Treatment involves removing the infected pulp (nerve) from the root canal and replacing it with a filling. Depending on the tooth type there may be 1-5 root canals. Treatment normally takes two or more appointments. It can take longer if the tooth is very infected or if it has complicated roots. After the pulp is removed, a medication is put in the root canal space. At a later appointment, the filling is placed inside the root canal.
A dentist can carry out your root canal treatment, but if it seems difficult, you may be referred to a root canal specialist called an Endodontist.
