Root Canal Therapy
When a tooth has undergone extensive damage either from a heavy fall or a large decayed lesion, the pulp (blood supply or "nerve") of the tooth slowly retreats and dies, leading to infection and in most cases, pain. If left untreated, the infection will spread to surrounding tissues and at worst can reach the brain tissue. In any case where there is facial swelling that reaches the eye, the patient needs to go to the hospital immediately for antibiotic treatment.
Root canal treatment is the process of removing infected or dead pulp from a tooth and replacing it with dental materials over three appointments. This enables the tooth to be retained. This saves your tooth, however, it does leave it in a more brittle condition because the blood supply is no longer there. A root canalled tooth can be compared to a dead tree; it is more brittle than when it was alive, and therefore needs reinforcement; in this case a crown for strength.
