Abstract
The invention is directed to a bristle (1) for a toothbrush, in particular for an electric toothbrush, which is comprised of a monofilament (2) made of plastic. The monofilament (2) is of a non-circular cross-section, is twisted about its longitudinal axis, and is fixed as a result of the action of chemical agents. In this manner, the bristle (1) is provided with a three-dimensionally structured surface which effects an improved cleaning action, in particular with regard to the removal of plaque.
