To ensure that this treatment is painless, your dentist will numb the area around the tooth

Your dentist may apply a sheet of thin rubber around the tooth, which will be attached to a metal or plastic frame outside the mouth. This is to ensure that the root canal is kept dry during the treatment

In order to see the opening of the root canal, your dentist will make a hole in the tooth. A narrow file will then be used to find the root canals and take out any dead nerves

Your dentist will then fill the roots and apply a paste, so that it will set hard.

You may need to take some mild painkillers after the treatment, as the tooth may still feel tender for one or two days
