A flat brush head can lose contact as it curves around back molars and along the gumline. The C3 Premium Plaque Defence has soft, flexible rubber sides that bend with the shape of your teeth, so bristles stay pressed against the surface where plaque actually sits.
In the centre, a pentagonal cluster of dense, stiff bristles works on surface stains from coffee, tea, and red wine, lifting them over a few weeks of regular use. The flexible sides also absorb the extra pressure if you tend to push too hard, which keeps brushing comfortable on sensitive gums. That two-job approach - flex plus stain-lifting cluster - is what separates the C3 from a basic plaque control refill.
Blue indicator bristles fade to white with use, giving a clear visual cue for when to swap. BrushSync technology also pairs with the Sonicare app to let you know when to replace your brush head. The black finish sits flush against darker handles for a tidy match.
How to Use:
- Click the old brush head off your toothbrush
- Push the new brush head onto the top of the handle until it clicks into place
- Brush for two minutes daily (30 seconds each quarter of your mouth)
- Rinse the brush head and handle after use
- Replace the brush head every three months, or when bristles start to fray
