The Curaprox CS Smart is smaller - yet bigger. Developed for children over the age of 5, our CS Smart children's toothbrush looks just like the CS 5460 ultra soft adult's toothbrush. Actually it is somewhat smaller - yet in one respect somewhat bigger. The adult version has 5460 individual ultrafine Curen filaments - at which the CS Smart can only smile, because it has an incredible 7600 Curen filaments and these are even finer, with a diameter of only 0.08mm. Hardly surprising that children aren't the only ones who love the fineness of the CS Smart. Dental professionals who tested them are simply delighted - and recommend adults try them too.
