Abstract
An interdental toothbrush has a handle made from a mixture of a thermoplastic elastomer and a general purpose polypropylene. A twisted wire brush projects from the handle in axial alignment therewith. The toothbrush can be held within a loosely clasped fist, with one end of the brush held between a thumb and an index finger. By manipulating the thumb and index finger, the angle at which the brush projects may be changed at will. In this way, the insertion of the brush in more difficult to reach spaces in or around teeth is more easily performed.
