Hi...I have severe TMJ . When I first got it my jaw would lock up and I literally would have to put my head between my legs for gravity to open my mouth. I could not get any dental work done for two years because my mouth would not open far enough. Then the joints deteriorated and I can now open my mouth but you can hear a crunching sound when I eat and sometimes when I talk.
I had severe headaches, eye pain, cheek and temple pain and sickening pain in the hard palate behind my teeth. Sore thoats, nose pain, ear aches. I have chewed holes and ridges in my cheeks from bruxism...grinding my teeth in my so called sleep. I got a very expensive mouth guard /splint but it made me choke and was so tight I got canker sores. I have run to the dentist with aching teeth and they could find nothing wrong with them . That's my experience with TMJ. I wish you luck in getting some help.
