See all benefitsClean 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.
Click on the TongueCare+ tongue brush to gently remove odor causing bacteria from the pores of your tongue. Its 240 specially designed MicroBristles get between all your tongue's ridges and grooves to remove bacteria and debris that lead to bad breath. Team with our antibacterial BreathRx tongue spray for superior cleaning and super fresh breath.
DiamondClean Smart comes with five modes which cover a range of brushing needs: Clean mode is for exceptional daily cleaning, White+ is for removing stains, Deep Clean+ gives you an invigorating deep clean, Gum Health provides a gentle yet effective clean for gums, and Tongue Care is the perfect mode for cleaning your tongue. It breaks up tongue debris and sweeps away bad-breath bacteria. Three intensities allow you to choose between a higher setting to boost your clean and a lower one for more-sensitive mouths.
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.
You'll enjoy two weeks of regular use from a single full charge. However, if you run low while traveling, your deluxe USB travel case doubles as a charger. Place your toothbrush in the case and either connect it to your laptop or a wall socket. As for charging at home - simply place your brush in your sleek charger glass - it fits stylishly into your bathroom and also doubles as a rinsing glass.
