The Philips Sonicare Protective Clean, with unique sonic technology, sweeps away plaque giving you an amazingly effective, yet gentle clean. Our built-in pressure sensor lets you know if you're brushing too hard, to help protect your teeth and gums. This electric toothbrush allows you to customize your brushing with a choice of three modes and three intensities. Clean mode is standard for superior cleaning. White mode is the ideal mode for removing surface stains. Gum Care mode adds an extra minute of reduced-power brushing, so you can gently massage your gums. Three intensities allow you to choose between a higher setting to boost your clean and a lower one for more-sensitive mouths.
