ABSTRACT:
An ultrasonic toothbrush for daily removal of soft plaque including a handle constructed of a rigid material, a battery pack, an electronics driving module, a piezoelectric member, and a removable brush-head. The low voltage DC energy supplied by the battery pack is converted to an ultrasonic frequency DC current by the electronics driving module. The piezoelectric crystal resonates, expands and contracts volumetrically, in the tune with the frequency supplied by the electronics driving module and thereby converts the electronic energy into sound-wave energy. The sound-waves driving the dentifrices in the mouth of the user against the teeth causing mild cavitation within the dentifrices at the junction with the teeth, resulting in a loosening effect on the soft plaque on the surface of the teeth and in the periodontal pockets formed in the gums around the neck of the teeth. The loosened soft plaque is then dislodged by the bristle clusters of the toothbrush by the normal brushing movements of the user.
