The invention is directed to a method and a device for cleaning teeth wherein a variety of cleaning tools are coupled to a common handle section for the individual cleaning of teeth. The slide member is movably mounted on the handle and includes two diverging arms. 06, a plurality of filaments being arranged in series over the thickness of the unitary body. Thereby, information used for remote operation can be transmitted between the two units over a logical path composed of the connections A and B. The predetermined data includes at least one SYNC code in a predetermined recording unit, and the number of \u201c1\u201ds included in a predetermined number of a series of channel bits at an arbitrary position in the SYNC code is not more than a half the predetermined number.
