ENDODONTIC RETREATMENT · MYSURURe-Root Canal Treatment
A previously treated tooth may sometimes remain painful or become infected again. Retreatment reopens the tooth so the canal system can be reassessed, cleaned and sealed where feasible.
01Why can a treated tooth need reassessment?
Persistent bacteria, complex anatomy, a leaking restoration, a new crack or delayed final restoration can contribute to symptoms.
- Pain or tenderness when biting
- Swelling or a gum boil
- A new radiographic finding
- Breakdown of the filling or crown
02How retreatment is planned
The existing restoration and root filling are assessed. Additional imaging or magnification may be recommended. Whether the tooth can be predictably retreated depends on restorability, anatomy and the cause of failure.
COMMON QUESTIONSClear answers before your visit.
Can every failed root canal be retreated?+
No. The tooth must be examined for cracks, remaining tooth structure and other factors before options are discussed.
Is retreatment different from the first root canal?+
It can be more complex because previous filling materials and restorations may need to be managed before the canals can be reassessed.
