Retreatments deal with the correction of previous deficiencies or errors.
The goal is the same – to completely disinfect, clean and seal the canal system. The main reasons for this treatment are:
- persistent or renewed bacterial colonization of the canal
- technical deficiencies during the initial treatment
- previously unseen or insufficiently instrumented canals
Retreatments may be performed to enhance the sometimes difficult and complex demands that are required of a root canal therapy. Absolutely necessary for the success of retreatment is the use of strong magnification (e.g. surgical microscopes) and a specialist who has many years of experience.
