Abstract (en)
[origin: EP0281017A1] While brushing the teeth with known toothbrushes, whether manually or mechanically operated, the user can involuntarily apply too much pressure, which may cause damage with far-reaching consequences to the gums, teeth and dental fixing devices. Such damage may be avoided by using a toothbrush which enables the user to achieve optimum pressure for brushing the teeth by simple means, and without using additional electrical or electronic aid. The head (3) of the toothbrush is so disposed on the shaft (1) of the toothbrush, that it flexes when a certain level of pressure is reached, enabling optimum pressure to be maintained while the teeth are brushed. An acoustic and/or tangible sign may be given when optimum pressure on the shaft (1) of the toothbrush is reached, or the shaft (1) may be formed at certain points like a leaf spring, in such a way that the flexible design of the toothbrush head ensures that an optimum or maximum pressure while brushing the teeth is not exceeded.
