What should you tell a patient if you need to make an access opening through their crown for RCT?

• A. Explain that while we make every effort to preserve their existing crown, there is a chance that it may be damaged during access and a new crown would be required.
• B. We will definitely need to replace the crown.
• C. The crown will be unaffected.
• D. Access through the crown does not affect the crown at all.

Answer: (A)

When planning an access through an existing crown for root canal treatment, the patient needs honest information about potential impact on the crown and future work required to restore the tooth.

The best approach is to explain that every effort will be made to preserve the crown, but there is a chance it could be damaged during access. If the crown is damaged or its seal is compromised, a new crown may be needed after the endodontic procedure. This communicates both the intent to protect what can be preserved and the realistic possibility of requiring a replacement crown later.

Providing this balanced information helps the patient understand the procedure, the uncertainties, and the potential need for an additional restoration, which is essential for informed consent. Statements claiming the crown will definitely need replacement or that the crown will be unaffected are not reliable because the outcome depends on the crown’s material, how the access is performed, and how the tooth and restoration respond to treatment.
