When a tooth has died, usually as a result of decay or trauma, it can become infected and an abscess may develop. The aim of root canal treatment is to clear up the infection by thoroughly cleaning out the canal and then to seal it so that we can save the tooth. It is usually necessary to provide crowns on the teeth that have had this treatment since they become brittle and may discolour. We employ the latest nickel titanium instruments to clean the tooth effectively with minimal discomfort.
