OH MY GOSH!!!!! Was your mouth sore and did you have a hard time keeping it open? Well if that is the case your dentist made you have TMJ!!! Does your jaw hurt during the day? Your teeth? Your ear? Your joints? I have TMJ and if your jaw pops and locks like mine you probably most likely have TMJ. If your dentist caused it I feel super bad for you becuase TMJ Hurts bad!!!!!! I have it!!!! And it is not covered by any way with dental insurance! You should go back to his office and ask him to check if you have TMJ and if you do, you need to do something!! I am 110% serious! Splints can cost up to 8,000$ if you get tens units and all that! Do something!
