ABSTRACT:
A vibrating toothbrush which includes a brushhead (18) mounted for vibrating movement, a reservoir (30) for containing dentifrice which is located in the handle (14) of the toothbrush, and fluid connecting means (32) connecting the reservoir (30) to the brushhead (18). The brushhead (18) includes either hollow bristles (80) or nozzles (87) in the brushhead (18) to permit egress of the dentifrice from the brushhead (18) in the area of the bristles. The brushhead (18) is driven so as to provide a scrubbing action for the teeth and to provide acoustical energy for acoustical cleansing as well. The action of the brushhead (18) and the load thereon will result in dentifrice being released out of the brushhead (18) or bristles (80) as needed, supporting cavitation and streaming for the acoustical energy, as well as providing the cleansing/therapeutic effect of the dentifrice.
