Abstract

A toothbrush includes a handle, a head extending from the handle, and a tuft of bristles extending from the head. The tuft is inclined such that the angle of inclination is an acute angle relative to a surface of the head through which the tuft extends. The bristles have free ends which define a plane, the plane being other than perpendicular to a direction in which the tuft extends from the head. The plane is inclined towards the same direction in which the tuft is inclined.
