivitis and other periodontal diseases, they are incapable of fully removing plaque, which is why Dr. Cosman, Dr. McDonough, Dr. Levac and Dr. Korcok and our team at Cataraqui Dental Centre want to remind you to keep brushing and flossing every day.

If you have sensitive teeth or gums and find it uncomfortable to floss daily, water picks are a good alternative to reduce discomfort while effectively cleaning between teeth. Diabetics sometimes prefer water picks to flossing because they don't cause bleeding of the gums, which can be a problem with floss. If you have a permanent bridge, crowns, or other dental restoration, you may find that a water pick helps you keep the area around the restorations clean.

So how do you choose the right water pick?

Water picks are available for home or portable use. The home versions tend to be larger and use standard electrical outlets, while portable models use batteries. Aside from the size difference, they work in the same manner, both using pulsating water streams. A more crucial difference between water picks is the ability to adjust the pressure. Most home models will let you choose from several pressure settings, depending on how sensitive your teeth and gums are. Most portable models have only one pressure setting. If you want to use mouthwash or a dental rinse in your water pick, check the label first; some models suggest using water only.

Please give us a call at our Kingston, ON office if you have any questions about water picks, or ask Dr. Cosman, Dr. McDonough, Dr. Levac and Dr. Korcok during your next visit!

Flossing Fact or Flossing Fiction?

June 9th, 2026

Somewhere in a bathroom drawer or medicine cabinet, we all have one—that little plastic dental floss dispenser. And whether you use your floss every day (yay!), or have completely forgotten it was in there (not so good), just how much do you know about that sturdy string? Let’s find out!

  • Flossing has been around for hundreds of years.

FACT: It’s been just over two hundred years since Dr. Levi Spear Parmly, a dentist in New Orleans, suggested his patients use waxed silk thread to clean between their teeth. This is considered the first “official” invention of dental floss, although using some form of tool to get rid of food particles between the teeth has been around since prehistoric times.

  • Brushing well is the same as flossing.

FICTION: It’s really not. While brushing does a great job of cleaning food particles, plaque, and bacteria from your enamel, there are some places those bristles can’t… quite… reach. Floss was designed to clean plaque and food from between the teeth and close to the gum line where your brush doesn’t fit.

  • There’s more than one way to clean between your teeth.

FACT: Indeed there is! Not only are there many varieties of dental floss (waxed, flavored, round, flat, thick, thin, in a dispenser, attached to miniature floss wands), but you have alternatives if using any kind of floss is difficult for you. Water-flossers direct a pulsing stream of water between and around the teeth and gum line to remove food particles and plaque. Another useful alternative is the interproximal brush, a tiny little cone-shaped brush designed to remove food and plaque from those hard-to-reach spots.

  • Flossing helps prevent gum disease.

FACT: Scientific studies haven’t provided definitive answers. But Dr. Cosman, Dr. McDonough, Dr. Levac and Dr. Korcok and our team strongly recommend daily flossing as one of the most important things you can do to prevent gum disease. Gingivitis, or mild gum disease, is caused by irritated, inflamed gum tissue. Gum tissue becomes irritated and inflamed as a response to the bacteria, plaque, and tartar, which stick to your teeth. Anything you can do to help remove these irritants will reduce your risk of gum disease.

  • Flossing helps prevent cavities.

FACT: We strongly recommend daily flossing to remove the food particles and plaque, which lead to cavities. Brushing removes cavity-causing plaque from the outer surfaces of your teeth. But there’s a lot of enamel between your teeth as well. Flossing removes plaque from these hidden spots, helping to prevent interproximal (“between the teeth”) cavities from forming.

  • Bleeding when you floss is normal.

FICTION: Bleeding isn’t a typical reaction to flossing. Bleeding gums could be an early sign of gum disease caused by plaque and tartar buildup. On the other hand, if you floss too hard, or go too deeply below the gum line, you can make delicate gum tissue bleed. Ask Dr. Cosman, Dr. McDonough, Dr. Levac and Dr. Korcok for tips on perfect flossing technique.

  • You need to floss after every meal.

FICTION: Dental professionals generally recommend brushing twice a day and flossing at least once each day. But this suggestion comes with some exceptions. If you have braces, your orthodontist might recommend flossing after eating. And certainly, for removing pesky food particles, flossing or interdental picks are a sensible choice after any meal.

  • Your dentist will never know that you haven’t been flossing.

FICTION: Nope. Sure, you can miss flossing a few times and catch up before your appointment at our Kingston, ON office. But built-up plaque between the teeth, red, swollen, or bleeding gums, and gingivitis and interproximal cavities let both you and Dr. Cosman, Dr. McDonough, Dr. Levac and Dr. Korcok know that you’ve been neglecting good dental habits.

  • It’s never too late to start flossing!

FACT: Flossing is a simple, quick, and inexpensive way to maintain tooth and gum health. If you haven’t had much luck flossing in the past, ask Dr. Cosman, Dr. McDonough, Dr. Levac and Dr. Korcok for flossing tools and techniques that will work for your specific needs. Start now, and see what a difference it will make at your next checkup!

If you had all these flossing facts at your fingertips, congratulations! But if you didn’t, no need to worry, because the real test of your knowledge is in its application. Flossing properly at least once each day will give you something far more rewarding than blog-quiz kudos—you’ll see that regular flossing rewarded with healthier teeth and gums!
