The special cut for braces. 5,460 filaments are ready on the brush head for daily brace care. The bristles feature a special cut, slightly shortened in the middle, allowing them to surround and clean brackets effectively. Curaprox toothbrushes not only prevent damage from brushing but also optimally disorganize and remove plaque. Curen bristles are stiffer than nylon and remain stable in the mouth just as they do when dry. These properties make it possible to produce toothbrushes with a very high number of very fine bristles.
