I had a bracket break off the other day, so I went in to have it replaced. That rear molar is in fine position, so we just cut the wire and left it.
Seeing as my next scheduled appointment was next week we went ahead and put gap springs on the uppers (annoying, but will close the gaps made by closing the sides) and now I am even farther ahead of schedule!
The overbite is nearly gone, which is good also!
So aside from some headaches and general grouchiness due to the teeth moving from the springs, things are progressing well.
