The post and core procedure is a dental restoration technique used when there is insufficient tooth structure remaining to support a crown in teeth that have undergone trauma, decay, or fracture that left them structurally weak. The post and core serve as a foundation for the crown. • Before a post and core procedure, the tooth must undergo a root canal, where the infected or damaged pulp is removed. • After the root canal, a post is placed into the prepared root canal space. This post can be made of metal, carbon fiber, or ceramic. • The post provides support for the core material, ensuring the restored tooth has sufficient stability. • The core is built around the post. It is typically made of composite resin or a dental amalgam and helps restore the bulk of the tooth. • The core provides a base for the future crown. • Once the post and core are completed, a crown (usually porcelain, metal, or a combination) is placed over the tooth to restore its function and appearance. • The crown protects the tooth from further damage and restores its shape and strength. Benefits: • Reinforces and strengthens a compromised tooth. • Provides long-term stability, preventing fractures. • Allows the tooth to function normally with a natural appearance.
