The Oral-B Pro Precision Clean brush head adapts perfectly to every tooth and removes up to 100 % more plaque than a manual toothbrush. The original Oral-B brush heads have been developed with new X-shaped bristles, which now also clean the areas that normal bristles cannot reach. The green indicator bristles turn yellow over time depending on individual use, indicating the optimum time to change the brush head - for 100% cleaning power. Guaranteed fit with all Oral-B rechargeable toothbrushes, except Pulsonic and iO.
