To provide a prosthesis like an artificial tooth capable of forming the bridge directly and having abrasion resistance and aesthetic equivalent to or more than those of a conventional artificial tooth in a short time and without cutting proximal teeth, said prosthesis is made of a resin material and comprises one tooth or teeth connected two to four teeth, which are approximating to the teeth at the oral cavity side from a mucous of a dental cervix part, and recessed parts are formed at proximal surfaces of its both sides, and further, a part where some at the labial surface side is deleted in the thickness almost corresponding to the thickness of an enamel in a natural tooth and a part where some at the occlusal surface side is deleted in the thickness almost corresponding to the thickness of an enamel in a natural tooth, may be formed.
