    Overview

    The Philips Sonicare ProtectiveClean 4500 (HX6823/16) delivers an exceptional balance of powerful cleaning and gentle care, designed specifically to improve gum health by up to 100% compared to a manual toothbrush. With two brushing modes — Clean and Gum Care — it lets you personalise your routine, whether you’re focusing on plaque removal or giving your gums some extra attention.

    The ProtectiveClean 4500 is equipped with a smart Pressure Sensor that alerts you when brushing too hard, protecting sensitive gums and delicate dental work like braces, crowns, or veneers. Its densely packed, high-quality bristles target plaque effectively, while the specially curved power tip ensures even those hard-to-reach back molars get a thorough clean.

    At the heart of this toothbrush is Philips Sonicare’s advanced sonic technology, delivering an astonishing 62,000 brush strokes per minute that pulse fluid between your teeth and along the gumline, breaking up plaque and leaving your mouth feeling exceptionally fresh. With the added BrushSync feature, you’ll always know when it’s time to replace your brush head, keeping your brushing performance at its peak.

    Combined with a long-lasting rechargeable battery and sleek, ergonomic design, the ProtectiveClean 4500 offers a premium brushing experience that elevates your daily oral care routine.
    Up to 100% Better Gum Health

    Specially engineered bristles gently yet powerfully clean along the gumline, removing plaque and improving gum health up to twice as effectively as a manual toothbrush — perfect for reducing inflammation and supporting long-term oral health.

    Two Personalised Brushing Modes

    Choose from Clean mode for everyday plaque removal or Gum Care mode, which adds an extra minute of low-power brushing to gently massage gums and enhance gum health, delivering a fully customisable brushing experience.

    Built-in Pressure Sensor

    Smart feedback system monitors your brushing pressure and provides real-time alerts when you’re pressing too hard, helping you maintain a gentle touch to protect sensitive gums, orthodontic appliances, and dental restorations.

    Advanced Sonic Technology + BrushSync

    Generates up to 62,000 dynamic brush strokes per minute, creating fluid action that pulses water deep between teeth, while BrushSync technology tracks brush head wear and signals when it’s time for a replacement.

    Electric Toothbrush
    It was recommended by my dentist to get an electric toothbrush. Assist with plaque on the glue used in fillings. Initially the vibration was difficult to deal with especially brushing the top teeth. I have been using for a month now. Excellent, my teeth feel cleaner. I will say I think my teeth are now a little more sensitive to cold foods.

    The Most Effective Dental Health Tool
    After years of using OralB electric toothbrushes, I decided to try the Phillips Sonic Care brand. It has certainly proven to be a great choice! My most recent dental check up confirmed that my new cleaning regime, that includes twice-daily use of my new electric toothbrush, has shown substantial improvement
