What to do in case of failure of root canal treatment?

Mostly, the root canal treatment is renewed and the solution is reached by removing the error, if any. The old canal filling is removed, the canal of the tooth is reshaped, cleaned, sprayed and refilled. If there is no result with this procedure, a surgical intervention called ‘root tip resection’ is applied. During this process, the root of the tooth is reached; this area and its surroundings are surgically cleaned and closed. In multi-rooted teeth, the infected root is removed. If a solution cannot be reached with surgical intervention; extraction of that tooth may be considered appropriate.
