Feature
Features The DiamondClean Smart provides a deep clean for a whiter, healthier smile. High-performance brush heads let you focus on all areas of your oral health and our Smart Sensor technology gives you personalized feedback and coaching.

All-in-One brush head for complete care
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.

Sonic brushing: the masterclass in effective cleaning
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.

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.

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