Yes, I have the same issue. I waited until I was an adult to get them. I have had them on for about a year and a half and I am about half way through wearing them. Some adjustments at the orthodontist and what follows are better than others. I only had a few weeks here and there where it was horrible. It was/is hard to develop a base to build from when everything is changing and sore at times. I found it helpful to talk with my orthodontist and sax teacher about this. The orthodontist had me only wear the bands at night so that there was less tension overall and my sax teacher kept an eye on how I was playing so that I did not develop bad habits (which I was doing with the extra tension on the jaw). Other than that, the 2 previous posts suggested doing what I did and played through it. Again, the worst times seemed to be early on when things were moving the most.
