Endodontic retreatment may be necessary if you experience tooth pain, swelling, or if your dentist detects an abscess in a tooth that has already had a root canal. This specialized procedure uses advanced technology, including a dental microscope, to treat reinfection or unresolved issues from the original treatment.
While root canal therapy is successful in most cases, retreatment may be required due to missed canals, recontamination, persistent symptoms, or complex root anatomy. Retreatment provides a second opportunity to preserve your natural tooth and restore your oral health.
Why Endodontic Retreatment Matters
Persistent Pain
If you continue to experience pain after treatment, it may be a sign that retreatment is necessary.
Reinfection Risks
A new infection can occur in the same tooth if bacteria persist, warranting further evaluation.
Complex Root Anatomy
Some roots may have unusual shapes that can lead to difficulties in cleaning and sealing.
Advanced Techniques
With modern technology, we can effectively treat and preserve more teeth than ever before.
General FAQs
During your consultation, the endodontist uses advanced diagnostics such as 3D CBCT imaging to carefully evaluate your tooth. They will explain your condition, treatment options, and what to expect. In some cases, treatment can begin the same day; otherwise, it will be scheduled at your convenience.
Once you are fully numb and comfortable, the endodontist creates a small opening in the tooth using a specialized microscope. The previous filling material is removed, the canals are thoroughly cleaned and disinfected, and then they are refilled to promote healing and prevent reinfection.
After the procedure, it’s important to visit your general dentist within 30 days to place a permanent filling or crown. This final restoration helps protect the tooth from fractures and ensures long-term success.
