Abstract
A removable toothbrush head for an electric toothbrush includes a bristle carrier and an elongated neck. One end portion of the elongated neck includes an opening for connection to an electric toothbrush handle, and another end portion comprises a neck hub configured to rotatably support the bristle carrier. Also included is a driven brush shaft disposed longitudinally within the elongated neck. The brush shaft is configured to interact with the bristle carrier at a distal end portion of the brush shaft, which includes a pivot extension extending therefrom and spaced apart from the longitudinal axis of the brush shaft, as well as a bristle carrier interface positioned at least partially along the longitudinal axis of the brush shaft and configured to cause partial rotational motion of the bristle carrier when the brush shaft is driven by an electric toothbrush handle.
