Post and Core treatment
a Post and Core is a procedure that is required in order
to rebuild and strengthen a tooth that previously had root
canal treatment. It adds the proper support necessary to
restore a tooth with a 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
