Philips Sonicare HX9331/04 DiamondClean Rechargeable Toothbrush, White

Never knowingly undersold

Product information

Introducing the Philips Sonicare DiamondClean rechargeable sonic toothbrush to help you remove up to 100% more plaque from those harder-to-reach places, whitening teeth twice as well as a manual toothbrush in a single week. As well as polishing and cleaning teeth, the brush also helps to improve gum health by cleaning deep between teeth and right along the gumline.

Featuring Sonicare's most effective tooth-whitening brush, thanks to its medium-stiffness and diamond-shaped bristles which scrape away plaque effectively whilst being gentle on your teeth. The toothbrush features a sensitive mode to ensure you are extra gentle to your gums.

A Quadpacer interval timer indicates when you have spent enough time brushing each quadrant of your mouth and should move onto the next to ensure your brushing is consistent throughout.

There are two charging options - a charger glass which can also be used for rinsing your mouth, and which you can use at home by placing the toothbrush into it. There is also a travel charging case which can be charged via a USB port or wall socket so you can take your DiamondClean toothbrush with you wherever you go.
