What is root canal treatment?: Dr Jennifer Pindar, Dentist
Root canal treatment can happen when a nerve is exposed through tooth decay, or the nerve becomes painful. And what happens is that the inside of the tooth, has to be cleaned out, right up into the roots, and is often done by somebody who is a specialist in root canal treatment.
A lot of patients are very frightened of the word 'root canal treatment', because they imagine it's going to be very painful, and if the person who is doing the treatment makes sure that it's absolutely numb, there is no reason to be afraid of it.
