Today, during the 85th General Session of the International Association for Dental Research, scientists are reporting that they have developed a method for the effective healing of, and relief of pain associated with, canker sores. Canker sores (scientifically known as aphthous ulcers) are painful recurring ulcers inside the mouth that afflict 60 million Americans. They are not viral or contagious. The most common form, called minor aphthous ulcers, are less than 10 mm in diameter and typically heal within 10-14 days. The direct cause of canker sores is unknown, but studies have shown that stress, family history, and cuts in the mouth (like those caused by braces or accidental bites) are indirect causes. Diet may be a factor for some people as well, though specific triggering foods have not been identified. There are no significant complications caused by unhealed canker sores, but the acute mouth pain can interfere with the ability to eat, drink, or speak and impair the sufferer’s quality of life.
