Abstract

A detachable head for use with an electric toothbrush is provided. The electric toothbrush has a handle with a motor disposed therein that is operatively connected to a shaft. The detachable head has an elongate body with a longitudinal axis and a first end and a second end opposite said first end. The first end may be detachably coupled to the electric toothbrush. The detachable head has a first bristle holder with a first plurality of bristle tufts disposed thereon. The first bristle holder is located at the second end of the elongate body and can oscillate about an axis substantially perpendicular to the longitudinal axis. The detachable head also has a a second bristle holder disposed between the first bristle holder and the first end. The second bristle holder has a top surface and a second plurality of bristle tufts that form an acute angle with the top surface of the second bristle holder.
