Abstract
An electric toothbrush with a casing has a sensor means and a signal emitting means. The toothbrush can be coupled to a charging station. The sensor means detects the coupling and/or uncoupling of the charging station and the casing and activates the signal emitting means, which then emits signals that are perceptible to the operator.
