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


Years ago, corrective orthodontic appliances, known as braces, were used only for pre-teens and teens having problems with their bite. Today, according to recent statistics, close to 30 per cent of ortho clients are adults. Despite this growing trend toward adult orthodontics, it pays to start orthodontic treatment early for maximum effectiveness. Some dental professionals recommend children receive an orthodontic evaluation by age seven.   






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.
