Compatible with ALL Philips Sonicare handles, including DiamondClean and ProtectiveClean. Achieve whiter teeth in just 1 week vs a manual toothbrush. Stain-removal pad, made from densely-packed diamond-shaped bristles, removes surface stains caused by food and drink. BrushSync technology ensuring compatibility with a BrushSync enabled Philips Sonicare electric toothbrush. Always know when to replace. Always get an effective clean. Brush heads become less effective after 3 months' use, but with BrushSync™ you'll be reminded before this happens. Your smart toothbrush will track how often and how hard you brush and will notify you when it's time for a replacement. Don't have a smart Philips Sonicare toothbrush? Just monitor your blue replacement bristles — when they turn white you'll know it's time for a fresh brush head.
