DiamondClean Smart 9500 – Black

Smarter Brushing Starts Here

The Philips Sonicare DiamondClean Smart 9500 (HX9923/11) is engineered for people who take their oral health seriously. Powered by Advanced Sonic Technology delivering 62,000 bristle movements per minute, it pulses fluid deep between teeth and along the gumline for a clean that a manual brush simply can't match — up to 20x more plaque removed, gums up to 15x healthier, and up to 100% more stains eliminated.

Tailor every session with 5 brushing modes — Clean, White+, Gum Health, Deep Clean+, and Tongue Care — paired with 3 intensity levels, so your routine works exactly the way your mouth needs it to. The built-in light ring pressure sensor flashes the moment you press too hard, protecting enamel and gums in real time. Connect to the Philips Sonicare app for personalized coaching, habit tracking, and brush-head replacement reminders via BrushSync technology. QuadPacer and SmarTimer keep your technique consistent and your two-minute sessions on track.

Travel-Ready, Long-Lasting Power

Whether you're home or on the go, charging is effortless — use the sleek USB charging travel case or the iconic charging glass. On a single charge, the battery powers up to two weeks of use based on two two-minute sessions daily on standard mode. The #1 dental professional recommended sonic toothbrush brand worldwide, Philips Sonicare delivers expert-level care in your hands every day.
