Abstract
The oral hygiene device, particularly a toothbrush, has in the neck part, a cavity, which is closed off from the surroundings and in which a snap dome is arranged. This snap dome produces an acoustic warning signal when a limiting bending of the neck part is exceeded as a result of a limiting pressing force with which the head part is pressed, for example, against the teeth and gums is exceeded. On the one hand, this has the effect of protecting the snap dome, usually produced from metal, from corrosion and, on the other hand, the cavity serves as a resonance chamber to amplify the warning signal.
