Achieve 1000% more plaque removal¹ with the Philips Sonicare 6100 Series sonic toothbrush combined with the S2 Sensitive electric toothbrush head. Enjoy a powerful yet gentle clean, even in those hard-to-reach areas. This rechargeable toothbrush uses the Next-Generation Sonicare Technology. The motor adjusts power automatically, so there is zero drop in performance when you reach those harder-to-clean areas. Enjoy a gentle yet effective clean for your teeth and gums with 62,000 bristle movements per minute. Sonicare Fluid Action supports the bristles to clean by driving fluid deep between teeth and along the gumline. A visual pressure sensor at its base gently lets you know if you're overdoing the pressure. Simply ease off when it lights up to protect your gums. Give your clean a boost with 6 brushing settings. Whether you want a little more vigor or a specific focus for your clean, you can have it. Choose between Clean and Sensitive mode, and pick one of three intensity levels. Ace your session time with Sonicare’s cleaning timers. Every 20 seconds, the BrushPacer will prompt you to clean a new area. After 2 minutes, the SmartTimer will indicate your session is complete.
