As shown in the diagram to the right, a tooth abscess is a collection of infected material or pus. An abscess can occur when the pulp, the soft tissue inside the root canal, becomes inflamed or infected and goes untreated.
Endodontists specialize in treating the insides of teeth. Therefore an abscess is the type of condition where endodontic treatment can be helpful.
How does endodontic treatment save the tooth?
The endodontist removes the inflamed or infected pulp, carefully cleans and shapes the inside of the canal, a channel inside the root, then fills and seals the space. Afterwards, you will return to your dentist, who will place a crown or other restoration on the tooth to protect and restore it to full function. After restoration, the tooth continues to function like any other tooth.
