ABSTRACT:
A device for inserting an elastomeric separation ring between adjacent teeth in a person's mouth, comprising a ring holder comprising a stem adapted to extend through and to hold a series of rings, a closed loop of strand material extending from one end of the ring holder and being adapted to receive rings thereon so that two segments of the loop pass through the opening in the ring, and two stops for the rings one stop at each end of the ring holder. In the use of the device when a series of rings is held on the ring holder, one of the rings on the stem is moved onto the loop of strand material, the loop of strand material is formed into two loops one on each side of the ring, the two loops are elongated in a direction radially of the ring so as to deform the ring into a narrower thickness, the deformed ring is inserted between adjacent teeth and thereafter the loop of strand material is pulled through the ring to remove the loop of strand material from the person's mouth, thereby allowing the elastic forces in the ring to return it toward its undeformed shape, to thus cause the teeth to be moved apart to increase the spacing therebetween.
