Successively-delivered liquid pulses are led into an elongated hollowed handle of a size and shape to be grasped by the human hand. A nozzle, mounted to the handle, delivers those pulses against the teeth and gums of the user. Also mounted to the handle is a toothbrush for scrubbing the teeth and massaging the gums. Included within the handle are elements that cooperate to drive the toothbrush relative thereto.
