When a root canal treatment is performed, the canals are sealed to prevent bacteria from entering the tooth. However, if bacteria reinvade the tooth and reach the tip of the root, an infection or abscess can form in the surrounding bone. Sometimes this condition is painless and only detected on an x-ray, while other times it manifests as painful swelling.
Common reasons for infection after a root canal include:
-
Bacteria re-entering due to a compromised crown or filling.
-
Deterioration of a temporary restoration leading to decay.
-
Narrow or curved root canals that were not fully cleaned during the initial treatment.
-
Inadequate sealing of the root canals.
-
Cracks in the tooth that allow bacterial entry.
Once a bacterial infection is identified, it is essential to remove the bacteria, clean the canals, and reseal the tooth. This is known as a root canal retreatment. The procedure involves:
-
Creating a small access hole in the tooth.
-
Removing any obstructive materials such as crowns, posts, or core materials.
-
Cleaning and reshaping the root canals, removing bacteria and old filling material.
-
Identifying previously overlooked canals or cracks.
-
Sealing the canals and placing a temporary filling or crown.
A careful examination of the tooth, surrounding gums, and bone is necessary to determine the best approach. All treatment options, risks, benefits, and alternatives are reviewed before proceeding with retreatment.
