ABSTRACT:
A toothbrush is equipped with electronic means for measuring the time interval between a visit to the dentist and the time when the next visit is to take place. The toothbrush remains "dormant" during that time interval. At the end of the interval, electronic means are activated to provide a visual and/or audible alerting signal to the user of the toothbrush. The signal is delivered during actual use of the brush. Preferably, it is repeated, at relatively short intervals, during subsequent uses of the brush.
