Canker sore is a type of mouth ulcer. These are shallow sores that are red in color and may be covered with a white coat of skin over them. They are usually found present on the base of the gums or over the mucous membranes within the mouth.

Canker sores are called as aphtous ulcer, aphthous stomatitis as well as Sutton’s Disease (in case of recurring or multiple ulcers).

These are common lesions that are not contagious in nature. Canker sores are about 1 cm in size and appear round or oval. The simple canker sores are commonly observed in adolescents and teenagers. These lesions may appear about 3 to 4 times in a year. Most of the cases do not require any kind of treatment for the sores.
