BrushSync mode pairing
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 personalised clean every time you brush with our adaptive cleaning technology. Soft rubber sides flex to let C3 Premium Plaque Defence adapt to the shape of your teeth and gums, absorbing any excess brushing pressure and enhancing our sonic cleaning power. Bristles can then adjust to the shape of your teeth and gums so you get up to 4 x more surface contact than a regular brush head** for deeper cleaning in hard-to-reach areas.
You'll always get the best possible clean with our BrushSync™ mode-pairing feature*. The Philips Sonicare C3 Premium Plaque Defence 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 to do is start brushing.

Oh THATS what my teeth are supposed to look like!
The grey lines in the crevices of the tops of my teeth have completely gone after 1 month! And, my poor wisdom teeth right at the back had been completely grey for years ( I have used an electric brush all my adult life), they too are now actually lightening significantly and starting to look like healthy teeth again. I really questioned whether the investment was worth it at first but hands down this is the best toothbrush (Sonicare HX991R 260123 1A) and brush head (C3) combo I’ve ever used. Real results, really quickly.

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
