My toothbrush did what?

September 23rd, 2026

If you were to put your toothbrush bristles under a high-powered microscope, what you would see might give you nightmares: millions of bacteria, busily crawling up and down your toothbrush bristles, consuming proteins that came from your mouth, and still clinging to the bristles even after you’ve rinsed them with water.

Rinsing your toothbrush after brushing removes some of those ferociously hungry bacteria, but not all. The Canadian Dental Association says that bacterial infestations develop on toothbrushes within a month of daily use. The CDA also states that unless a toothbrush is sterilized before being packaged, it’s going to come with bacteria – free of charge!

Germs and Frayed Bristles: the Demise of a Toothbrush

Dr. Cosman, Dr. McDonough, Dr. Levac and Dr. Korcok and our staff recommend that you toss your old toothbrush in the trash and purchase a new one every three months. Children tend to bite on their toothbrushes, which makes the bristles degrade and fray faster. Chances are kids may need to have their toothbrushes changed more frequently.

Where do they hide?

Bacteria are tenacious little germs that head for those concealed areas between toothbrush bristles. They are highly adaptable and exist in every type of extreme environment. Some people actually go so far as to put their toothbrush in a microwave for a few seconds to kill germs, but this doesn't always work either. In fact, you may only end up with a toothbrush that’s as bendable as a Gumby doll – and still covered with germs.

Feed a Cold, Starve a Fever, and Get Rid of Your Toothbrush

When you have a head cold, your mouth is teeming with bacteria gleefully roaming around, and gobbling mucus and dead skin cells. If you brush your teeth while suffering a sinus condition, the brush will act like a magnet for ravenous bacteria. Use your old toothbrush while you are sick, but as soon as you feel better, throw it away and get a new one. Otherwise you could possibly re-infect yourself with the same cold germs!

Sleep Apnea: What a Dentist Can Do

August 5th, 2026

You find yourself drowsy and irritable all day. Or you have trouble sleeping, and when you do, you snore loudly throughout the night punctuated with silent pauses where you aren’t breathing at all. Or your loved ones tell you that you’ve been keeping them awake with your snoring or frightening them awake when you gasp for breath. Whatever symptom may have brought you to the doctor, you’ve been diagnosed with obstructive sleep apnea, and now it’s time to get this sleep disorder under control.

Obstructive sleep apnea occurs when the tissue in the back of the throat relaxes, partially blocking the airway, or structural problems in the mouth and throat (such as enlarged tonsils or tongue) obstruct air flow. The tissue around the air passage vibrates with every breath causing those annoying snoring sounds. More dangerous, an obstructed airway means that there is not enough oxygen getting into the lungs. The struggle to breathe wakes us, interrupting the deep sleep we need to function. Untreated, the results of sleep apnea can range from drowsiness and irritability to a greater risk of high blood pressure, heart disease, and stroke. Luckily, there are several approaches to combatting this form of sleep apnea, including life style changes, surgery or breathing machines, and orthodontic appliances.

  • Lifestyle Changes

Sleep apnea is more likely to affect those who are overweight, smoke, use alcohol, take certain medications, or sleep on their backs. If you can make changes in your lifestyle that will restore the quality of your sleep, this is a great first option.

  • Surgery or Breathing Machines

Sometimes obstruction of the airway is caused by structural problems in the throat or mouth. Tissue can be reshaped or removed during surgery to widen and stabilize the breathing passage. Or you might be prescribed a machine such as a CPAP (continuous positive airway pressure) machine, which blows pressurized air through a tube and mask to keep the airway open during sleep.

  • Oral Appliances

Dr. Cosman, Dr. McDonough, Dr. Levac and Dr. Korcok can also be an important resource if you struggle with obstructive sleep apnea. Many people suffering from this disorder prefer an oral appliance for its effectiveness, comfort, and convenience. One common oral sleep appliance is designed to support your lower jaw in a forward position. This jaw movement increases the open space of your airway as you sleep. Other appliances can prevent the tongue from blocking the airway and obstructing air flow. These appliances resemble mouthguards and retainers, and, like them, are custom made just for you. We will recommend the type of appliance best suited to your needs, and will take a model of your mouth and teeth so that a lab can craft an appliance that will be a perfect fit. We will adjust it for comfort if necessary, instruct you on its use and care, and schedule follow up treatment to make sure the appliance is treating your sleep apnea as efficiently as possible.

