A toothbrush having an outer housing with three orifices, a neck portion, and a head portion. Three gears, each engaged with a respective landing in the head portion, include a portion that extends through a respective orifice in the housing aligned with the landings. A rotatable component engages the portion of each gear extending through an orifice. A shaft in the neck portion engages a motor or other type of actuator. In use, rotation of the shaft causes rotation of the first gear and associated rotatable component, which causes rotation of the second gear and rotateable component in an opposing direction, which in turn causes rotation of the third gear and rotatable component in the first direction.
