Abstract: An electric toothbrush having bristle driven pulsation includes a brush head having a bristle holder and bristle tufts attached to the bristle holder. The bristle tufts and corresponding bristles are disposed at a perpendicular and/or a non-perpendicular angle with respect to a mounting surface of the brush head. The electric toothbrush also includes an electric toothbrush handle removably attached to the brush head. The electric toothbrush handle includes a linear motor configured to drive the bristle holder via a gearing structure coupled to the linear motor and the bristle holder. The linear motor causes the bristle holder to rotate clockwise and counterclockwise at a rotation frequency which exceeds a rotation frequency threshold (e.g., 100 Hz, 120 Hz, etc.). The linear motor also causes the brush head to vibrate in a direction toward and away from a contact surface in synchronization with the rotation of the bristles.
