Endodontic retreatment
When an old root canal treatment fails or causes discomfort, retreatment makes it possible to redo the canal and save the tooth once again.
When should a tooth be retreated?
Over time, a root canal treatment can become reinfected or turn out to have an incomplete filling. Retreatment involves reopening the tooth, removing the old material, disinfecting the canals again and then refilling them.
Performed under the microscope, it offers a second chance to keep the tooth before an extraction is considered.
Signs that a treatment needs redoing
- Persistent pain or discomfort in a tooth that has already been treated
- Swelling or a small spot on the gum
- Signs of infection visible on an X-ray
