Patent attributes
A head for an oral care implement has at least a first row of tufts including 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. The filaments of the longest length extension have a cross-sectional area being smaller than the cross-sectional area of the filaments of the shortest length extension.
