The aim of root canal treatment(also called endodontic treatment), is to save a tooth that has been badly damaged due to decay, disease or injury. Root canal treatment is preferred to extraction in some cases because natural teeth function better than artificial teeth. Problems with biting, chewing and oral health are associated with losing a tooth.
Root canal treatment usually require 2-3 appointments to complete. The process involves removing the nerve, bacteria, and decay and the resulting space is then filled with a dental material to prevent bacteria from re-entering the space.
To reduce the risk of fracture and restore the function of the tooth which has been root canal treated, dental crowns might be recommended.
