Canker sores (aphthous ulcers or aphthous stomatitis) are small, painful ulcers inside the mouth. They may occur on the tongue and on the inside linings of the cheeks, lips, and throat. They usually appear white, gray, or yellow in color, with a red border.
Canker sores are among the most common types of oral lesions, affecting about 20% of people. Women get canker sores more often than men. Canker sore susceptibility may be inherited, and the condition can run in families.
Canker sores are not the same as cold sores (fever blisters), which are an infection caused by the herpes virus and are contagious. Canker sores are not contagious, and are categorized into three types:
