The C1 ProResults are soft on teeth and gums, but effective on plaque, removing 2x more plaque than a manual toothbrush. Its innovative brush head with its contoured profile is designed to mirror the contours of the surface of your teeth, to deliver a gentle yet effective cleaning experience. 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.

All brush heads are interchangeable with any Philips Sonicare toothbrush.

Brush heads become less effective after 3 months' 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 — when they turn white you'll know it's time for a fresh brush head. Once you’ve finished with your used brush head, all Philips Sonicare brush heads are recyclable with TerraCycle.
