ABSTRACT:
An electronic toothbrush has a piezo-electric element with electrodes on both sides mounted in a handle of a toothbrush. Electrons generated due to vibration of a handle effectively remove dental plaque having a tendency to be charged with positive electricity. A diode is electricity connected to electrodes on both sides of the piezo-electric element to rectify the electric current to neutralize positive and negative charges generated on both electrodes when positive charges are generated on an electrode in close vicinity to a brushing portion of a handle.
