    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.

    The Philips Sonicare toothbrush whitens teeth 2x better than a manual model, removing up to 100% more stains in a single week. The AirFloss Ultra makes flossing your teeth and cleaning harder-to-reach areas, almost effortless. 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. 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. With the AirFloss Ultra, you can completely floss in just 60 seconds a day.
    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.

    Whiter Smile

    Gently polishing your teeth and removing surface stains while you brush, this toothbrush will leave you with a whiter, brighter smile from the very first day of use.

    Love the squirt action
    I use it every day three times to clean under my bridges - wouldn't be without it. Now it has stopped working and out of warranty. Please Philips why are they not available anymore?
