  • Patent number: 4041962
    Abstract: An implement for removal of bacterial coating from the interstitial areas of adjacent teeth and for cleaning the crevices between such teeth comprises a handle arranged to be securely held by the hand of the user. A toothpick or the like is preferably tapered and of triangular cross section and is frictionally held at substantially right angles to the plane of the handle in a bushing mounted in a hole through one end of the handle so as to permit the rotation of the toothpick and thereby facilitate its entry between adjacent teeth for cleaning. A bent-up portion of the handle at its opposite end facilitates firm holding and guiding of the implement. Conveniently the bent-up portion is fork-shaped and cooperates with a fastening device on the adjacent portion of the handle for supporting a dental floss tensioned between the ends of the tines of the fork for interdental cleaning supplementary to the use of the toothpick.
