A tooth to be used in a dental arch model with which dental students can conduct dental works in the oral cavity and practice treatments. More specifically, a tooth composition for formation trainings such as anchor tooth formation and cavity preparation. Since conventionally used dental arch models have cutting properties different from natural teeth, dental students having completed formation trainings such as anchor tooth formation and cavity preparation by using these conventional models are frequently puzzled to have different cutting and handling properties upon dental works in the oral cavity in practice. That is, these conventional dental arch models are largely different from natural teeth in cutting properties including the slipperiness and easiness in cutting. A tooth for a dental arch model simulating the enamel texture and the dentin texture constituting a natural tooth whereby even the difference in cutting properties between the enamel texture and the dentin texture constituting a natural tooth can be reproduced by forming at least the enamel part with the use of a baked inorganic powder such as alumina.
