Abstract: An electrically powered device for cleaning the dorsal surface of the tongue, including a handle having a longitudinal axis, and an elongate member extending from the handle and terminating in a cleaning head adapted to reciprocate in a predetermined direction. An electric motor is provided within the handle adapted to operate at a predetermined frequency and thereby reciprocate the elongate member. The cleaning head includes agitation members and one or more cleaning members, such as elongate blades or banks of bristles. The agitation are arranged substantially perpendicular to the predetermined direction of reciprocation, while the cleaning members extend across the width of the cleaning head. The elongate member has a predetermined configuration that is tuned to resonate when reciprocated at a predetermined frequency, preferably within the sonic range, i.e. between about 1,000 and about 20,000 cycles per minute, thereby inducing a resonance action in the cleaning head.

Abstract: An electric device which removes supragingival and subgingival plaque and undesirable debris from the interproximal surfaces between teeth is described. This device utilizes a combination of sonic energy and dental floss which is secured between two tines, the tines being part of a flexible fork which is removable from a powered handle which contains batteries and an electric motor. The electric motor, which is coupled to an eccentrically mounted disc on an output shaft, revolves at sonic frequencies which in turn generates sonic energy that is transmitted to the flexible fork which holds the floss. The sonic energy is synchronized and in tune with the natural resonance frequencies of the fork thereby stimulating the resonance action of oscillating vertical and/or elliptical movement of the fork which in turn imparts cleaning energy to and enhances the cleaning properties of the floss.
