Canker Sores

Definition of Canker Sores:

Small, painful ulcers that occur on the inside of the cheek, lip or underside of the tongue.  They usually clear up by themselves within 3-10 days but often recur, sometimes in the form of multiple sores.  They have many causes, including mouth injury (for example, from brushing or biting the cheek), poor nutrition, stress, hormonal changes, hot food, or an assortment of viruses.

Also: Aphthous Stomatitis, Aphthous Ulcers, Mouth Ulcers
