A toothbrush featuring a graspable elongated handle defining a longitudinal axis, the handle comprising a neck region adjacent an end of the handle and a head disposed at the end of the handle. The head is carrying flexible bristles that extend outward from an outer surface of the head. The outer surface of the head is axisymmetric. The bristles are distributed about the head such that bristles extend in each of several radial directions, including from opposite sides of the head. At least some of the bristles are extending so as to overlay the longitudinal axis in opposite directions.
