Philips Sonicare 9300 DiamondClean Smart Electric Toothbrush

The Philips Sonicare DiamondClean Smart 9300 is a high-performance, app-connected sonic electric toothbrush engineered to maximize plaque removal, gum health and stain reduction through optimized sonic energy, intelligent sensor feedback and proprietary brush-head recognition. It combines 62,000 bristle movements per minute with multi-mode cleaning, pressure feedback and personalized coaching via the Sonicare app for measurable oral-health improvements.

Key Features:

• Sonicare Fluid Action – 62,000 movements/min: High-frequency sonic motion drives fluid between teeth and along the gumline for effective mechanical + fluid cleaning.

• Clinically relevant performance claims: Up to 20× more plaque removal and up to 15× healthier gums vs. a manual toothbrush (manufacturer data).

• Smart sensor system: Visual pressure sensor (light ring + vibration) alerts when excessive force is applied to protect gums.

• Brush-head detection & replacement reminders: Device recognizes the attached head (A3 All-in-One, C3 Plaque Control, etc.) and adapts or reminds replacement for consistent performance.

• Four modes & three intensities: Clean, White+, Gum Health, Deep Clean+ plus Low/Medium/High intensity to tune mechanical action for sensitivity or deeper cleaning.

• App connectivity & real-time coaching: Bluetooth pairing with Sonicare app gives coverage mapping, pressure/motion feedback, progress tracking and personalized guidance. Independent reviews highlight the app as valuable for technique improvement.
