These pictures were taken before and after AJ got his braces on his top teeth. Now he has them on both top and bottom. They are estimating that he'll need to have them on for about 18 months. He goes on March 4th for his first tightening. Years ago, they used to actually tighten them. Now they replace the wire with one a little less flexible, gradually getting stronger and stronger. I think his teeth have already moved a bit. He was pretty uncomfortable for about three days after he got them, which I remember being pretty typical.
