A detachable restoration tooth has a bottom, an outer surface, and a top. The bottom is provided with a cavity to accommodate an outer crown. The restoration tooth further has two connection portions, each extending from a boundary edge of the top and the outer surface. The restoration tooth is removably mounted on the abutment seat of a restored tooth such that the outer crown is fitted over an inner crown of the abutment seat, and that the connection portions are attached to two healthy teeth adjoining the restored tooth.
