ENDODONTICS (POST REINFORCEMENT FOR WEAKENED TEETH)
Root canal therapy requires the removal of a significant amount of internal portion of a tooth to gain access to the root canals and to remove infected materials. If the tooth has had previous restorations (fillings), or has to support a fixed bridge, it may need internal reinforcement to ensure that the root and the crown portions of the tooth are connected together adequately. Various types of posts are used to connect the root and crown. A post is cemented in the tooth root, and a core, or replacement of the missing portion of the crown is placed on the top of the post.
The root end of the tooth will remain filled with the root canal filling. The post will be cemented with a strong epoxy-like material that bonds the post and the tooth together.
The post and core provides optimum potential for this tooth to continue to serve in your mouth for many years.
