Hello sir.
We’re sorry to hear about your past experience with dental treatment. Your CBCT scan indicates a significantly large periapical abscess. While a re-root canal treatment (Re-RCT) can be attempted, it is important to understand that the prognosis is uncertain and long-term success cannot be guaranteed. In some cases, the treatment may not remain effective for even a year.
For a more predictable and durable outcome, the recommended long-term solution would be extraction of the affected tooth followed by replacement with an appropriate prosthesis.
Next Steps
Immediate dental consultation.
