Root Canal Retreatment

When you are referred to us, some of you would have already had Root Canal Treatment done. If that treatment has not been successful it may be due to leakage of the root filling, decay around the existing filling of the tooth, inadequate cleaning of the root canals or a missed canal.

Root Canal Retreatment aims to remove the cause of the failure and resolving that issue which usually involves removing the existing restoration and root filling. Once the cause of the failure is resolved then the root canal retreatment is done. Root canal retreatments are usually more time consuming and therefore, more expensive.

The structure of dentine (the bulk of any tooth) becomes weaker over time in root canal treated teeth due to changes in the collagen structure of these teeth. They may require added protection in the form of a crown which is done by your General Dentist. However, a 6-12 months observation period is suggested before that is done, to check whether the root canal treatment has been successful.

This treatment can be done over 1-2 appointments. The Endodontist will discuss this, likelihood of a successful treatment and the cost with you during your consultation appointment.
