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.
In a few cases, a long-lasting mouth ulcer can be a sign of mouth cancer. Ulcers caused by mouth cancer usually appear on or under the tongue, although you can get them in other areas of the mouth. It's important to detect mouth cancer as early as possible.
