Oral-B's enhanced Precision Clean toothbrush heads are developed with CleanMaximiser technology, which colors green bristles yellow when it's time to replace the brush head, to ensure the best results from the brush head and the best toothbrushing. The unique bristles remove plaque and provide a superb cleaning compared to a regular manual toothbrush. Can be used with all Oral-B handles except Pulsonic & iO.
