The mouth ulcer is a small but painful lesion in the mouth, inner cheek, tongue or gums [1, 2].

Also called canker sore or aphthous ulcer, mouth ulcer is often confused with cold sores. But this one is not contagious, and usually does not need medical treatment. It can heal on its own within one to two weeks [1].

It also looks different. Cold sores are pus-filled blisters. Mouth ulcers are open lesions enclosed within a white or yellowish ring [3].

The exact cause of mouth ulcer is unknown. But in most cases, it is a result of damage or trauma to the lining inside the mouth. The reasons can be poor-fitting dentures, over-brushing, or accidental biting in the mouth. [2, 3]

Mouth ulcer usually goes away on its own after a few days or weeks. But it can make eating and talking difficult. So, you might want to get immediate relief using some home remedies for mouth ulcer.
