I just went through this ordeal. Unfortunately, I found out I had TMJ only after it was activated by having my braces put on. So I spent the last 3 months in constant pain. Definately make sure you get a good knowledgable orthodontist that specializes in TMJ to handle your ortho work. The one I found is H Clifton Simmons III in Nashville TN, but I'm sure that's a bit far for you to go. I would look for one that is certified by the AACP (American Academy of Craniofacial Pain). They have a referral list on their website. Make sure to research the ones near you though, as I found that while some are members they may not deal with TMJ as much as others. The bio pages they have there show what percentage of their work is dealing with TMJ.
