Watch every stroke count with the Philips Sonicare Next-Generation DiamondClean 9900 Prestige, an electric toothbrush that shows you exactly where you’re brushing well, and where you’re not.

• Light ring guidance: A third-generation AI model reads your brushing in real time and lights the handle to flag coverage, pressure, or scrubbing before problems start.
• On-device Mouth Map: That same guidance builds a 12-segment map on the display. It flags any spot you miss for a quick touch-up instead of a guess.
• Smart pressure sensing: SenseIQ eases off automatically when you press too hard, protecting enamel and gums without extra effort.
• Sonicare Fluid Action: Pulsing fluid works with the bristles to loosen plaque between teeth and along the gumline, the areas most brushes leave behind.

Add a rechargeable travel case and glass charging stand, and the 9900 Prestige turns smarter brushing into a daily habit.
