Experience our most advanced electric toothbrush: the Philips Sonicare DiamondClean Prestige 9900 with SenseIQ technology.

This top-tier brush elevates our proven sonic performance with intelligent sensing and real-time adaptation for truly personalized oral care.

Our All-in-One A3 brush head is designed for every brushing style. Multi-angle bristles stay effective no matter how you brush—removing up to 20x more plaque, promoting 15x healthier gums in six weeks, and delivering up to 100% more stain removal in less than two days compared to a manual toothbrush.

SenseIQ Technology monitors pressure, motion, and coverage up to 100 times per second. If you’re brushing too hard, the toothbrush automatically reduces intensity to help protect your teeth and gums.

With 62,000 bristle movements per minute, Philips Sonicare provides gentle yet powerful cleaning. Our signature Sonicare fluid action drives water and toothpaste deep between teeth and along the gumline to enhance your clean with every session.
