PostCore Procedure:

A post is a tiny pillar made of metal or fiber that is placed in the canals of the tooth for.After the root canals are sealed with the filling material, some of the filling is removed to make room for the post. The post is then cemented in the canal with a portion of the post projecting out above the gums.

A large filling is built up around this post, using this post as additional support. This large filling is called core; such large fillings or core, can support the crowns above them only with the help of their posts which are firmly anchored in the roots for strength and support.

Crowns supported by posts and core are called ‘post core crowns’ and can last from 5 – 10 years with proper care by regularly brushing and flossing the teeth.Your dentist will decide which type is best for you based on the extent of your tooth damage or decay. A post and core procedure allows you to retain your tooth eliminating the need for an extraction and dental replacement which may be costly.
