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.

Guides you to brush and highlights missed areas

Guides you to brush and highlights missed areas

The Philips Sonicare app lets you know when you've achieved a thorough clean, and coaches you to be a better, more mindful brusher.

Guides you to reduce your scrubbing

Guides you to reduce your scrubbing

With an electric toothbrush, you let the brush do the work. We've built a scrubbing sensor into your handle as a gentle reminder to reduce scrubbing. This way, you can improve your technique and get a gentler, more effective clean.

Brush heads automatically select the optimal settings

Brush heads automatically select the optimal settings

Wondering which mode and intensity you should use? Wonder no longer. A microchip in your brush head tells your DiamondClean Smart which one you're using. So if you click on a gum-care brush head, for example, your toothbrush knows to select the optimal mode and intensity to provide a gentle yet effective care for your gums. All you need to do is to press the power button.

Make sure you're getting the most from your brush head

Make sure you're getting the most from 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.

Choose from 5 modes and 3 intensity settings

Choose from 5 modes and 3 intensity settings

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.

Alerts you if you're pressing too hard

Alerts you if you're pressing too hard

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.

Takes you back to any missed spots for 100% coverage

Takes you back to any missed spots for 100% coverage

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.
