Root canal retreatment

Trust an endodontic specialist for lasting results

As with any dental or medical procedure, it’s possible your tooth won’t heal as expected or that new problems will arise in the future.

Trusting a specialist endodontist minimises the risk of failed procedures. We can also help if you have a previous root canal treatment that is causing problems.

Possible reasons for retreatment

Not every tooth anatomy follows the textbook and a root canal treatment is a delicate and specialist procedure. If a root canal gives trouble after treatment it could be because of any of the following:

Over time, other problems can arise in a tooth that was successfully treated. These include:

What happens during retreatment

Retreatment is very similar to the initial treatment and is done under anaesthetic (and sedation if requested). The endodontist will reopen your tooth and remove the filling materials that were put in the root canals during the first procedure.

The endodontist then carefully examines the tooth, looking for additional canals or new infection. Any infection is removed, the canals are cleaned and shaped, and new filling materials are placed. The endodontist will then reseal the opening with a temporary filling. You will then return to your dentist for the tooth to be restored with a permanent filling or a new crown.
