When is a Root Canal Therapy needed?
A root canal treatment is needed when a tooth's nerve and associated blood vessels are irreversibly damaged either by trauma to the tooth or because of  deep cavity. This results in infection that may lead to an abscess at the base of the tooth.

How is a Root Canal Done?
Root canal treatment consists of several steps that takes place during several visits to dentist :

  • First, an opening is made through the tooth into the pulp chamber after giving local anesthesia if needed.Root canal treatment
  • Then the diseased pulp is removed. After the diseased pulp is removed, the pulp chamber and root canals are cleaned, enlarged and shaped in preparation for being filled with files.
  • If more than one visit is needed, a temporary filling is placed in the crown opening to protect the tooth between dental visits.
  • The temporary filling is removed and the pulp chamber and root canal permanently filled. A tapered, rubbery material called gutta-percha is inserted into each of the canals and is often sealed into place with cement.
  • In the final step, a crown is usually placed over the tooth to restore its natural shape and appearance. If the tooth is very broken down, a post may be required to build it up prior to placing a crown.
