Post and core

A post and core (colloquially known as a "post" or "dental post") is a type of dental restoration used either to stabilize a weakened tooth or provide an anchor for a crown. Utilized when inadequate tooth structure remains to support a traditional restoration, it consists of the insertion of a small metal rod (known as a "post") into the root space of an affected tooth, leaving several millimeters protruding. The protrusion is then used to support a large filling, or anchor a crown.
