Bristles designed for your smile
The curved design helps the bristles reach exactly where they are needed. During rigorous development, we created a universal practice that ensures exceptional oral care.

Simple and stylish charging – at home and on the go
You can enjoy regular use for two weeks with a single charge. However, should you run out of power while traveling, the exclusive USB charging carry case doubles as a charger. Place the toothbrush in the case and plug it into your laptop or a wall outlet. And when it comes to charging at home, the elegant cup charger fits perfectly in your bathroom and can also be used as a toothbrush cup.

All-in-One brush head for perfect care
Clean without compromise with the A3 Premium All-in-One brush head. Thanks to its angled bristles, our best toothbrush to date removes up to 20 times more plaque, even from hard-to-reach places*. Triangular bristle tips remove up to 100% more discoloration in just two days***. And the longer bristles thoroughly clean the gums, which become up to 15 times healthier after just two weeks**. All this without having to change the brush heads even once. Did you know that brush heads become less effective after 3 months of use? However, the BrushSync function will remind you shortly before the replacement is due.

Sonic cleaning: the high school of effective brushing
Remove plaque with sonic technology – the benchmark for effective and gentle teeth cleaning. During brushing, up to 62,000 cleaning movements made by the bristles and dynamic liquid cleaning help to clean even hard-to-reach areas, thus ensuring a feeling of extreme freshness and cleanliness in the mouth.

BrushSync automatically selects the mode that suits you best
Intelligent brush heads guarantee that you use the right mode and intensity to achieve the best possible cleaning. For example, let's say you're using a W3 Premium White brush head. DiamondClean 9000's BrushSync technology automatically synchronizes the toothbrush head with White+ mode to help whiten your teeth.

A personalized brushing experience
The DiamondClean 9000 has Clean, White+, Gum Health and Deep Clean+ modes to meet all your brushing needs. The Clean mode is for daily thorough cleaning, White+ for plaque removal, Gum Health for gentle yet effective cleaning of the gums, and Deep Clean+ for refreshing, thorough cleaning. The toothbrush has three strength levels, so you can choose a powerful cleaning or a milder level for sensitive mouths.

You'll always know when to replace your toothbrush head
All brush heads wear out over time, so check the condition of the brush head regularly and make sure you are cleaning it properly. Our BrushSync technology tracks how long you've been using the brush head and how hard you've scrubbed with it. A BrushSync replacement reminder on the handle and a short beep indicate when it's time to replace the head.

It warns you if you brush your teeth too hard
You may not even realize that you are brushing your teeth too hard, but the DiamondClean 9000 does. If you apply too much pressure, the handle will gently pulse, signaling you to brush more gently. Let the toothbrush do the work. 7 out of 10 people found this feature useful and switched to a more suitable brushing as a result.

Change to healthy habits and incorporate them into your daily routine
DiamondClean 9000 guides you to improve and maintain healthy brushing habits. Built-in smart sensors let you know when you're applying too much pressure, and by tracking your brushing with the Sonicare app, you can access a progress report that helps you track how much progress you've made over time.
