The only cure for an abscessed tooth is treating the infection causing the abscess, according to MedicineNet. This generally involves taking oral antibiotics or visiting the dentist, who drains infection from the affected tooth and surrounding structures in the mouth.
After the infection clears, a return trip to the dentist for an extraction or root canal is necessary to ensure the abscess does not return, notes MedicineNet. Although there is no home cure for an abscessed tooth, there are some remedies to alleviate its associated symptoms. Using over-the-counter pain medications, placing a warm wet teabag compress over the affected area, and rinsing with baking soda or saltwater solutions can help to ease the pain of an abscessed tooth.
