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 injury: biting or chewing the inside of the mouth causes ulcers as does the excessive use of a toothbrush. They can also be caused by dental treatment, a sports injury or poorly fitting dentures. Bad diet: a diet lacking in certain vitamins, folic acid or iron can trigger the development of mouth ulcers.
