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.
No one knows what causes these small, painful blisters inside your mouth. Triggers include injury, hypersensitivity, infection, hormones, stress and not getting enough of some vitamins. Also called aphthous ulcers, mouth ulcers can appear on your tongue, cheek and gums. They usually last a week or two. Mouth ulcers can be treated with numbing gels.
