What are oral lesions?

An oral lesion (which includes aphtous ulcers) is an ulcer that occurs on the mucous membrane of the oral cavity. They are very common, occurring in association with many diseases and by many different mechanisms. They can be recognized by a break in the skin or mucous membrane with loss of surface tissue and the disintegration and necrosis of epithelial tissue.

The most common causes of oral lesions are localised trauma (i.e. rubbing from a sharp edge on a broken filling), infections, systemic conditions, associated dermatological diseases and recurrent aphtous ulcers (canker sores).

Oral lesions may form individually or multiple lesions may appear at the same time. Once formed, it may be maintained by inflammation and/or secondary infection. Rarely, an oral lesion that does not heal may be a sign of oral cancer.
