I am finished with Tray 12 today and have a little bit to update. After Tray 11, the attachment on my bottom left tooth was removed and another was placed on my right tooth. I don't know if it is because my right tooth hasn't been moved before, but Tray 12 was so painful: more so than any other previous tray. The bottom tray was really tight when I first put it on and very difficult to remove, which was new for me since it had always been pretty easy to take off compared to the top tray. That first day with it was terrible. I had to eat food that didn't involve any chewing and I avoided eating all together because it hurt so bad to brush my teeth. But after a few days it did stop hurting and I'm hoping my next tray won't hurt as much. And hey, at least I know my teeth are moving! I can't wait to get to the 15th tray when my left front tooth will start to straighten out. I will also have attachments moved around then as well, but that isn't for a few more weeks so I will update then. Here are the usual pics!
