Philips Sonicare DiamondClean 9000

Brand: Philips Sonicare 9900 Prestige

A sonic brush from the HX9911 family that sweeps rather than spins: the bristles vibrate at high frequency and drive toothpaste and saliva between the teeth. Four modes (clean, white+, gum health, deep clean) each come with three intensity levels, so the brush can be dialled down for receding gums without giving up cleaning time. There is a pressure sensor, a BrushSync chip that logs head wear, and Bluetooth reporting to the Sonicare app. The box normally includes a charging glass and a zip travel case that charges over USB.

A good fit for people who dislike the buzzing of oscillating brushes and for anyone with crowns or veneers, where the gentler sonic action is easier to live with. Those who want a strong scrubbing sensation on the tooth surface may find it too mild, and the charging glass is elegant but a nuisance on a crowded bathroom shelf.
