Post & Core:

Post: The post is a metal or fiber rod inserted into the root canal of a tooth that has had a root canal treatment. It helps to anchor the core material and provide additional support to the tooth structure.
Core: The core is a filling material (usually made of composite resin or metal) that builds up the structure of the tooth. It provides a base for the crown that will be placed on top. If a significant part of the tooth is missing, the core helps to rebuild it so that it can support a crown.
Purpose: The post and core technique is typically used in teeth that have lost a lot of structure due to decay or fractures, providing stability before placing a crown.

These procedures help restore dental health and aesthetics while ensuring durability and support for damaged or missing teeth.
