Philips Sonicare DiamondClean Smart 9500 electric toothbrush provides complete and efficient oral care, removing up to 20x more plaque¹, providing up to 15x healthier gums¹ and removing up to 100% more stains than a manual toothbrush. High-performance brush heads let you focus on all areas of your oral health, while our Smart Sensor technology gives you personalized feedback and coaching.

There are 5 brushing modes: Clean mode for daily cleaning, White+ for stain removal, Gum Health for gentle yet effective cleaning of the gums, Deep Clean+ for a refreshing, thorough clean, and Tongue Care for fresh breath. There are also 3 intensity levels to choose from.

The built-in Philips Sonicare light ring pressure sensor lets you know if you’re pressing too hard. Advanced Sonic Technology provides gentle yet effective cleaning, pulsing fluid between teeth and along the gumline with a cleaning power of 62,000 bristle movements per minute.

By connecting to the Philips Sonicare app, you will be able to receive personalized brushing guidance to maintain and improve your brushing habits. The app lets you know when you’ve achieved a thorough clean, and coaches you to be a better, more mindful brusher. The innovative BrushSync™ technology will let you know when it’s time to change your brush head. Improve your brushing technique with QuadPacer, and reach your recommended brushing time of 2 minutes with SmarTimer.

Philips Sonicare DiamondClean Smart 9500 works perfectly as a travel toothbrush thanks to the USB charging travel case. You can also top up the power at home with the iconic charging glass. With regular use, the battery will last up to two weeks on a single charge (based on two periods of two-minute brushings per day on standard mode).
