A handle has distal and proximal ends and a drive mechanism. Operational components on the handle include ON and OFF controls and a vibrating coupler to create sonic vibrations. A coupling head has a distal and a proximal ends. The proximal end is formed with a coupling recess. A replaceable holder has a central base and two outwardly extending fingers. The fingers have free ends with a piece of floss secured there between. The central base has a shape for coupling to and uncoupling from the coupling head. The length of the floss between the fingers is from 5 to 10 percent greater than the distance between the fingers. A compressible stop is on the base of the holder between the fingers. The remainder of the fingers are devoid of a compressible stop.
