The Philips Sonicare HX6062/88 replacement brush heads from the Optimal White series are designed for adults looking to brighten their smile. These black, oval-shaped heads feature medium-stiffness bristles that focus on removing stains and whitening teeth, with clinical evidence showing they can remove up to 100% more stains than a manual toothbrush. You can expect to see visible whitening results after just one week of regular use. These heads are compatible with all Philips Sonicare electric toothbrushes and include BrushSync technology, which provides a visual indicator to remind you exactly when it is time to replace the head for maintained effectiveness.
