What is a Root Canal?

Root canal treatment is the removal of damaged, diseased or dead pulp in the centre of the tooth. The remaining space is cleaned, shaped, filled and sealed up.

Common Causes of Pulp Damage:

A cracked tooth
A deep cavity
An injury to a tooth

Once the pulp is infected or dead and left untreated, pus can build up at the root tip in the jawbone, forming an abscess. An abscess can destroy the bone surrounding the tooth and cause pain.

How is Root Canal Done?

There are several steps over 2-4 visits depending on the case.

Step 1

Local anaesthesia is placed to numb the involved area.

Step 2

An opening is made behind the front tooth or the biting area of the affected back tooth. To have access to the dead pulp.

Step 3

The diseased pulp is removed (pulpectomy), the pulp chamber & root canals cleaned, enlarged and shaped in preparation for being filled.

Step 4

A temporary filling is placed in the crown opening to protect the tooth between dental visits.

Step 5

The temporary filling is removed, the pulp chamber & root canal permanently filled. A material called guttapercha is inserted into each of the canals and sealed into place with cement. Sometimes a metal or plastic rod is placed in the canal for structural support.
