What symptoms are worrying?
Worrying signs are things like an ulcer that does not heal, bleeding from the mouth, a loose tooth with associated bleeding or a socket that does not heal after a tooth is removed.
Who should you see?
Often the dentist is a great starting point for teeth issues. After this an ENT surgeon may need to see you to take a biopsy of the area in the mouth which looks unusual. This could sometimes be done at the time of the initial consultation but it may need to be done at a later time under a general anaesthetic.
