What is an abscessed tooth?

 a patient is worked on in the dental chair | St Paul MN DentistAn abscess is a type of localized infection and there are two types of dental abscess: Endodontic abscess and Periodontal abscess.

Endodontic Abscess

Inside each tooth there is some live soft tissue called the pulp.  The pulp is the organ that forms the tooth and the remnants are trapped inside.  If the pulp is damaged by trauma or bacterial decay that reaches the pulp the pupal cells die and bacteria invade resulting in dental abscess.  Some of the symptoms of endodontic abscess are: pain localized to one tooth or to a general area, pain with chewing or tapping on a tooth, swelling above the tooth, or facial swelling.  The treatment for for an endodontic abscess is either root canal therapy,  which allows you to keep the tooth, or extraction.

Periodontal Abscess

There is a cuff of gum tissue around each tooth.  A periodontal abscess results when a piece of food (eg. popcorn hull) gets stuck between the tooth and the gum.  Inflammation  and infection of the gum tissue are a response to this foreign object.  The symptoms of periodontal abscess are: localized pain around the gum line, swelling at the gum line or between teeth.  The treatment for periodontal abscess involves the removal of the food from the gum line under local anesthetic.

If you are experiencing any pain or believe you have a dental emergency, please do not hesitate to contact us. We will be sure to have you seen as soon as possible for an exam with Dr. O'Neill.
