Canker sore Elimination
A canker sore is an oral ulcer that appears alone or in clusters inside the mouth and is very painful. It is caused by a break in the mucous membrane.
They are small, red with yellowish borders. You might get them on the inside of your lips, the insides of your cheeks, the base of your gums or under your tongue.
If your canker sores are large, last longer than 2 weeks, you can't eat or drink, or if you have a fever or feel sick you should make an appointment to see our dentist for an immediate check up.
