Summary. 1  A mouth ulcer is the loss or erosion of the delicate lining tissue of the mouth (mucus membrane). 2  The most common cause is mechanical injury, such as accidentally biting your cheek. 3  In most cases, mouth ulcers are harmless and resolve by themselves in a few days without the need for medical treatment.
Mouth ulcers often cause pain and discomfort, and may alter the person's choice of food while healing occurs (e.g. avoiding acidic or spicy foods and beverages). They may form individually or multiple ulcers may appear at the same time (a crop of ulcers). Once formed, the ulcer may be maintained by inflammation and/or secondary infection. Rarely, a mouth ulcer that does not heal may be a sign of oral cancer.
