What is the primary purpose of a fiber post in endodontically treated teeth?

The primary purpose of a fiber post in endodontically treated teeth is to retain the core material. After a tooth undergoes endodontic treatment, it often requires additional support to rebuild the structure that may have been lost due to decay or previous restorations. The fiber post is placed within the canal of the tooth and acts as an anchor for the core buildup material that restores the tooth to its proper shape and function.

This core material is essential because it provides the necessary foundation for the final restoration, which often includes a crown. The fiber post also adds some support and load distribution to the remaining tooth structure, helping to prevent future fractures. However, its primary role is to effectively secure and retain the core material that reconstructs the tooth.

Understanding this function is crucial for successful endodontic treatment outcomes. In essence, while reinforcement and foundation roles may resonate with aspects of the post's function, retaining the core material is a critical aspect that underscores its essential role in the overall restoration process following endodontic therapy.
