It has been clinically proven that the Oral-B Vitality 100 Cross Action rechargeable electric toothbrush cleans more effectively than a conventional manual toothbrush. The CrossAction brush design allows you to surround each tooth with bristles positioned at a 16-degree angle. Its 2D cleaning action combines oscillations and rotations for more effective plaque removal compared to a conventional manual toothbrush. The built-in timer on the handle helps you to respect the brushing time of 2 minutes recommended by dentists. This product is designed by Oral-B, the most used toothbrush brand by dentists themselves in the world.
