Dental abscesses can become serious problems and poses a risk, if not treated quickly. As the infection spreads, the puss can escape from the bone into open spaces between muscles and connecting tissues. Spreading infection can enter spaces and potentially become life threatening.
The cause of the infection should be treated along with the assistance of appropriate antibiotic therapy. It is important to monitor the patient for fever, that could indicate that the infection has spread systemically and treatment should be sought quickly. Also, if swelling affects breathing or the ability to swallow, you should go immediately to the emergency room.
