The invention provides a multilayered model tooth for dental training that has a crown part not easily chipped in cutting training such as crown restoration training while reconstructing a multilayered structure similar to that of a natural tooth. The multilayered model tooth for dental training includes a crown part 1 artificially produced by simulating an enamel layer 3 as a surface layer and a dentin layer 4 as an inner layer and a root part 2, and the model tooth is fabricated in a unified manner such that the enamel layer is extended from the tip of the model tooth to the root part side beyond the cervical line 6 and at least the adjacent part to the crown part and the surface of the root part in the vicinity of the adjacent part is covered with the enamel layer of the crown part. In this case, the thickness of the enamel layer covering the root part surface on the cervical line is preferably in the range of 0.02 mm to 0.3 mm.
