Experience exceptional, fully personalised oral care with the Philips Sonicare DiamondClean Prestige 9900 with SenseIQ technology – our most advanced electric toothbrush.
Our proven sonic technology has been intelligently expanded: SenseIQ detects pressure, movement, coverage and more up to 100 times per second, recognizes your brushing style and adjusts in real time when you brush too hard – for intuitive care of your teeth and gums.
Clean without compromise with the A3 Premium All-in-One Brush Head. Our best brush head yet features angled bristles that remove up to 20x more plaque even in hard to reach areas, with up to 15x healthier gums in just two weeks and up to 100% fewer stains in less than two days – compared to a manual toothbrush.
The Philips Sonicare app is supported by artificial intelligence and works in perfect harmony with the toothbrush. Use them for real-time guidance on pressure, movement, and coverage and get custom optimization suggestions and progress overviews by day, week, and month.
The Sonicare Prestige provides real-time feedback: the handpiece vibrates and the tip glows purple when pressure is too strong or yellow when scrubbing too hard. With 62,000 brush head movements per minute, Sonicare technology drives a flow of fluid deep into the interdental spaces for exceptional daily cleaning.
The Philips Sonicare DiamondClean Prestige 9900 comes with the Prestige USB charging case and a charging station for easy, minimalist charging.
