Abstract

ABSTRACT OF THE DISCLOSURE

An electronic toothbrush has a handle accommodating a light-emitting diode or a sound-producing device as well as an electric circuit for actuating the diode or device. When a current is caused to flow through the toothbrush by grasping the brush and bringing it into contact with the teeth, light or sound is emitted to notify the user that the toothbrush is operating.
