Key features:
All-in-One brush head for complete care
Clean without compromise with the A3 Premium All-in-One brush head. Our all-time best has angled bristles to help remove up to 20x more plaque even in hard-to-reach areas1. Triangular tips work to remove up to 100% more stains in less than two days2. And longer bristles clean deep for gums that are up to 15x healthier in just two weeks3.
Start and keep up healthy habits
The DiamondClean 9000 gives you the guidance you need to improve and maintain healthy brushing habits in between dentist checkups. Built-in smart sensors let you know when you're using too much pressure, and by connecting your brushing experience to the Sonicare app, a personalized Progress Report helps you stay on track, to see how much you've improved over time.
Lets you know if you're pressing too hard
You might not notice if you're brushing too hard, but your DiamondClean 9000 will. If you need to ease up, the toothbrush will make a pulsing sound. It's a heads up to let your brush head do the work. 7 out of 10 people found this feature helped them become a better brusher.
BrushSync automatically selects the best mode for you
Smart brush heads ensure you're using the right mode and intensity for the best possible clean. For an example, say you're using the W3 Premium White brush head. Your DiamondClean 9000's BrushSync technology will automatically sync your brush head with the White+ mode to help whiten your teeth.
Always know when to replace your brush heads
All brush heads wear out over time, so you'll want to keep an eye on yours to make sure you're still getting a great clean. Our BrushSync technology tracks how long you've been using your brush head for, and how hard you've been brushing. The BrushSync replacement reminder on your handle and a short beep gives you a heads up when it's time to replace it.
