The Philips Sonicare C2 Optimal Plaque Defence toothbrush head is perfect for those who want to maintain optimal plaque removal as part of their everyday oral healthcare routine.

Say goodbye to plaque
Densely-packed, high-quality bristles remove up to 7x more plaque than a manual toothbrush. And the specially curved power tip makes reaching the teeth at the back of your mouth a breeze.

Brush head replacements
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. 

The only true sonic technology
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.

Brushing with peace of mind
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.

BrushSync™ mode-pairing
You’ll always get the best possible clean with our BrushSync™ mode-pairing feature**. The Philips Sonicare C2 Optimal 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.
