A mouth ulcer is a painful round or oval shallow lesion in the mouth, often on the inside of cheek but can occur on the gums, palate or lips. They are not infectious so cannot be passed on from sharing a drink or kissing someone. Whilst they are very common and generally self-limiting, it is often not known exactly how one has been caused.
