An oral care implement (1) comprising: an
electrode pair with an impedance formed therebetween when electrified; a frequency generator, electrically connected to the
electrode pair, for applying a
voltage with at least two different frequencies between the
electrode pair; an impedance measurement unit, electrically coupled to the
electrode pair, for measuring impedance values between the
electrode pair at least at the different frequencies; and a contact determination unit, in communication with the impedance measurement unit, wherein the contact determination unit comprises a memory for storing a function, wherein the function correlates impedance values of a defined oral area at the different frequencies, and wherein the contact determination unit comprises a processor for
processing the measured impedance values to the stored function so as to determine contact information of the
electrode pair with the defined oral area.
