Abstract
The tooth brush has two cylindrical brushes (1) which rotate in opposite directions. When applied to the teeth one cleans the upper teeth and the other the lower teeth, moving from the gums towards the extremeties of the teeth. The brushes are partly covered by a cap (2) which protects the cheeks and lips when the brush is in use. The cap is extended by a handle (3) which contains the spindles of the brushes. These are connected to a mechanism which rotates the brushes either by hand and by an electric motor.
