What action is recommended if a tooth still has radiolucency two years post-root canal treatment?

If a tooth still shows radiolucency two years after root canal treatment, it often indicates the presence of persistent infection or failure of the initial treatment. In this context, re-treatment is typically recommended, as it allows for a thorough evaluation and intervention to address any lingering infection that may not have been completely resolved during the original procedure.

Re-treating the tooth involves cleaning out the root canal system again, which may include the use of different techniques or materials to eliminate the infection and promote healing. This approach prioritizes preserving the tooth and alleviating any ongoing symptoms or risks associated with infection.

Monitoring the tooth over time might be an initial approach, but with the evidence of ongoing radiolucency, it suggests that more active treatment is necessary. Referral to a specialist can be useful in some cases, particularly for complex scenarios, but it may not be the first line of action if re-treatment is viable and the dentist is equipped to handle it. Performing a surgical extraction should be considered only if all other options fail or if the tooth is deemed non-salvageable, which is not the case here.
