Achieve up to 1000% more plaque removal¹ and 100% healthier gums² with the Philips Sonicare 5900 Series sonic toothbrush combined with the C3 Two-in-one 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. It’s easy to brush too hard, so this sonic electric toothbrush for adults has a smart optic sensor to detect excessive pressure. The sensor lets you know if you’re overdoing it through haptic vibrations. Ease off and your gums will stay protected! 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 Gum Health 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. Did you know that brush heads become less effective after three months? Dental professionals recommend changing your brush head regularly, which is why Philips Sonicare toothbrushes have a brush head replacement reminder. It tracks how often and how hard you brush, then reminds you to replace your brush head once it's time for a new one. Experience up to 21 days of regular brushing after a single charge, bringing a new level of convenience to your brushing routine. ¹ vs. a manual toothbrush ² in Clean mode vs. a manual toothbrush in 2 weeks
