The toothbrush comprises an elongated handle having distal and proximal ends and one or more elastomeric handle regions in. A resiliently flexible head is attached to the proximal end of the handle. The head (2) includes a pair of opposing faces, with one of the pair is a bristle-bearing face with bristles attached to and extending from the face. At least one of the pair has one or more elastomer-containing (5), transverse grooves in. One or more elastomer supply channels extends between the elastomeric handle regions and the transverse grooves (9), where at least one of the elastomeric handle regions and the transverse grooves can be filled with elastomer from a single injection point. All of the elastomeric handle regions and the transverse grooves can be filled with elastomer from a single injection point. At least one supply channel extends to the distal end of the handle. The elastomer injection point is located at the distal end of the handle. Both the bristle-bearing face and the opposing face include transverse grooves in. |
