Redoing Root Canal Treatment

What are the symptoms of tooth reinfection?

Sometimes there is no pain but there may be a swelling or a lump on the gum next to the tooth discharging pus.


Are there any alternatives to root canal retreatment?

There is the wait and see approach but usually the only real alternative to undergoing root canal retreatment is to have the tooth extracted.

If teeth are removed and not replaced, there is a chance that the neighbouring and opposing teeth can tilt, over erupt or drift and cause bite disturbances.


Does root canal treatment work every time?

No, root canal retreatment has a success rate of around 75% and it can on occasions fail. If a well carried out root canal retreatment fails, the tooth is either extracted or apicectomy microsurgery is carried out to save the tooth.

How does redoing root canal treatment work?

Patients usually visit a specialist endodontist for root canal retreatment as infection in such cases are usually more severe and difficult to manage. Endodontists have had an extra four years of specialist training in root canal treatment and use the most innovative techniques and materials, including dental microscopes, rotary endodontics and electronic apex locators, to ensure the best treatment outcomes are achieved.

Sometimes the reason that the root canal treatment failed in first place maybe due to the tooth having unusual or complex anatomy. In such cases, the endodontist may recommend having a 3D X-ray CBCT scan of the tooth carried out before redoing the root canal treatment. We have the CBCT machine on-site, should a 3D scan be necessary for your tooth.
