Brush without compromise with the A3 Premium all-in-one brush head - our best brush ever. Bristles are angled specifically to remove up to 20x more plaque, even in hard-to-reach areas. Triangular tips remove up to 100% more stains in less than two days and the longer bristles thoroughly clean your gums, making them up to 15x healthier in just two weeks. Complete care without changing brush heads. Did you know that brush heads become less effective after 3 months of use? Our BrushSync™ feature can remind you when it's almost time to change them.

The DiamondClean 9000 gives you the guidance you need to improve and maintain healthy brushing habits between dental checkups. Built-in smart sensors let you know when you're brushing too hard. By connecting your toothbrush to the Sonicare app, you get a personalized progress report that helps you stick to your brushing habits and gives you a record of your improvements.

The DiamondClean 9000 has Clean, White+, Gum Health and Deep Clean+ modes for all your brushing needs. The Clean brushing mode is designed for exceptional daily cleaning, White+ is for removing tooth stains, Gum Health gently but effectively cleans gums, and Deep Clean+ gives you a refreshing, thorough clean. The toothbrush has three strengths, so you can choose a stronger clean or a gentler one for sensitive mouths.

You may not notice you're brushing too hard, but your DiamondClean 9000 doesn't fail to notice. If you press too hard, the handle will pulse slightly and you'll know to be more careful. Let the brush do the work. 7 out of 10 people found this feature helpful and started brushing their teeth better as a result.

Smart brush heads ensure you use the right mode and strength for the best possible cleaning. For example, if you use the W3 Premium White brush head, your DiamondClean 9000's BrushSync technology automatically pairs your brush head with the White+ mode to help whiten your teeth.

All brush heads wear out over time. That's why it's good to keep an eye on yours, too, to make sure your teeth are still properly cleaned. Our BrushSync technology tracks how long you've been using your brush head and how hard you've been brushing. The BrushSync replacement reminder on your handle and a short beep let you know when it's time to replace your brush head.

Your DiamondClean 9000 will last up to two weeks on a full battery with regular use.
