ABSTRACT:
A tooth cleaning device for optimal tooth cleaning comprises, on a U-shaped carrier (109), tufts of bristles (180), which are placed against the tooth using pressure bubbles (149) under equal cleaning pressure on both sides. With this arrangement the tufts of bristles (180) are fitted to individually self-positioning rocker arms (174, 178'), in order to also engage in the spaces between the teeth, which are difficult to access. With the aid of a further pressure bubble arrangement (147) using phase-shifted pulsating pressurization, with reference to the pressure-generating bubbles (149), a wiping movement of the tufts of bristles (180) with cleaning pressure is generated in the direction from the gum towards the crown of the tooth, in counter-direction without bearing pressure on the tooth.
