Abstract
A toothbrush, having a handle and a resiliently flexible bristle-bearing head wherein, when the toothbrush is in its normal stress-free configuration, the free ends of bristles lying along a longitudinal and/or transverse axis of the brush form a generally concave profile adapted to suit the buccal surface of the teeth. The toothbrush head can flexibly conform to a convex profile to suit the labial surface of the teeth or to avoid damage to the gums.
