This toothbrush provides a Curaprox brushing experience: 3960 Curen filaments are gentle on the gums and offer excellent cleaning performance. The Curen filaments have a diameter of 0.12 mm. Important: Colors may vary. Curaprox toothbrushes not only prevent brushing damage but also effectively disorganize and remove plaque. Curen bristles are stiffer than nylon and remain stable in the mouth just as they do when dry. These properties allow for the production of toothbrushes with a very high number of very fine bristles. The CS toothbrushes from Curaprox remove and disorganize plaque significantly more thoroughly, thanks to the extremely dense bristle field.
