Claim:
A tooth cleaning system, comprising: a toothbrush having a brush head, a pressure sensor and a transmitter, said pressure sensor being positioned on said brush head so as to measure the amount of pressure applied by a user to user's teeth, said transmitter being coupled to said pressure sensor for transmitting a signal when the pressure measured by said pressure sensor is within a predetermined range; an output device having a receiver for receiving the signal from said transmitter, said output device being configured to play back a pre-recorded multimedia recording in response to the receipt of the signal by said receiver, said transmitter being configured to cease the transmission of the signal to said receiver and to thereby cause said output device to cease the playback of said pre-recorded multimedia recording when the pressure measured by said pressure sensor is outside said predetermined range, whereby said pre-recorded multimedia recording is played back only when the measured pressure is within said predetermined range so as to motivate the user to use said toothbrush properly, and said transmitter being configured to resume the transmission of the signal to said receiver and to thereby cause said output device to resume the playback of said pre-recorded multimedia recording when the pressure measured by said pressure sensor falls within said predetermined range; and a remote database including a plurality of pre-recorded multimedia recordings, said remote database being configured to communicate with said output device so as to transmit one of said plurality of pre-recorded multimedia recordings to said output device, said pre-recorded multimedia recording played back by said output device being said one of said plurality of pre-recorded multimedia recordings.
