ABSTRACT:
A Dental Flosser is described wherein an elongated handle is provided at one end with a bifurcated flosser head including a pair of downwardly extending, spaced and curved arms having concaved and notched extremities to receive a length of dental floss and at the opposite end with the usual tufts of teeth brushing bristles, whereby the one end of the device can be provided with a length of dental floss for use in cleaning food particles and dental plaque from the opposed faces of adjacent teeth, below the free gum margin, and along the margins of dental restorations, and detecting incipient decay of the teeth, and whereby the opposite end can be used for brushing and cleaning the teeth in the usual manner. At the base of the bifurcated head, the device includes a unique floss anchoring button on the top surface and a bulbed fulcrum portion on the bottom surface. The interior tip surface portions of the spaced arms are flared outwardly for safety purposes and protect the gums from injury while the length of floss bridging the bifurcations is engaged between adjacent teeth during the cleaning operation. The spaced arms are further provided with a reduced cross-section adjacent to the base of the bifurcated head to provide more flexibility of the arms and thus, allow a more efficient and complete cleaning of the teeth. Diagonal grooves are provided on the exterior surface of the spaced arms to guide and support the dental floss when it is threaded through the Dental Flosser.
