Overview

The Philips Sonicare DiamondClean 9900 Prestige (model HX9990/11) in Champagne is the brand's most intelligent electric toothbrush, combining SenseIQ Technology with an advanced AI app to deliver a fully personalized brushing experience. SenseIQ monitors your pressure, motion, and coverage up to 100 times per second, automatically adjusting intensity when you press too hard — so your gums stay protected without you having to think about it. A discreet light ring at the base provides a gentle visual cue when excess pressure is detected.

The brush delivers up to 62,000 bristle movements per minute. Sonicare Fluid Action drives fluid deep between teeth and along the gumline for a thorough clean that goes beyond the bristle tips. The included A3 Premium All-in-One brush head removes up to 20× more plaque than a manual toothbrush, supports up to 15× healthier gums in six weeks, and achieves up to 100% more stain removal.

Brushing Modes & Settings

With 15 total brushing settings, you can tailor every session to your needs:

• 5 Modes: Clean, White, Gum Health, Deep Clean+, and Sensitive
• 3 Intensity Levels: Low, Medium, High — mix and match with any mode

Pair the toothbrush with the Sonicare app for guided brushing, personalized tips, and oral health tracking that adapts to your habits over time.
