Abstract

The invention is directed to an apparatus for treating the teeth and/or gums. This apparatus includes a treatment tool (1) for removing plaque in particular from the gum margin and/or for stimulating the gingival tissue. The treatment tool (1) is adapted to be set in vibration. For example, it is possible to generate the vibration by an unbalance structure (12) on a drive shaft (7) of the apparatus. The vibration results in a substantial improvement of the tooth cleaning and/or gum stimulating action.
