Head for an oral care implement

A toothbrush head for an oral care implement comprising:

• 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, and the filaments of the at least first row of tufts extending 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 comprising at least one wave crest and at least one wave trough located between a first tuft and a last tuft of the at least first row of tufts, wherein the upper top cleaning surface has a concave topography with respect to the mounting surface of the head to contribute to the continuous wave-shape of the upper top cleaning surface and the tufts of the at least first row are inclined with respect to the mounting surface;
• at least a second row of tufts comprising a plurality of filaments, the second row being substantially parallel to the first row, and the filaments of the second row extend from the mounting surface in different length extensions thereby defining with the filaments' free ends an upper top cleaning surface in the form of a continuous wave-shape comprising at least one wave crest and at least one wave trough located between a first tuft and a last tuft of the at least second row of tufts, wherein the tufts of the second row are arranged such that the at least one wave crest of the at least a second row of tufts is contra-cyclical with respect to at least one wave trough of the at least a first row of tufts, the tufts of the at least second row are inclined with respect to the mounting surface, and the contra-cyclical is a phase shift between the first row and the second row.
