Abstract (en)
A toot-brush comprising a handle (3) and a brush portion (5). The handle contains a piezo-electric generating element (4) having two electrodes (7,8). A diode (9) is situated between electrodes (7,8) for rectifying the flow of negative electrons from the brush portion (5) via the user's body to the handle (3). The flow of electrons induces a reducing process which effectively removes dental plaque.
