A root canal procedure is necessary when the soft tissue inside the tooth becomes infected or inflamed. This can happen due to deep decay, a crack or chip on the tooth, trauma, or occasionally from repeated dental procedures on the tooth.
Most teeth that have a root canal will require a crown to protect the structure of the tooth. Your regular dentist and endodontist will discuss with you the type of restoration that is best for you.
In the vast majority of cases, a root canal will heal properly and you will have no further issues with that tooth. Occasionally, however, the root canal may not heal properly, or a new condition, such as a cracked tooth or new decay, could impact the treated tooth. In these cases, a retreatment of the tooth may be necessary.
Also called a root-end resection, an apicoectomy may be needed when the bony area around the end of the tooth remains infected or inflamed following a root canal procedure.
