What is the recommended course of action for a broken coronal portion of a canine?

The recommended course of action for a broken coronal portion of a canine often involves conservative endodontics and preparing for a post and core. This approach aims to save the tooth while restoring its function and appearance. When a portion of the tooth structure is fractured, particularly in the coronal area, it's essential to assess the vitality of the pulp. If the pulp is still healthy, conservative endodontic treatment can address any potential damage or threats to the pulp tissue without removing the tooth.

Once the root canal is appropriately treated, a post and core can be placed to provide support for a crown, particularly when there’s insufficient structure left to retain the crown effectively. This method not only preserves the natural tooth but also enhances its longevity compared to other options that might lead to tooth loss.

Leaving the tooth untreated poses risks for further decay or infection, which can result in more significant oral health problems. Immediate crowning without proper evaluation might not adequately address underlying issues, and extraction would be a last resort, recommended only if the tooth cannot be saved. Hence, the choice of conservative endodontics, followed by the preparation of a post and core, is a comprehensive and effective strategy for managing a broken coronal portion of a canine.
