I suffer from TMJ as well. My jaw will lock closed on me after any kind of dental work were I have to keep my jaw open for long periods of time.

Have you ever thought about trying a mouth guard? I know when I get to stressed I'll clinch my teeth a lot, which will make my jaw hurt even more. I seem to always have headaches and ear pain on the side that my jaw pops out of socket.

Let me know if a mouth guard helps any. I think you can buy them at places like Wal-Mart now.

Take Care,
Lisa
