Most of the time, root canal therapy is sufficient to remove infection and save your tooth from extraction. In some instances when the tooth does not heal, anapicoectomy may be necessary. This microsurgical procedure consists of folding back the gum near the tooth so that the doctor can access the underlying bone and infected area. Once the infected tissue has been removed, the very tip of the root is also removed and the end is sealed with a biocompatible material. The gum is repositioned and sutured so that healing can occur. The bone around the root will naturally heal over the next few months.
