I don't believe even orthodontia would help these motley teeth. The "teeth" of a round sawtooth hanger I developed rust away in a pile of almost-scraps. A normal sawtooth hanger is a straight metal strip, an inch or two long, with triangular zigzag teeth cut into one side. The teeth help you to adjust where a piece is hanging, right to left, one tooth at a time, and how level it hangs. My round hanger allows a piece to be rotated 360 degrees on the wall to hang however the client or artist would like. I mostly use them on roundish pieces that can be reoriented in all sorts of ways.
