Abstract
An oral care implement having an arrangement of tooth cleaning elements thereon. The oral care implement may include a head extending along a longitudinal axis from a proximal end to a distal end. A plurality of tooth cleaning elements extend from the head and are arranged in groups including a first group of tooth cleaning elements that terminate in distal ends that form a concave cleaning surface and a second group of tooth cleaning elements that terminate in distal ends that form a convex cleaning surface. Furthermore, there may also be a third group of tooth cleaning elements extending transversely across the head and dividing the first group of tooth cleaning elements into first and second subgroups of tooth cleaning elements. The third group of tooth cleaning elements may be inclined relative to a surface of the head from which they extend.
