A post and core is a type of dental restoration
that is utilized when there is inadequate tooth structure remaining to support
a traditional restoration. Most of the cases it need after extensive tooth
structure loss due to advanced dental caries or tooth fracture. A small rod is
inserted into the root space of the tooth and protrudes from the root a couple
of millimeters after performing root
canal treatment (RCT). This rod is
referred to as a post. Commonly it is made up of metal for back teeth or fiber
post for anterior cosmetic region. The post is then used to hold a filling
material, or core, in place. Without this post there would not have been enough
tooth structure remaining to hold the filling required. Mostly the post and
core is covered with a crown.
