    Overview

    The Philips Sonicare DiamondClean 9000 (HX9912/63) is the pinnacle of sonic toothbrush design, delivering exceptional cleaning power, advanced personalisation, and elegant style. Engineered to remove up to 20x more plaque than a manual toothbrush, it comes equipped with the A3 Premium All-in-One brush head, designed to lift up to 100% more stains in under two days and improve gum health up to 15x in just two weeks — all without switching heads.

    Its four custom modes (Clean, White+, Gum Health, Deep Clean+) and three intensity settings let you tailor every brushing session to your needs, whether you’re chasing that perfect white smile or prioritising deep gum care. The built-in smart sensors and Bluetooth connectivity sync with the Sonicare app to track your brushing, providing personalised guidance, real-time feedback, and progress reports that help you build healthier habits between dental checkups.

    The DiamondClean 9000 doesn’t just clean — it transforms your brushing experience. A gentle pressure sensor protects your gums, while smart brush head recognition and BrushSync ensure you’re always brushing at peak performance. Wrapped in a sleek, modern design and paired with a convenient travel case, it’s the ultimate oral care companion for a whiter, healthier smile that lasts.
    A3 Premium All-in-One Brush Head

    Angled bristles remove up to 20x more plaque, triangular tips lift 100% more stains in two days, and longer bristles clean deep for gums that are 15x healthier in just two weeks — all without swapping heads.

    Four Cleaning Modes + Three Intensities

    Personalise your brushing with Clean, White+, Gum Health, and Deep Clean+ modes, paired with adjustable intensity settings that let you choose a powerful deep clean or a gentle touch for sensitive areas.

    Connected Smart App + Progress Reports

    Bluetooth connectivity links to the Sonicare app, providing personalised brushing feedback, habit coaching, and progress reports that help you improve technique and track your oral health journey over time.

    Smart Sensors + BrushSync Technology

    Built-in pressure sensors protect your gums by alerting you when brushing too hard, while BrushSync recognises brush heads, adjusts settings accordingly, and reminds you when it’s time to replace.

    Do not buy!!
    Purchased this brush 3 months ago. I went to change the head because it was due and when I put the new one on it doesn’t brush anymore. Same brush head made by Phillips. I’ve been a Sonicare user for over 16 years and this is the worst experience yet! Do not buy!

    It's okay.
    I have had for a few months now and it's good but not so good at removing yellowing of the teeth.

    Excellent
    I had my old diamond clean for just over 7 years and then it stopped working. I purchased a cheaper brands model to get by until the Diamond Clean went on sale. I persevered with this cheaper model and finally the Diamond Clean was on sale. This new model is so much better than the old model! Although I am not bothered about using the app its a function that some people would find fun to use.
