Philips Sonicare C2 Optimal Plaque Defence(formerly ProResults plaque control)

Densely-packed, high-quality bristles remove up to 7 x more plaque than a manual toothbrush. And the specially curved power tip makes reaching the teeth at the back of your mouth a breeze.

You'll always get the best possible clean with our BrushSync™ mode-pairing feature**. The Philips Sonicare C2 Optimal Plaque Defence brush head syncs with your BrushSync™ enabled Philips Sonicare toothbrush handle**, selecting the optimal brushing mode and intensity level for exceptional cleaning. All you need to do is start brushing.

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.
