What Are Canker Sores?

Canker sores, also known as aphthous ulcers, are small, shallow lesions that develop on the soft tissues inside your mouth, such as the cheeks, gums, or tongue. They are usually round or oval with a white or yellowish center and a red border. Unlike cold sores, canker sores do not occur on the lips and are not caused by the herpes virus.
