Abstract
A device for cleaning teeth comprising a stiff plastic filament one section of which is curly in shape. This curly section has a longitudinal axis along which tensional forces lie when tensional forces are applied to stretch the device. This curly section also extends laterally to provide contact lines which are oriented at an angle with respect to the longitudinal axis to scrape away unwanted materials on the surface of the teeth when the curly section is pulled longitudinally through the interdental areas. The device can be fabricated by winding a filament around metal pin, heating the filament, and then cooling the filament to provide the curly shape.
