The invention relates to a dental prosthesis, produced from a one-piece or two-piece prosthesis blank which is constructed from a gum-colored material and a tooth-colored material (32), in particular in each case on a plastic base. It is characterized by the tooth-colored material (32) of the blank (10) which, in the blank state, has a size larger than a human dental arch. It is in particular at least 8 cm wide. The invention is further characterized in that the gum-colored and the tooth-colored material (10 and 32) are intensively connected to each other, whether by one-piece production, by adhesive bonding or by polymerization, in particular by polymerization. Viewed along the course of the dental arch, the interface between the materials has an undulating shape and, viewed in the vestibular direction, has a radial shape.
