Get a clean as unique as your smile. Our Premium plaque control adapts to the contours of your teeth and gums thanks to soft, flexing sides that give you 4x more surface contact than a regular brush head** for a comfortable, deep clean.
And thanks to its flexible design, it removes up to 10x more plaque from hard-to-reach areas* for a truly deep clean along the gum line and between teeth.
You get a personalized clean every time you brush with our adaptive cleaning technology. Soft rubber sides flex to let C3 Premium Plaque Defense adapt to the shape of your teeth and gums, absorbing any excess brushing pressure and enhancing our sonic cleaning power.

You’ll always get the best possible clean with our BrushSync™ mode-pairing feature**. The Philips Sonicare C2 Optimal Plaque Defense brush head syncs with your BrushSync™ enabled Philips Sonicare toothbrush handle**, selecting the optimal brushing mode and intensity level for exceptional cleaning. All you need ...
Philips Sonicare's advanced sonic technology pulses water between teeth, and its brush strokes break up plaque and sweep it away for an exceptional daily clean.
Brush heads become less effective after 3 months of use, but with BrushSync™ you'll be reminded before this happens. Your smart toothbrush will track how often and how hard you brush, and will notify you when it’s time for a replacement. Don’t have a smart Philips Sonicare toothbrush? Just monitor your blue replacement bristles, and when they turn white you’ll know it’s time for a fresh brush head.
All Philips Sonicare brush heads are safe and gentle on teeth and gums. During tests, each brush head is put through its paces to ensure durability and an exceptional performance every time you brush.

Great toothbrush heada
These were replacements for my Phillips electric toothbrush, they last a really long time meaning great value for money. I certainly feel the difference since I’ve started to use this toothbrush and my teeth are cleaner and less stained. Highly recommended.

Superior clean brush heads
These brush heads are great. I tested these in place of my usual brush heads and I could definitely see and feel a difference. The power tip really gets into those hard to reach areas whilst still being soft enough on the gums
Pros
Quality, power tip, easy to use

Best Brush Head I’ve Ever Used – Worth the Upgrade
I’ve been using Sonicare toothbrushes for years, but switching to the C3 Premium Plaque Defence brush head made a noticeable difference almost immediately. My teeth feel cleaner, smoother, and fresher after every brush – like that just-left-the-dentist feeling. The bristles are firm but not harsh, and they contour really well to my gum line and the hard-to-reach areas in the back. I also love the way it adapts to pressure – it feels like it’s doing the work for me without being abrasive. What really impressed me is how much plaque it removes compared to the standard heads. After just a few days, my mouth felt significantly cleaner, and even my dental hygienist noticed the improvement at my last visit. It’s a bit pricier than the basic heads, but honestly, the performance and results make it 100% worth it. If you care about your oral health and want to take your brushing to the next level, this is the way to go. Highly recommend!
Pros
Great plaque removal, colour coordinated, excellent reach
Cons
Little more expensive
