Embodiments relate to a dental prosthesis molding block for producing a dental prosthesis part, to a corresponding method for producing a dental prosthesis part, and to such a dental prosthesis part. The dental prosthesis molding block has a dentin zone, which is embedded into an enamel region, a boundary surface thus being formed. The boundary surface of the dentin zone has a first dentin surface, which is directed toward the labial surface of a first potential dental prosthesis part, and a second boundary surface for forming a second dentin surface, which is directed toward the labial surface of a second potential dental prosthesis part. The first and second dentin surfaces preferably have respective convex shapes, wherein the sizes and/or shapes of the two dentin surfaces preferably differ from each other.
