A temporary or long-term provisional crown includes a shell having a top wall defining an occlusal surface, a buccal sidewall, a lingual sidewall, and opposite mesio-distal sidewalls, connected to the top wall and buccal and lingual sidewalls and spaced apart to define a central cavity to fit over a prepared tooth. A quantity of resin is disposed in the central cavity of the shell and is preferably shaped to conform to a prepared tooth. A partial opening is preferably arranged in one or more of the mesio-distal sidewalls to permit resin to protrude mesio-distally from the cavity to contact an adjacent tooth.
