ABSTRACT:
A toothbrush includes a bristle head and an elongated handle. The bristle head has an elongated shaft extending therefrom, and an engagement rib formed axially on an external surface of the shaft. An upper portion of the handle has an axial hole which forms an opening in a top end of the upper portion, a radial hole that extends radially therethrough in communication with the axial hole and that forms a mouth at a circumferential wall of the upper portion, and an axial slit that extends along the circumferential wall from the opening to the mouth such that the axial hole is also opened laterally through the axial slit. The handle is made of a material which enables a snug-fit connection of the shaft in the axial hole or the radial hole via the opening or the mouth, when the shaft and the engagement rib on the bristle head are inserted respectively into the axial hole and the axial slit in the handle, or into the radial hole and the axial slit in the handle.
