Philips Sonicare Cordless Power Flosser 3000

Brand: Philips Sonicare 9900 Prestige

Philips answer to the cordless Waterpik, built around the Quad Stream nozzle that splits one jet into four streams and widens the cleaning zone, so precise aiming matters less around brackets. Two flossing modes and three intensity levels, an IPX7 sealed body for shower use and USB charging. Philips claims up to 150 percent better gum health than string floss in its own testing; model codes run HX3806 and HX3826 depending on nozzle count and colour.

A sensible choice for a first water flosser and for anyone with tender gums early in orthodontic treatment, since the lowest intensity is genuinely soft. The nozzle range is thinner than Waterpik's, with no tapered orthodontic brush, and replacement nozzles are proprietary. Reservoir volume is small, so a full mouth usually means one refill.
