Abstract

A head for an oral-care implement having a longitudinal axis and comprises a bristle carrier having at least one tuft hole and at least one tuft being fixed in said tuft hole by an anchor. The at least one tuft comprises at least one filament having a longitudinal axis and a non-circular cross-sectional area extending in a plane substantially perpendicular to the longitudinal axis. The at least one filament is bent around the anchor so that a first limb and a second limb extend from the bristle carrier. The first limb comprises a first free end, and the second limb comprises a second free end. Each free end is twisted around the longitudinal axis by a twisting angle α of about 80° to about 100°, preferably about 90°.
