Philips Sonicare 9900

The kind of sound (but not inconsiderable) investment that reassures you as soon as you use it, everyone needs a top-of-the-range electric toothbrush. The Sonicare 9900 is the smartest of the bunch, adapting to your brushing style in real time (adjusting intensity when you go too hard) and comes with five settings and a leather (chargeable) carry case. There’s also a cool app that effectively acts as a game – your teeth are displayed on the screen and they visibly whiten as you clean, as the app guides you to dedicate the same amount of time and attention to each row and section.
