Important: Colours vary Curaprox toothbrushes not only prevent brushing damages, but also break up and remove plaque perfectly. Curen-filaments are stiffer than nylon and remain just as stable in the mouth as when they are dry.

Curaprox CS toothbrushes break up und remove plaque more thoroughly – thanks to the extremely dense bristles.
