Philips Sonicare 9900 Prestige Power Toothbrush With SenseIQ-Midnight Blue is the most advanced power toothbrush. It enhances the proven sonic technology with intelligence, sensing and adapting for holistic care so you always get it right. As you brush, SenseIQ technology senses pressure, motion, coverage and more up to 100 times per second. It then adapts the intensity if you push too hard. The intelligence of SenseIQ takes the guesswork out of brushing modes, so you can experience effortless care and better brushing over time. Triangular tips and longer bristles clean deep for gums that are up to 15x healthier in just two weeks. All that without ever switching brush heads. Did you know: brush heads become less effective after 3 months of use?, the BrushSync™ feature can remind you when it's almost time for a replacement. While you clean, Philips Sonicare 9900 Prestige uses sensors to detect the pressure you apply, cleaning motion and coverage – up to 100 times per second. The sensors also keep an eye on how long and how often you brush. While you brush, up to 62,000 bristle movements and dynamic fluid action help clean even hard-to-reach areas, leaving your mouth feeling exceptionally fresh and clean. You might not notice when you brush too hard or start scrubbing, but your toothbrush can. The light ring on the end of your handle can gently remind you to ease off the pressure or scrubbing motion. The toothbrush is 18 mm shorter than Diamond Clean and features premium materials to make this luxurious device easy on the eye, and pleasant to the touch. The elegant and compact travel case can be slipped into any bag for carefree convenience while away from home. And for extra ease, it includes an integrated USB-C port, and a USB charging cable, so you can easily recharge the toothbrush without removing it from the case. The Philips Sonicare app is powered by artificial intelligence and works in perfect harmony with the toothbrush. Meanwhile, auto-syncing keeps brushing data up-to-date in the app, even when you don’t brush with the app by your side.
