Get a clean as unique as your smile. The C3 Premium Plaque Defence adapts to the contours of your teeth and gums thanks to soft, flexing sides that give you 4x more surface contact than a regular brush head for a comfortable, deep clean. Thanks to its flexible design, it removes up to 10x more plaque from hard-to-reach areas for a truly deep clean along the gum line and between teeth. You get a personalised clean every time you brush with Philips adaptive cleaning technology. Soft rubber sides flex to let C3 Premium Plaque Control adapt to the shape of your teeth and gums, absorbing any excess brushing pressure and enhancing the sonic cleaning power. Bristles can then adjust to the shape of your teeth and gums so you get up to 4x more surface contact than a regular brush head for deeper cleaning in hard-to-reach areas. You'll always get the best possible clean with Philips BrushSync mode-pairing feature. The Philips Sonicare C3 Premium 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. Your C3 Premium Plaque Defence 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. All Philips Sonicare brush heads are safe and gentle on teeth and gums. During tests, each brush head is put through its paces to ensure durability and an exceptional performance every time you brush. Your Sonicare brush head and handle are the ultimate team. Enhancing Philips sonic technology, they give you unrivalled cleaning. High-speed vibrations in your toothbrush handle power up to 62,000 brush movements per minute that whip up your toothpaste into gentle cleaning bubbles, driving them deep between your teeth and along the gum line for exceptional cleaning.
