|Placing a Post and
Core is a procedure that is required in order to rebuild and
strengthen a tooth that had root canal treatment. It adds the proper support
necessary to restore a tooth with a cap or crown.
The post itself, is a metallic or reinforced fiber structure that is placed within the root of a tooth that has had a root canal (endodontic proceedure). When a root canal is performed, the nerve is removed and the space it occupied is filled with a special filling material.
In placing a post, we remove some of this root canal filling material creating a space. The space that is created is used to anchor the post within the root of the tooth.
The type of post that is chosen, will depend upon a number of factors. Most posts used today are prefabricated. The appropriate size is selected depending on the tooth.
A core is built from filling material around the part of the post that sticks out of the root after the post is cemented into the root. The core is shaped so that it will anchor and retain a crown.
Although posts are
usually recommended when there is minimal support for a crown, they are
not always necessary. The use of a post is determined on an individual
basis based upon support and structural strength required.
