The microsurgery

Choosing endodontic microsurgery may save your tooth in the following situations:
  • you experience persistent symptoms but cannot diagnose the problem : microsurgery may be then useful. This happens especially when small roots fracture or are atypically shaped;
  • when calcification does not allow to access the terminus of the root : microsurgery is necessary, replaces the conventional disinfection techniques that were previously impossible to perform;
  • if an infection persists after 1 year or if retreatment is impossible, microsurgery remains still an option so as to prevent tooth extraction.

Hospitalization is not necessary. Microsurgery is comfortable under local anesthesia. Medication can also be prescribed for your well-being.

It consists in raising the gum to expose the infection. The last few millimeters of the tooth are removed from the root, as well as the bone tissue around the infected root. The opening of the root canal is enlarged and then sealed by a biocompatible material. A bone graft may be needed to enhance the healing and the regeneration of the bone. The new bone tissue will be completely formed in 1 to 3 years, depending on the volume of the initial bone defect.

New materials and use of microscope have greatly improved the success rate of such interventions. To avoid any cyst recurrence (usually when root is fractured), a radiographic examination is recommended every six months.
