Went to see the Doctor because of a locked jaw. He worked with me on my TMJ for about 4 sessions and it improved tremendously. The staff as well as Dr. Core were kind and considerate about the pain and discomfort I was feeling throughout the process. Word of warning...pay attention to the handout they give you. It is correct in that I wasn't sure of the device I was going to be wearing but within a few days it was a part of me with no problems just as stated in the document.
