    Overview

    Keeping your mouth and teeth clean is incredibly important for your overall health, with great oral hygiene often leading to a healthier you. But brushing is only half the battle. Be fully equipped for all your oral hygiene needs with the Philips Sonicare DiamondClean Electric Toothbrush and AirFloss Ultra.

    Diamond-shaped bristles remove up to 7x more plaque than a manual toothbrush, for a more effective clean in the same time. Using sonic motion, power is extended from the handle to the tip of the brush head, driving fluid between the teeth and along the gum line. The AirFloss Ultra makes flossing your teeth and cleaning harder-to-reach areas, almost effortless. By directing a mix of air and water between the gaps in the teeth, you can remove built-up plaque, improving the health of your gums. In fact, the AirFloss Ultra has been clinically proven to be as effective as regular floss in terms of gum health.
    Sonic Technology

    Helping you clean where a standard brush cannot reach, Sonic Technology issues gentle vibrations and pulses of water between teeth, making it easier to lift and sweep plaque away.

    Air and Micro-Droplets

    Combining air with mouthwash or water, the AirFloss Ultra effectively and efficiently cleans between the teeth and along the gumline.

    Triple-Burst

    Customise the AirFloss' spray with the choice of single, double, or triple bursts for each press of the activation button.

    7x More Plaque Removal

    By virtue of the densely-packed bristles, and automatic motion, this electric toothbrush can remove up to 7x more plaque than a manual model.
