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

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
