Philips DiamondClean Smart 9900 HX9954/52 Electric Toothbrush: Smart connectivity
This Philips Sonicare DiamondClean Smart 9900 is for anyone tired of guessing if they're brushing effectively, like busy professionals or parents ensuring their kids' oral health. While most electric toothbrushes focus on cleaning power, this one offers a personal coach for your smile, turning routine into a guided habit.
The app tracks your brushing in real-time, so you see exactly which areas you missed—no more relying on memory. It connects seamlessly with Alexa for hands-free control, and the pressure sensor gently alerts you before you brush too hard. You'll notice your dentist appointments become quicker and more positive, with fewer reminders about technique.
