Root canal treatment (RCT)

A root canal is a treatment used to repair and save a tooth that is badly decayed or becomes infected. During a root canal procedure, the nerve and pulp are removed and the inside of the tooth is cleaned and sealed.

Root end surgery (Apicoectomy)

In this procedure, the endodontist opens the gum tissue near the tooth to see the underlying bone and to remove any inflamed or infected tissue. The very end of the root is also removed


It is a method of treatment for immature permanent teeth in which root growth and development ceased due to pulp necrosis.


It is a procedure that addresses the shortcomings involved with capping the inflamed dental pulp of an incompletely developed tooth.

The success rate of Root Canals is usually between 85-95% of all the Root Canals performed but the failure rate increases and changes from patient to patient and dentist to dentist depending on many factors.
