Abstract

A brush head for an oral care implement includes at least one (first) group of tufts extending from a mounting surface of a tuft carrier having a rotation axis. The tufts have a base end and a free end. The tufts of the first group are tufts having an extension in a circumferential direction about the rotation axis exceeding an extension in a radial direction. The tufts of the first group may be inclined with respect to the mounting surface in at least one direction. Each of the first-group tufts may comprise a first group of filaments and a second group of filaments, wherein the second-group filaments' free ends protrude beyond the first-group filaments' free ends.
