1. A toothbrush head having a tip end and a base end, the base end being connected or connectable to a toothbrush handle and having a longitudinal direction between the tip end and base end, having a widthways direction perpendicular to said longitudinal direction and having a face having widthways opposite edges, and having an elastomeric oral hygiene part mounted on the face, the elastomeric oral hygiene part comprising an adjacent pair of elastomeric strips which each project from the face of the toothbrush head in a strip length direction, each elastomeric strip having a strip width direction generally perpendicular to the strip length direction the strip width dimension being less than the strip length dimension, and a strip thickness direction generally perpendicular to both the strip length and strip width direction, the strip thickness dimension being less than the strip width dimension,
wherein two said adjacent strips are linked such that the pair of strips comprise a single elastomeric oral hygiene part with a cross section, cut across the strip length direction, which is chevron shaped comprising said strips converging to meet at an apex, the strips converging in a direction transverse to the longitudinal direction of the head to define an angle of less than 180° between them, and wherein plural said elastomeric oral hygiene parts are arranged on said face sequentially longitudinally and adjacent to said widthways opposite edges with the apex of the chevron shape pointing inwardly away from said widthways opposite edges of said face.
