Philips Sonicare C2 Optimal Plaque Control brush heads are tough on plaque and gentle on gums. Each brush head offers up to 7x more plaque removal than a manual toothbrush. The click-on design provides for simple brush head placement. You'll always get the best possible clean with our BrushSync mode-pairing feature*. The Philips Sonicare C2 Optimal Plaque Control 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 of 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, and when they turn white you'll know it's time for a fresh brush head. Model: HX9023/65.

*BrushSync mode-pairing is only compatible with Philips Sonicare BrushSync enabled toothbrush handles.
