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 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. 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. 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.
