These deep-clean Philips Sonicare toothbrush heads are designed for Sonicare users who refuse to choose between plaque removal and visible whitening. The C3 Two-in-one delivers both in your daily brushing routine with a soft-touch head that enhances the bristle motion to comfortably reach more areas and achieve up to 1000% more plaque removal¹ while feeling gentle on sensitive gums; a cluster of dense bristles at the center works to deliver up to 100% whiter teeth² so you can see and feel the difference in just three days. Behind that dual-action clean is proven Sonicare technology: 62,000 bristle movements per minute sweep away plaque, while Sonicare Fluid Action drives fluid deep between teeth and along the gumline to support gum health over time, with every head clinically tested to meet the highest standard in quality, safety and performance. BrushSync technology tracks brush head wear so the light on the handle turns on when it's time to replace your brush head⁶; blue bristles turn white as a second visual cue, so you always brush at peak effectiveness.
