<p>A toothbrush (10) provides a bi-angled handle (12) member generally defining a primary longitudinal axis (14), a brush head member (30) pivotable about the handle member (12) on a brush head axis, and carrying downwardly-depending brush bristles (44) defining a bristle axis (46), such that the brush head axis is generally perpendicular to both the handle member (12) longitudinal axis (14) and the bristle axis (46). The handle member (12) terminates in a first end enabling brush head (30) rotational movement only about the brush head axis.</p> |
