Abstract

A preferred embodiment of the present invention is directed to an automatic dental flosser having a housing which includes a handle and an operating head. The operating head includes a pair of hollow tines which extend in a first plane. A flossing assembly is operably associated with the operating head for removing debris from between and around teeth. The flossing assembly includes a support member for supporting a flossing material. A first portion of the support member is disposed in the hollow tines while a second portion of the support member is removed therefrom. A drive member is operably associated with the first portion of the flossing assembly for linearly displacing the support member. A stop is provided intermediate the upper and lower surfaces of the hollow tines for regulating the proximity of the flossing material to the oral tissues of an individual. Further, an adjustable protective cover encases the second portion of the support member which is removed from the hollow tines.
