FAQ
Common questions
When should a mouth ulcer be checked?
If it has not healed after about two weeks, or is a lump or a red or white patch that is not settling, have it assessed by a dentist or doctor.
Is a lasting ulcer an emergency?
Usually not, but it should not be ignored. Persistent mouth changes need examination to find the cause and the right next step.
What should I note before the visit?
Where it is, how long it has been there, whether it is changing, and any pain, numbness, bleeding or difficulty eating.
