Product details

The Philips Sonicare DiamondClean Prestige 9900 HX9992/45 is the perfect combination of smart technology, elegant design and unrivalled performance for your daily dental care. This electric toothbrush with sonic technology provides thorough and gentle cleaning, even in hard-to-reach areas, and removes up to 20 times more plaque than conventional manual toothbrushes. The innovative SenseIQ technology analyses pressure, movement and brushing surface up to 100 times per second and automatically adjusts the intensity to optimally protect gums and teeth. A light ring reminds you to reduce the pressure - for a comfortable and gentle brushing experience. The A3Premium All-in-One brush head combines everything in one: precise cleaning, gentle care of the gums and effective removal of discolouration. Triangular bristle tips ensure a visibly whiter smile after just two days, while longer bristles improve the health of the gums. With up to 62,000 brushing movements per minute, the DiamondClean Prestige provides dynamic fluid flow and a fresh, clean mouth feel. Its compact, luxurious design, a high-quality vegan leather travel case and a stylish charging base complete the premium experience of the Philips Sonicare DiamondClean Prestige 9900.
