Abstract

An oral care device is disclosed. The oral care device includes a housing being at least partly formed of an electrically isolating material; a capacitor having a first electrode and a second electrode, the first and second electrodes being electrically isolated by the electrically isolating material of the housing such that they are not exposed to an outside environment of the oral care device; and a processor unit being electrically connected to the first and second electrodes. The processor unit is arranged such that during operation of the oral care device it determines a capacitance (x) of the capacitor in order to determine whether the oral care device is within a user's oral cavity or not.
