The device which is adapted to be secured between two existing teeth is suitable for supporting an artificial denture to replace an anterior tooth or a posterior tooth. The device is comprised of a backing member having two complimentary parts which are mounted for sliding movement relative to each other. Each part is provided with a laterally extending projection adapted to be located in a groove in the side of an adjacent real tooth whereby upon sliding movement of the two parts, the distance between the ends of the projections can be shortened to allow placement of the device between two existing teeth. The two parts can then be slid relative to each other to extend the projections into the grooves in two spaced apart real teeth. A threaded clamping member is then tightened to secure the two parts against relative movement with respect to each other and a facing member is secured to the backing member.
