A flossing tip (22) for a power dental flossing device (20) is elongated and includes a base portion (74), a central portion (76) having a generally rectangular cross-section, and an enlarged end portion (70) including a disk shape (72). The tip (22) is compressible. The base portion (74) supports the tip (22) when the tip (22) is coupled to the dental flossing device (20). The central portion (76) couples the base portion (74) to the end portion (70). The end portion (70) is inserted between a pair of adjacent teeth (24A, 24B) of a user and helps guide and orient the tip (22) between adjacent teeth (24A, 24B). When in use, the rectangular cross-section of the tip (22) provides multiple points of contact against a tooth for cleaning and also helps maintain the tip (22) in proper orientation with respect to the teeth. The enlarged end portion (70) assists in positioning the tip (22), provides additional cleaning edges, and helps prevent trauma to the gums.
