Seven days to a 100% whiter smile*. Our Sonicare W2 Optimal White Standard sonic toothbrush head features an innovative stain-removal pad made from densely packed, diamond-shaped bristles. It removes surface stains caused by food and drink. Your Philips Sonicare W2 Optimal White brush head syncs with your BrushSync™-enabled Philips Sonicare electric toothbrush handle**, automatically selecting the optimal brushing mode and intensity level for exceptional whitening. All you need to do is start brushing and you'll get the best possible clean for your teeth. Proven to remove up to 7 x more plaque than a manual toothbrush, W2 Optimal White ensures exceptional care of teeth and gums. Our advanced Philips sonic technology pulses water between teeth, and the brush strokes break up plaque and sweep it away for an exceptional daily clean. This brush head is also great for maintaining brightness between professional whitening treatments. Brush heads become less effective after 3 months so BrushSync™ will track how often and how hard you brush, and your smart toothbrush 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, new brush head. The innovative click-on design allows you to replace and maintain your brush heads simply and easily. * Removes up to 7 x more plaque vs. a manual toothbrush ** BrushSync™ mode pairing is only compatible with Philips Sonicare BrushSync™-enabled toothbrush handles.
