Product details

The Philips DiamondClean 9000 dual-pack sonic toothbrush with app HX9914/57 offers a personalised brushing experience. Both electric sonic toothbrushes are equipped with different cleaning programmes that enable gentle, invigorating or particularly thorough cleaning, as well as removing plaque and protecting the gums. With its intelligent brush heads, the toothbrush automatically selects the appropriate programme and the right intensity level and thus adjusts itself in a personalised way. Its slim and ergonomic design makes it comfortable to hold. As a practical extra, they have an integrated pressure sensor with a vibration function that alerts you if you are brushing too hard.

Up to 10x more plaque removal compared to manual toothbrushes

Gentle cleaning - pressure control warns if too much pressure is applied

4 cleaning programmes, 3 intensity levels, up to two weeks battery life

Automatic brush head recognition and brush head change indicator

Intelligent cleaning control and progress report via app