Whether you opt for a change of lifestyle habits, a CPAP machine, surgery, or an oral appliance, it is important that you treat this sleeping disorder. Left untreated, obstructive sleep apnea can have many serious consequences. If you suspect you might have sleep apnea, talk to us during your next visit at our Kingston, ON office. You deserve a good—and healthy—night’s sleep.

Sunbeams and Beaming Smiles

August 4th, 2026

Long days in the sun’s rays offer you lots of options for outdoor activities. Beach time? Vacation? Open-air concerts? Baseball, biking, board sports? No matter what plans you have for these sunny days in Kingston, ON, we have some tips to keep your smile beaming.

Use Sunscreen

Sunscreen is good for all ages and skin tones, and it’s also designed to protect your smile. Lip tissue is thin and delicate, and can easily be damaged by the ultraviolet rays which cause skin cancer and premature aging. 

If your regular sunscreen isn’t suitable for your lips, there are many protective lip balms designed especially for your smile.

  • Make sure you get the proper level of protection. Dermatologists recommend lip balms with a minimum SPF (Sun Protection Factor) of 30.
  • Reapply at least every two hours, and sooner if your lips get wet or if you’re eating or drinking.

Protect Your Smile with a Mouthguard

Mouthguards help protect your teeth from damage caused by impact, whether from hard surfaces or hard elbows! Any time there’s a chance of a fall or a collision, a mouthguard is a good idea. Use your guard for:

  • Biking, in-line skating, skateboarding, or any activity where an unexpected fall is possible 
  • Contact or low-contact sports like baseball, basketball, and soccer, where bodies collide with equipment or other bodies

If you play organized sports, you might already own a mouthguard. If not, talk to Dr. Cosman, Dr. McDonough, Dr. Levac and Dr. Korcok about over-the-counter options or a custom-fitted model. And if you wear braces, no need to stay indoors! There are mouthguards designed to protect your teeth, cheeks, lips, and braces. Ask the team at Cataraqui Dental Centre for recommendations.

Hydrate

On hot days, our brains help regulate our body temperature. How? By sending the signal to start sweating! Some heat is transferred from our bodies to evaporate perspiration, which helps cool the skin. But that cooling perspiration comes at a cost—the water we lose through sweat can lead to dehydration. 

Water is essential for our health, and especially when it’s scorching outside. Drinking water throughout the day is healthier than drinking lots of water at one time, and your doctor can let you know the right amount of water for your body, since we’re not all built the same. A bottle of water doesn’t contain artificial ingredients, caffeine, or sugars, so it’s a great, healthy outdoor companion. 

More? Water is also great for your smile!

  • Water washes food particles and bacteria away from teeth and gums for fresher breath and a healthier mouth.
  • Most communities add fluoride to their water, and fluoride strengthens tooth enamel to help you fight cavities. If your local water supply isn’t fluoridated, talk to your dentist about other treatments which can provide fluoride’s cavity protection.
  • Hydrating helps prevent dry mouth. Normal saliva production doesn’t just keep the mouth moist for eating and speaking—it also protects our teeth and gums as it washes away food particles and helps counteract excess acidity in the mouth.

It’s easy to get distracted with summer activities and vacations—after all, they’re designed to be distracting! But don’t let your well-deserved fun in the sun distract you from your regular dental care. 

Regular dental exams catch small problems before they become larger ones, and cleanings make sure your smile is bright all summer long. If you’re overdue for a visit to Cataraqui Dental Centre, make room in your schedule for a checkup.

Summer can be a time to relax, renew, and recharge. While you’re enjoying those extra hours of sun, take care of your oral health for a beaming smile which will look great on you any time of year!
