Q: What causes mouth ulcers?
A: Mouth ulcers, or sores within the mouth, are usually caused by either accidental damage such as biting or scratches, or by aphthous stomatitis in situations whereby more than one sore is present. They can also appear as a result of a viral or bacterial infection.
Q: I have heard that having a mouth ulcer can be a sign of mouth cancer. Is this true?
A: A mouth ulcer can be a sign of the presence of an underlying disease or medical condition. In some cases this is true of mouth cancer. Any mouth ulcer that has no known cause for its appearance or has not disappeared within three weeks should be checked by your dentist.
