Claim:
A method for producing a tooth for a dental arch model comprising an enamel portion and a dentin portion, which is used for practice treatments, wherein the method comprises steps of: molding pellets including an inorganic powder and a binder to form a tooth molding having a two-layered structure of an enamel portion molding and a dentin portion molding, wherein the inorganic powder of the enamel portion molding has a primary particle diameter ranging from 0.1 μm to 1.0 μm and the inorganic powder of the dentin portion molding has a primary particle diameter ranging from greater than 1.0 μm to no more than 8.0 μm; heating the tooth molding at high treatment to degrease the binder; and sintering the degreased tooth molding at a predetermined temperature to form a sintered body of the tooth for a dental arch model comprising the enamel portion and the dentin portion.
