Abstract
A toothbrush incorporates a directional inertia switching arrangement in its handle and has an electrical pressure switch that responds to bending of the brush. When the brush is used correctly to brush teeth up and down and sufficient pressure is simultaneously applied to operate the switch, LED's are caused to be switched ON and OFF. This switching ON and OFF serves to visually indicate and especially to train a young person to brush his teeth correctly.
