Assuming it's a canker sore (these are usually IN the mouth and can be caused by an irritant (braces, broken/ jagged tooth, acidic foods, maybe a weakened immune system) and not a cold sore (usually on the lip/ outside the mouth, and caused by a virus-- which makes them contagious so don't be kissing on anyone!).... I'd suggest avoiding acidic foods-- oranges, tomatoes etc. Or anything else that seems to irritate it. Spicy foods, alcohol, mouthwash. Canker sores usually clear up within a few days.
