Message from the School of Dentistry

Your oral health is more important than you might realize The School of Dentistry is responsible for educating students who want to become oral health practitioners otherwise known as dentists and dental hygienists. It is also our responsibility to create awareness on the importance of oral health. Many people only see the dentist or dental hygienist when there is pain in the mouth which is often a sign that you waited too long. The human mouth is full of bacteria that can harm your mouth by forming a sticky layer called plaque on your teeth, causing damage to your teeth and gums. If left untreated oral health conditions can lead to other problems with your overall health. Inside this report, there are easy-to-read stories such as getting a simple head and neck examination during your regular dental check-up can be vital in detecting oral cancer early. We hope that these stories provide oral health guidance and insight.

Charcoal-based toothpaste can be more harmful to your teeth than beneficial warn dental hygienists. “It’s just another marketing fad,” says dental hygiene clinical associate professor Sally Lockwood. “There is no convincing scientific evidence to support the claims made by charcoal-based toothpaste. On the other hand charcoal is an abrasive material that can lead to the loss of luster and enamel of teeth.” Charcoal-based toothpaste claim to whiten teeth, help with bad breath, and absorb other bacteria in the mouth. “Charcoal-based toothpaste has become a fashionable marketing gimmick,” says Lockwood, adding the first documented use of charcoal on teeth was in the time of ancient Greece. “Again, none of these claims have been proven. I would not recommend this product to any of my patients.” Aside from damaging the tooth surface, Lockwood says charcoal toothpaste can damage gum tissue, root surfaces, tooth restorations, and leave particles behind in periodontal pockets. “One of the biggest concerns that come from using charcoal toothpaste is that they no longer have sufficient amounts of fluoride in them. Evidence suggests that charcoal in the toothpaste can absorb the fluoride, making it unavailable to the tooth and reducing the paste’s cavity fighting ability,” she says. “The claim is that charcoal toothpaste is antibacterial, antifungal and it will remove tooth stains. “But in reality, the charcoal absorbs the fluoride even before you use it and charcoal only helps remove surface stains not the intrinsic ones. This means you’re using a toothpaste without available fluoride and putting your teeth at risk.” Lockwood says to ensure you are not jeopardizing your oral health, seeking professional care from a dentist and dental hygienist for teeth whitening is recommended.

Standing in the toothbrush aisle surrounded by hundreds of choices, how do you know you’re choosing the right toothbrush? Do you go manual or electric? The choices can be daunting, but one general rule to keep in mind when searching for the correct toothbrush is to always choose one that has soft or extra-soft bristles says Nadia Kobagi, a dental hygiene clinical assistant professor at the School of Dentistry. “You can create irreversible gum damage if your brush bristles are too hard,” she says. “If you’re heavy-handed when you brush your teeth, you wear away the gum tissue which may lead to root exposure and sensitivity.” Kobagi says finding a toothbrush that fits your mouth is important as well. Ideally, your toothbrush should be large enough to be able to brush two teeth at a time.

ARE YOU USING THE

CORRECT

TOOTHBRUSH?

“People with smaller mouths need to look for a compact brush. Large toothbrushes can miss food and plaque buildup in tight spots,” she says. “Either manual or electric toothbrushes can be used. Both are effective if used correctly.” Battery-powered toothbrushes are not as researched as the electric ones says Kobagi. And people with dexterity problems should consider purchasing toothbrushes with modified handles that make them easier to grasp. It is recommended that everyone brush their teeth twice a day for two minutes using a fluoride containing toothpaste.

School of Dentistry. “Personally, I floss first but we just want to see that you are flossing.”

When it comes to flossing, there are many different types of floss’ to choose from. Here are a few to consider:

Traditional dental floss comes in either waxed or unwaxed form, both which are equally effective. Disposable floss picks are an easy to use alternative to traditional dental floss. They have a plastic handle with the floss across the top. You simply insert the floss between your teeth and when done throw it out. Non-disposable floss picks have a longer handle and floss head. You can purchase replacement floss heads for these. The non-disposable floss picks are ideal for people who have trouble flossing their back teeth.

The interdental brushes are easier to use for flossing over traditional thread floss. They have a thin bristled flossing head and do not need to be thrown out after each use. Water flossers or water picks use a stream of water to clean between your teeth. Water picks are ideal for people who don’t want to use traditional dental floss or have tight spaces between their teeth. 9

UNCONTROLLED diabetes

adversely affects gum health Many of us know diabetes is a leading cause

of heart disease and stroke. But what we fail to realize is that diabetes – especially if left uncontrolled – can adversely impact our oral health and increase your chances of getting periodontitis (or gum disease). Patients with undiagnosed and/or uncontrolled diabetes are more likely to develop a more severe form of periodontitis because of delayed wound healing and impaired immune response. Further, having untreated gum disease is also associated with significantly higher blood glucose levels in the body. “Patients with poorly controlled glucose levels suffer from periodontitis more often than those with controlled levels. Therefore, practicing good oral hygiene and maintaining healthy blood sugar level is key,” says Monica Gibson, periodontist and assistant professor at the School of Dentistry. “Patients who have uncontrolled diabetes respond less favorably to dental treatment. Elevated glucose levels lead to high levels of bad bacteria and decreases the healthy bacteria in the mouth. These bad bacteria make your mouth more susceptible to having periodontal tissues breakdown faster because your immunity is compromised.” Patients who have uncontrolled diabetes can show signs of delayed wound healing, mouth dryness, mouth ulcers, increased bone loss and increased severity of periodontitis. “Controlling diabetes within a normal range set by your physician goes a long way in keeping your gum health in check,” says Gibson. “Having any periodontitis issues treated also helps get your glucose tolerance under control. Get your sugar
