Top Five Dental Myths

August 27th, 2025

Sometimes the line between fact and fiction is easily blurred. This is certainly the case when it comes to dentistry, where myths and misconceptions abound. In a bid to put an end to health hoaxes, here are five dental myths to chew over.

Sugar Is the Number One Culprit of Tooth Decay

Sugar will rot your teeth. If you’re a parent, chances are you tell your children this every time they ask for something sweet. And chances are your parents told you the same thing. There’s no denying that sugar leads to cavity formation, but it's not the number one culprit of tooth decay. Sugar adds fuel to the fire, but it doesn’t light the match.

Going to the Dentist Is a Painful Experience

There are people who don’t go to the dentist because they think it’s going to be a painful experience. It’s time to put this myth to rest. New dental technology, developments in anesthetics and analgesics, and more conservative dental procedures have made visits to our Kingston, ON office a more comfortable experience.

Bad Breath Means You’re Not Brushing

Poor dental hygiene can cause bad breath, but it’s not the only thing that will leave you looking for a breath mint. There are many factors that can cause bad breath, including illness, acid reflux, medication, and dehydration. In addition, sometimes what you eat or drink can give you bad breath no matter how many times you brush and floss. Next time you order a sub for lunch, skip the onions and garlic.

Bleaching Products Weaken Teeth

Gels, pastes, strips — there are all sorts of products available to make our pearly whites even whiter. If used according to the directions, bleaching products are harmless. They do not affect the health or strength of the teeth, only the color. At the same time, too much bleaching can cause temporary tooth sensitivity or irritated gums; the enamel, however, is not weakened.

You Will Know When You Have Tooth Decay

This is the type of false information that can lead to serious dental problems. There are no early symptoms of tooth decay. By the time you experience pain, your tooth decay has led to nerve damage, which means your decay is advanced and extensive. The only way to know if you have tooth decay —and to prevent it — is to visit Dr. Cosman, Dr. McDonough, Dr. Levac and Dr. Korcok twice a year for a checkup and cleaning.

Don’t Let Craze Lines Faze You

August 26th, 2025

You’re getting ready for a night out, or you’re checking to make sure you removed every bit of spinach after eating, or you’re practicing your best selfie smile . . . and suddenly, you see something alarming in the mirror—tiny cracks in your tooth enamel! Is this a dental emergency?

Almost always, the answer will be no.  Cracks like this are most likely “craze lines,” and craze lines are not serious cracks in your teeth. These diminutive flaws are shallow vertical cracks in the enamel which don’t go all the way through the tooth and don’t affect the tooth’s structural integrity. Like the crazing on a piece of glazed pottery, these tiny cracks are superficial, and the only reason for concern is cosmetic.

  • Cause for Crazing?

Time and normal wear on our enamel are the most common culprits. Years of biting and chewing are stressful.

But you can help prevent additional craze lines by avoiding bad habits which can put external stress on your teeth: nail biting, knocking on teeth with oral jewelry, crunching down on ice cubes, using your teeth to open bottle caps—in fact, using teeth for anything other than chewing food.

Grinding your teeth is also hard on your enamel. If you suffer with bruxism (the medical term for tooth grinding), ask Dr. Cosman, Dr. McDonough, Dr. Levac and Dr. Korcok about a mouthguard or night guard. Eliminating the extra stress of unconscious grinding and clenching reduces the chances of craze lines. Even better, getting treated for bruxism can reduce the risk of serious pain and damage to your teeth and jaws.

  • Staining Can Make Craze Lines More Visible

Craze lines are often invisible unless the light is just right. However, you can make craze lines more noticeable if you drink coffee, tea, red wine, or dark sodas regularly. And if you need another reason to give up tobacco products, smoking, chewing, or any other use of tobacco can also darken craze lines.

Stains in craze lines don’t usually respond to brushing. You might be able to lighten stains with home or professional whitening. Ask Dr. Cosman, Dr. McDonough, Dr. Levac and Dr. Korcok for the options which are best for your staining.

  • Repairing Craze Lines

Don’t let tiny flaws keep you from smiling! If you are unhappy with the appearance of your enamel, talk to us about possible treatments, including bonding and porcelain veneers.

  • When It’s More Than a Craze Line

While a craze line is generally nothing to be concerned about, a deep line, or a line which is getting bigger, might suggest a crack in the tooth. Cracks need to be assessed and treated to avoid damage not only to the exterior of the tooth, but to the pulp of the interior as well.

How can you tell the difference? Craze lines are not painful; a cracked tooth might be. Sensitivity to hot and cold foods, painful chewing, gums swollen around a tooth, pain when you bite down, a crack that is getting larger—any of these symptoms could be a sign that you have a cracked tooth. These are reasons to visit our Kingston, ON dental office ASAP.

Craze lines might be medically harmless, but if they impact your confidence, that’s a problem. Our team can help you change habits that are causing craze lines, remove staining, or repair cosmetic damage. If you’re not crazy about those craze lines, ask us for solutions that will bring back your confidant smile.

Mamelons

August 20th, 2025

Quick trivia question: define “mamelon.” Some kind of warm blooded animal? No, not a member of the mammal clan, but good guess. A fruit of the gourd family? Nope! There are watermelons, and honeydew melons, and even canary melons, but no ma-melons. Those little rounded bumps you notice on the edge of your child’s permanent incisors when they first emerge? We have a winning answer!

