1. A multi-motion toothbrush comprising:
- an elongated body having a first end and a second head end opposite from said first end, said body defining an interior hollow region accessible from said first end;
a first moveable bristle carrier secured to said body and disposed proximate said second end of said body;
a second moveable bristle carrier secured to said body and disposed between said first bristle carrier and said first end of said body;
an electrically powered motor disposed in said elongated body, said motor providing a rotating powered output;
a positionable switch for selectively activating said motor, said switch accessible along said elongated body;
a drive mechanism disposed in said elongated body and engaging said output of said motor to said first bristle carrier and said second bristle carrier; and
a battery disposed in said hollow region of said elongated body for providing electrical power to said motor upon positioning of said switch;
wherein said first bristle carrier undergoes one dimensional periodic linear movement and said second bristle carrier undergoes two or three dimensional periodic primarily linear movement upon activating said motor by use of said switch.
