    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.

    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.

    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.

    Start taking better care of your trouble areas

    Start taking better care of your trouble areas

    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.

    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.

    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.

    Choose from 4 modes and 3 intensity settings

    Choose from 4 modes and 3 intensity settings

    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.
