  • Patent number: 6609910
    Abstract: A flossing tip for a power dental flossing device. The tip is elongated and includes a base portion, a central portion having a generally rectangular cross-section, and an enlarged end portion including a disk shape. The tip is compressible. The base portion supports the tip when the tip is coupled to the dental flossing device. The central portion couples the base portion to the end portion. The end portion is inserted between a pair of adjacent teeth of a user, and helps guide and orient the tip between the adjacent teeth. When in use, the rectangular cross-section of the tip provides multiple points of contact against a tooth for cleaning, and also helps maintain the tip in proper orientation with respect to the teeth. The enlarged end portion assists in positioning the tip, provides additional cleaning edges, and helps prevent trauma to the gums.
