Abstract
The present invention comprises a toothbrush supporting brushing behavior reinforcement means. A simple motion sensing means is electrically connected to a brushing logic means, which determines generalized brushing action of a user preferably a child. After the logic requirements of motion sensing are complete, the logic means directs a digital output display means to output to a small LCD screen or speaker a visual and/or audible reward to the user, preferably in the form of an enjoyable game or congratulatory message.

A toothbrush for reinforcing brushing behavior comprising:
- (a) the toothbrush supporting a motion sensing assembly, a logic means for receiving a motion sensing assembly input and outputting a display output, and a display;
- (b) the motion sensing assembly comprising a shell having a bore, closely associated electrical contacts in the bore and a metallic ball capable of rolling within the bore across the contacts;
- and
- (c) the logic means is electrically connected with the contacts such that adjacent contacts comprise an uncompleted circuit which closes on connection by the ball, whereby the logic means records such circuit completions as counts.
