A root canal can save many important teeth that may otherwise need to be pulled. Tooth fracture, deep decay, a deep filling or crown may cause the nerve inside the tooth to deteriorate. This can cause pain or infection. The painful nerve, or in some cases the dead nerve, is carefully cleaned away while the tooth is totally numb. The nerve is in a thin canal from about the height of the gum line to the root tip. The last part of root canal treatment involves filling this canal to seal out any infection. You can save your tooth and avoid the trauma of extraction.
