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 areas*. Triangular tips work to remove up to 100% more stains in less than two days***. 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? Our BrushSync feature can remind you when it's almost time for a replacement.
Brush away plaque with sonic technology – our benchmark in effective and gentle cleaning. While you brush, up to 62,000 bristle movements and dynamic fluid action help the bristles clean even hard-to-reach areas, leaving your mouth feeling exceptionally fresh and clean.
With DiamondClean Smart you get the full works. Our 3 intensity settings let you boost your clean, and our 4 modes cover all your brushing needs; Clean mode for exceptional daily cleaning, White+ to remove stains, Deep Clean+ for an invigorating deep clean, and Gum Health to gently clean along your gum line.
The Philips Sonicare app lets you know when you've achieved a thorough clean, and coaches you to be a better, more mindful brusher.
If you happen to miss a spot while brushing your teeth, your app's TouchUp feature will show you. You can then go back for a second pass, and be confident you are getting a complete clean, every time.
Any trouble areas your dentist has pointed out? We'll highlight them on your in-app 3D mouth map, and remind you to pay extra attention to these areas.
With an electric toothbrush, it's best to let the brush do the work. We've built a sensor into the handle that works with our app to help you reduce excess scrubbing. This way, you can improve your technique and get a gentler, more effective clean.
You might not notice when you brush too hard, but your DiamondClean Smart will. If you use too much pressure, the light ring on the end of your handle will flash. This is a gentle reminder to ease off the pressure, and let your brush head do the work. 7 out of 10 people found this feature helped them become a better brusher.
You'll always get the best possible clean with our BrushSync mode-pairing feature. Smart brush heads ensure you're using the right mode and intensity for the best possible clean by selecting the optimal brushing mode and intensity level in combination with your brush head.
Brush heads wear-out over time and become less effective at removing plaque. With smart brush head recognition you'll never lose track of when to replace your brush head. Your toothbrush tracks how long and hard you've brushed with each brush head, and will alert you when it's time to replace. You can also monitor the lifetime of your brush heads in the Philips Sonicare app, and even order replacements so you're never caught short.
You get a personalized clean every time you brush with our adaptive cleaning technology. Soft rubber sides flex to let C3 Premium Plaque Control adapt to the shape of your teeth and gums, absorbing any excess brushing pressure and enhancing our sonic cleaning power. Bristles can then adjust to the shape of your teeth and gums so you get up to 4x more surface contact than a regular brush head**** for deeper cleaning in hard-to-reach areas.
Charging a toothbrush has never been so effortless. Simply place your toothbrush into the sleek glass holder after brushing, and it instantly starts charging. Not only does your glass charge fit stylishly into your bathroom, it also doubles as a rinsing glass. Enjoy two weeks of regular use from a single full charge. Our premium travel case lets you store your toothbrush hygienically when you're on the go.
