If a tooth is nonvital, what is fabricated and placed into the pulp for better retention of a crown?

Crown only

Filling material

Bridge

Post and core

A nonvital tooth means that the tooth is no longer living, and therefore remains in a weakened state. In order to strengthen the tooth for the placement of a crown, a post and core is necessary. A crown alone would not be able to provide enough support, and a filling material or bridge would not be able to provide the necessary retention for the crown. Therefore, a post and core is the best option for a nonvital tooth in need of a crown.
