Failed Root Canal Treatment (RCT)

We can assist in cases concerning failed root treatment.


Root treatment, which is also referred to as endodontics is needed when the blood or nerve supply of the tooth, known as the pulp, is infected through decay or injury.

You may not feel any pain in the early stage of the infection.  In some cases, your tooth could darken in colour which may mean that the nerve of the tooth has died or is dying.

If the pulp has become infected, the infection may spread through the root canal system of the tooth.   This may eventually lead to an abscess.  An abscess is an inflamed area in which pus collects and can cause swelling of the tissues around the tooth.  If root canal treatment is not carried out, the infection will spread and the tooth may need to be taken out.

The purpose of root canal treatment is to clean out the entire root canal system, which is the source of the infection, and then shape and obliterate the space with a root filling.

Why can problems develop?

When your dentist is filling the root canal, it should ideally extend to approximately 1mm of the tip which would then be sealed by the root filling.  In the event that the root is not fully filled, it can lead to ongoing infection at the root and it’s surrounding bone.

To ensure that the root has been properly filled, it is therefore essential that your dentist obtains pre and post operative radiographs to check the filling material is correctly placed within the roots and if not, appropriate adjustments should be made or the tooth monitored if this might be considered impractical.
