Call your dentist as soon as possible.
Abscesses are a serious condition that can damage tissue and surrounding teeth.
An infection can sometimes spread to other parts of the body if left untreated. To ease the pain and if you feel a bump or blister, try rinsing your mouth with a mild salt water solution (1/2 teaspoon of table salt in 8 ounces of water) several times a day.
