Mouth ulcers are a common condition that cause small, painful sores to appear inside the mouth. They can show up on the gums, tongue, cheeks, or soft palate. While they usually heal on their own within a week or two, they can be bothersome, especially when eating or speaking.
These ulcers usually look like round or oval sores with a white or yellow centre and a red border. They can vary in size, from small to larger ones. Some people get one ulcer at a time, while others may have several at once.
