The Philips Sonicare HX6068/13 W2 Optimal White brush heads in a pack of 8 with diamond-shaped and medium-hard bristles ensure a thorough and gentle cleaning experience. They have a central brush block for removing surface stains from food and drinks, which is framed by densely packed, diamond-shaped bristles. They remove up to 7 times more plaque than a regular manual toothbrush. In addition, thanks to Smart Brush Head Recognition, the brush head synchronizes with Sonicare Smart handpieces and automatically selects the optimal brushing mode and the best intensity for exceptional whitening. The HX6068/13 brush heads are suitable for all Sonicare models (except PowerUp Battery and Essence).
