Abstract

The invention relates to a method and device for cleaning teeth, whereby different cleaning implements for the personalized cleaning of teeth are coupled to a common operating part. The invention particularly relates to a handpiece of an electric tooth cleaning device comprising a coupling part for coupling different cleaning implements thereto, and to the cleaning implements themselves. According to the invention, the handpiece detects a coding provided on the respectively coupled cleaning implement. Different functions of the tooth cleaning device are controlled according to the respectively detected coding.
