PROBLEM TO BE SOLVED: To provide a dental composition that is beneficial for an artificial tooth and the like in that the composition has a low adhesion to a cyanoacrylate instantaneous adhesive agent used for a support projection to prevent the artificial tooth from moving or coming off in the flask and the artificial tooth is not deteriorated by the solvent in the instantaneous adhesive agent, and to provide an artificial tooth using the dental composition. SOLUTION: The dental composition contains 40-60 pts.wt. of (A) a polyalkyl (meth)acrylate copolymer having a bridge structure in the molecular chain with at least one kind of monomer selected from (meth)acrylates having one unsaturated double bond and one kind of monomer selected from (meth)acrylates having two or more unsaturated double bonds, and 20-30 pts.wt. of at least (B) one kind of monomer selected from (meth)acrylates having one or more unsaturated double bonds.
