Philips Sonicare W2 Optimal Black replacement heads are built around a central stain-removal pad of densely-packed, diamond-shaped bristles, designed to lift everyday surface staining from food and drink for visibly whiter teeth in as little as one week, while still removing up to 7 times more plaque than a manual toothbrush.
The click-on design fits any Philips Sonicare handle (except Philips One and Essence/PowerUp Battery models), and if your handle has BrushSync technology, the head will automatically sync to select the optimal brushing mode and intensity for whitening.
No BrushSync handle? Just watch the bristles - they fade from blue to white as your cue to replace the head. Replace every 3 months for the best results.
