Abstract
A head for an oral care implement comprises at least a first row of tufts comprising a plurality of filaments having free ends and fixed ends being opposite the free ends and being fixed on a mounting surface of the head. The filaments of the at least first row of tufts extend from the mounting surface of the head in different length extensions thereby defining with the filaments' free ends an upper top cleaning surface in the form of a continuous wave-shape. Each filament has a longitudinal axis and a cross-sectional area extending in a plane that is perpendicular to the longitudinal axis. Each tuft of the at least first row comprises either filaments with a smaller cross-sectional area or filaments with a larger cross-sectional area, and the tufts are arranged in an alternating manner so that a tuft comprising filaments with the smaller cross-sectional area alternate with a tuft comprising filaments with the larger cross-sectional area.
