Claim:
1. A toothbrush head, being connected to or connectable to a toothbrush grip handle to thereby define a head-grip handle longitudinal direction, the head being elongate in the longitudinal direction and having a width direction across the head perpendicular to the longitudinal direction, the head having a bristle surface from which inclined plural tufts of bristles extend, the plural bristle tufts comprising; at least four rows of first tufts arranged in a longitudinal direction along the bristle surface, the at least four rows of tufts having two outer rows of tufts proximate to the periphery of the head and at least two inner rows of tufts within the outer rows of tufts, wherein the outer rows of tufts are inclined in a direction having a longitudinal component at 75-85° to the bristle surface such that the ends of the bristles remote from the bristle surface are longitudinally further from the handle than the ends closest to the bristle surface, and wherein the inner rows of tufts are inclined in a direction having a longitudinal component at 75-85° to the bristle surface such that the ends of the bristles remote from the bristle surface are longitudinally closer to the handle than the ends closest to the bristle surface, wherein the outer rows of tufts comprise tufts containing non-tapered bristles having a first greater length LN wherein at least one tuft in the outer rows of tufts and/or at least one tuft from the inner rows of tufts contains both tapered and non-tapered bristles and all the tapered bristles contained in said tufts have the same length LT greater than the greater length LN
