ABSTRACT:
This mechanical toothbrush produces a micro-stroke `shimmy` motion to a narrow-row soft bristle brush member. The handle part acts as a housing that holds the toothbrush stem and has two internal chambers; one of which holds a spring, the other inducts water into the hollow tubular stem of the toothbrush wherein said water will pass through to and wet the bristle brush member. The housing at the toothbrush stem end is contoured to prevent rotational motion of the toothbrush stem. The other end of the housing has a detatchable coupling to connect with a pulsed water driving source.
