Hey there...I had arthroscopy done on both sides of my jaw back in 1994. Had braces for two years following the procedure. My teeth didn't touch after wearing splints for two years! I had to wait for six months following my procedure to allow things to settle a bit before they would touch me. I also had to have one tooth pulled, but they wouldn't touch a molar due to making my bite unstable. They pulled one of my front teeth so now I no longer have a center line in the front. It was awful for a few weeks...looked like a poster child for the tooth fairy!
My teeth are in great shape though and following a second arthroscopy in March of this year...they decided that my bite was still perfect from the braces. It was the best thing I ever did!
Hope this helps! The slower they go with braces, and the more conservative they are, the better off you'll be in the long term!
