Abstract

A flexible rope-like root canal prosthesis and method of use are provided for repair of a damaged tooth. The flexible rope-like root canal prosthesis is contacted with a stiffening agent to form a composite that is moldable to conform the interior of the root canal. The stiffened rope-like root canal prosthesis is bonded into the root canal and serves as a foundation for restoring the pulp cavity core and allowing for additional prosthesis to be applied to the tooth.
