Abstract
A toothbrush has a handle provided with a rigid curve wire axle at one end. A hollow shank and toothbrush head rotatable and snugly fit to the axle. In the configuration shown bristles on the head are concave. The bristle formation can be made convex by rotating the shank on the axle by 180.degree.. This enables the bristle formation to be concave (as shown) or convex, and adopt configurations in between as desired by a user where the curvature is less concave (or less convex) by rotating the head to intermediary relative positions on the axle
