Your oral health and the pandemic

Maintaining your oral health regimen, even during the pandemic, is important to your overall health.

As regulated health-care professionals, dental hygienists must follow stringent rules and uphold standards set by their regulatory college (College of Dental Hygienists of Ontario) to ensure the public receives safe and ongoing comprehensive oral care – at all times, even during the pandemic.

If you have any questions about your oral health care visit, speak to your dental hygienist. They will be able to provide information in response to your inquiries and put you at ease, so you can be confident receiving safe oral health care at your next appointment.

Why you shouldn’t ignore bleeding gums.

75%...of adults*
may suffer from some sort of gum disease.

*over the age of 30

Bleeding gums indicate trouble and ignoring them could put you at risk for other illnesses such as heart disease, stroke, respiratory disorders, and premature or low birth-weight babies. Oral infection can also affect blood sugar levels, making it difficult to control diabetes.

Over time, a buildup of bacteria collects at the gum line as plaque, and if not removed on a daily basis eventually hardens on the teeth forming calculus or tartar. If left untreated, infective bacteria can enter the bloodstream from the gums and travel to other parts of the body potentially causing other types of health problems.

Fortunately, with regular and proper oral care, gum disease can be controlled or even reversed. Professional dental hygiene services can remove tartar and help control bacteria. Remember, your dental hygienist can help you take action before the condition become serious.

Fact Sheets


Health researchers have been interested in the latest phenomenon of electronic cigarettes (e-cigarettes) where users inhale aerosol instead of smoking. An e-cigarette is a battery-operated device that heats a liquid into an aerosol the user inhales. The liquid usually contains flavourings in it, along with other additives. The use and availability of e-cigarettes has increased across the world, and a number of traditional cigarette manufacturers now sell e-cigarettes.

Nutrition and Oral Health 

A well-balanced nutritious diet is important for good oral health and general health. The food we eat supplies the nutrients that the body, bones, teeth and gums need to renew tissues and help fight infection and disease, including periodontal (gum) disease. Dental hygienists work with their clients to promote good overall health by keeping the mouth and body healthy with preventive oral care treatment and nutrition counselling.

Tooth Decay

Dental caries, also known as a cavity or tooth decay, is a common disease of children as well as adults. Although there have been notable declines in tooth decay over the past three decades, it remains the most common chronic childhood disease, more widespread than asthma by at least five times. For adults, nine out of 10 over the age of 20 have some degree of tooth decay. Proper oral hygiene and nutrition are necessary to prevent cavities.
