展开Sensitively cleanse hard-to-reach areas using Plaque Control brushes from Philips Sonicare. These specially formulated brushes remove up to seven times more plaque compared to a manual toothbrush. These brushes have a microchip component that interacts with compatible Philips Sonicare toothbrushes so that the right cleansing programme is automatically selected for ideal brushing results. The Sonicare Optimal also helpfully indicates when three months have passed and it’s time to replace the brush. It’s a plug-in system that’s easy to use and allows for no-nonsense replacement. Optimal Black replacement brushes can be freely combined with all Philips Sonicare toothbrushes.
