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. The flexible fork may be removed from the handle and replaced with other dental cleaning tools such as a brush, a pick, and/or a tray attachment.
