<p>A power toothbrush brushhead includes a neck portion which is attachable to a drive member of the power toothbrush which operates in a sweeping, i.e. partially rotating, manner. The brushhead includes a neck portion and a bristle base member at a distal end of the neck portion. The bristle base member includes a central portion and two paddle members on opposing sides of the central portion. The central portion and paddle members are supported at one end thereof in cantilever fashion from the distal end of the neck portion, with the other ends thereof being free to move. The action of the drive member moves the central portion in a sweeping, back-and- forth, motion, which results in an in-and-out movement of the two paddle members.</p> |
