Abstract

A head for an oral care implement comprises a mounting surface and at least one tuft extending from the mounting surface. The tuft comprises a first group of filaments and at least a second group of filaments. The first group of filaments is surrounded by the second group of filaments. The filaments of the first group have a longitudinal axis and a cross-sectional area extending in a plane perpendicular to the longitudinal axis, and the cross sectional area has a substantially circular shape with a first diameter. The filaments of the second group have a longitudinal axis and a cross-sectional area extending in a plane perpendicular to the longitudinal axis, and the cross sectional area has a substantially circular shape with a second diameter. The first diameter is smaller than the second diameter. The first diameter is about 0.15 mm to about 0.16 mm, preferably about 0.152 mm (6 mil) and the second diameter is about 0.17 mm to about 0.18 mm, preferably about 0.178 mm (7 mil).
