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.
Causes of mouth ulcers. In most cases, mouth ulcers are not caused by an infection. This means they cannot be passed from person to person. For example, in most cases it is not possible to get a mouth ulcer from kissing someone who has a mouth ulcer, or by sharing drinking glasses or cutlery with them.
