<p>A toothbrush (2) having a head (3) and a handle, the head having spaced tufts (4) of filaments (6) arranged in transverse rows, which is characterised in that the tufts (4) in each row between the two end tufts are substantially all generally quadrilateral in cross-section with one pair of sides substantially parallel to the row and are spaced close to adjacent tufts so as to form a blade-like array of filaments across the brush head. The invention also relates to a toothbrush as described above in which the filaments (6) in each tuft (4) are generally rectangular in cross-section with one pair of sides generally parallel to the row. <IMAGE></p> |
