The World Health Organization defines oral health as being free of chronic mouth and facial pain, oral and throat cancer, oral sores, birth defects such as cleft lip and palate, periodontal disease, tooth decay and tooth loss, and other diseases and disorders that affect the mouth and oral cavity.

The Canadian Dental Hygiene Association (CDHA) defines oral health as the state of the mouth and associated structures being free from disease and, where future disease is inhibited, maintaining functions such as eating, talking, and smiling, contributing to overall health, well-being, and quality of life.

Oral disease

• Oral diseases are among the most prevalent chronic diseases.
• They include tooth decay and gum diseases that can lead to pain and tooth loss.
• Oral cancer leads to pain, tooth loss and premature death if not detected early on.
• Oral diseases, once considered localized infections, are now associated with other diseases such as diabetes, cardiovascular and respiratory diseases.
• Oral disease and pain can have a significant negative impact on your ability to learn, work, socialize, speak and eat foods that you need.

Did You Know?

• You can't be healthy without good oral health.
• Tooth decay is the most common disease of childhood; decay in children's primary teeth predicts future decay in adult teeth.
• Tooth decay can continue throughout your lifetime.
• In some areas in Canada, dental procedures under general anesthesia are the most common surgical procedures that children receive in hospitals.
• Canadians spend 13 billion dollars a year on oral health care, diseases, and injuries that are almost all preventable. In terms of costs associated with disease categories, oral health care follows cardiovascular disease and exceeds the costs for respiratory disease and cancer.
• Approximately 32% of Canadians have no dental insurance, and this percentage increases with age.
• If you smoke, drink alcohol excessively, or have diabetes, then your chances of developing gum disease are higher. Smoking, alcohol consumption and oral sex also increase your risk for oral cancer.
• Limited income and education are risk factors for high rates of oral disease.

What Can Each of Us Do?

• Public health solutions for oral diseases are most effective when they are integrated with other chronic diseases and with national public health programs .
