What causes canker sores?

Canker sores, medically termed “aphthous ulcers”, are very common. They develop suddenly on the tongue, sides of the mouth, or gums and result in the destruction of the protective lining of the mouth. You can recognize a canker sore; it is ray and open, with a whitish yellow base. Contact with acidic, spicy, or salty foods is usually painful. It is not known why people get canker sores. Heredity may play a part, since canker sores often run in families. Occasionally, certain foods, such as peanuts, may trigger an attack of canker sores. Most canker sores appear without known reason. Canker sores are usually a small, occasional nuisance. However, some persons get large painful canker sores which may occur more frequently. Probably, the most common cause of canker sores is mild trauma to the mucosal surfaces of the mouth, producing a small cut and resulting inflammatory reaction. Canker sores are not contagious.
