A dental implement includes a wire member that forms a generally ring-shaped portion and first and second ends, which depend from the ring-shaped portion. The ring-shaped portion lies in a plane, with the first and second ends depending from the generally ring-shaped portion in a direction generally orthogonal to the plane. At least a portion of the first end touches at least a portion of the second end when in an initial resting state, wherein the first and second ends generate an inward force towards each other when separated. |
