It cleans the spaces between the teeth even twice better than the toothbrush.• 3D movements provide stunning cleaning effects without any effort. Pulse movements break the bacterial plate, while oscillating and rotational movements gently remove it. All you have to do is apply the head of the sonic-rotation toothbrush to the tooth surface, wait 2 seconds – without making any extra moves! In the case of sonic toothbrushes with a traditional longitudinal head, manufacturers recommend additional sweeping movement.• The Oral-B electric brush is extremely delicate for gums. All thanks to rounded fiber tips, Sensitive mode and Smart Ring function, which thanks to the built-in pressure sensor, will inform us when the pressure on the surface of the teeth and gums is too high, communicating it with red color and slowing head movements.
