Abstract
A device for monitoring the process of toothbrushing has a handle that is electrically connected to signalling means. The handle has a neck and the neck is designed to consecutively receive various heads of toothbrushes. Removable and replaceable heads, with numerous bristles thereon, can be consecutively mounted on said handle. There are sensing means on the neck to continuously measure a bending moment of the area to which said sensing means is attached. As pressure is exerted on bristles of the head, that pressure is transmitted to said neck and the signalling means can be activated. The device is useful in teaching appropriate methods of brushing, thereby reducing or eliminating abrasion of the teeth. In addition to pressure, the device is able to monitor frequency, duration and direction of brushing.
