Healthy teeth start with healthy gums. Take care of yours with our G3 Premium Gum Care brush head. Soft sides flex and adapt to the contours of your gums, giving you 2x more surface contact for superior plaque removal at the gum line. You get a personalized clean every time you brush with our adaptive cleaning technology. Soft rubber sides flex to let Premium Gum Care adapt to the shape of your teeth and gums, absorbing any excess brushing pressure and enhancing our sonic cleaning power. Bristles can then adjust to the shape of your teeth and gums so you get up to 2x more surface contact than a regular brush head for deeper cleaning even in hard-to-reach areas. Thanks to its flexible design, Premium Gum Care removes up to 10x more plaque than a manual toothbrush. It moves to enhance our unique Philips Sonicare cleaning technology so that however you brush, you get an exceptional clean you can see and feel. Philips Sonicare's advanced sonic technology pulses water between teeth and its brush strokes break up plaque and sweep it away for an exceptional daily clean. 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. Your Premium Gum Care brush head fits perfectly with any Philips Sonicare toothbrush handle, except PowerUp Battery and Essence. Simply click on and off for easy replacement and cleaning. You’ll always get the best possible clean with our BrushSync mode-pairing feature. The Philips Sonicare C2 Optimal Clean 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.