  • Why Do We Have Mamelons?

We have eight incisors, or biting teeth, in the front of our mouths—four on top and four on bottom. Mamelons are actually a clue as to how these incisors were formed. Even before a baby is born, the permanent teeth begin to take shape. Three different groups of cells develop to form the incisal edge of these front teeth. As they fuse together, they create three lobes of enamel on the erupting edge of the tooth. It’s these lobes, or bumps, that give the teeth a serrated appearance.

Whether your child’s mamelons are quite prominent or barely noticeable, if you are worried about them, relax! They are almost always a temporary part of your child’s smile, and disappear over time with chewing and normal wear. But what if the mamelons overstay their welcome?

  • Cosmetic Concerns

Because mamelons are composed of enamel, without the underlying dentin layer found in the body of the tooth, they can appear translucent or a bit different in color. They might wear away unevenly, leaving the tooth edges looking misaligned. Or, they might not wear away at all if your child’s tooth eruption is delayed. Talk to Dr. Cosman, Dr. McDonough, Dr. Levac and Dr. Korcok if mamelons are a cosmetic concern for you or your child. You might discover that they are wearing away naturally, or we can discuss ways to polish or smooth them down if needed. This is a painless procedure that doesn’t require an anesthetic. Generally, however, this is a matter where time will resolve the issue for you.

  • Orthodontic Implications

Occasionally, mamelons might become a topic of discussion for orthodontic reasons. Sometimes, mamelons do not wear away over time because of a malocclusion (misaligned bite). Your orthodontist will let you know your child has a bite problem and can explain treatment options. Your orthodontist might also suggest smoothing away the mamelons to ensure that the edges of the incisors align correctly and symmetrically while the teeth are in the process of straightening. Again, this is not always considered a necessity, so weigh your options with your dental care provider.

So, if you notice that your child’s beautiful new teeth are bumpy or serrated as they erupt, don’t be concerned! If you have any questions about mamelons, talk to Dr. Cosman, Dr. McDonough, Dr. Levac and Dr. Korcok at your next visit to our Kingston, ON office. This is a natural occurrence and most likely just a temporary “bump” in the road. Soon enough, mamelons will be a memory—and the answer to a pretty difficult trivia question.

Could a Night Guard Be the Answer to Your Dreams?

August 19th, 2025

Have you been having trouble getting a good night’s rest?

Sometimes the reason for a poor night’s sleep is obvious. A midnight horror movie. A bedtime espresso. That anchovy and pineapple pizza you had for dinner. Not much we can do about these problems.

Sometimes, though, the cause of your sleep difficulties is dental in origin, and that is something Dr. Cosman, Dr. McDonough, Dr. Levac and Dr. Korcok can help with.

Teeth grinding, or bruxism, is a very common dental problem. When people with this condition sleep, their jaws clench and their teeth grind against each other throughout the night. When to suspect you might suffer from bruxism?

  • You wake with a sore jaw, or you hear pops or clicks when you move your jaw
  • You suffer from frequent headaches or facial pain
  • Your teeth are chipped, cracked, flattened, worn down, or sensitive
  • You wake up tired, because grinding affects the quality of your sleep
  • Partners, siblings, or roommates complain about nocturnal grinding noises affecting the quality of their

Pain and fatigue are unpleasant enough, but there are additional serious consequences for those who suffer from bruxism. Our jaws are extremely powerful, and clenching and grinding can put hundreds of pounds on pressure on teeth and jaws over hours of sleep. These forces can lead to:

  • Damaged teeth. Cracked, chipped, and worn down teeth can mean veneers, crowns, and root canals. Seriously compromised or broken teeth might need to be extracted.
  • Damaged dental work. Bruxism can lead to fractured veneers and damaged fillings and crowns. If the damage is too serious for repair, replacement might be necessary.
  • Damaged jaw joints. Severe cases of bruxism can lead to injury to the temporomandibular joint, or TMJ, the complex hinge that allows our jaws to move up and down, back and forth, and side to side.

While these problems can be treated with restorations, or root canals, or implants, or surgical procedures, prevention is clearly a much better option for a healthy smile. And one of the simplest and most effective treatments for preventing the damage caused by bruxism is a night guard.

Night guards fit over the affected teeth to prevent them from touching directly, saving tooth and enamel from injury and wear. Not only do night guards prevent contact, they spread the biting forces of the jaw over the surface of the guard to greatly reduce their impact. And because they also stop the jaw muscles from clenching tightly, there’s no excess stress placed on the temporomandibular joint.

While over-the-counter products are available, it’s best to see Dr. Cosman, Dr. McDonough, Dr. Levac and Dr. Korcok for the most effective night guard. A custom night guard is designed to fit your individual teeth and mouth perfectly. Impressions or 3D scans are taken in our Kingston, ON office, and a guard is fabricated with the precise shape, strength, and thickness you need to protect your teeth. And, as a bonus, custom night guards offer the most comfortable fit for the most comfortable night’s sleep.

Scary movies, late night caffeinating, creative food combinations—not much we can do about those! But if you’re suffering lost sleep and painful mornings because of tooth grinding, give us a call. A night guard just might be the key to sweet dreams.
