I never mentioned that I finally got a Night Guard.  I had bought one from the drugstore a while back, but it was incredibly uncomfortable and made things worse.  So one day in January, B and I went in to see his dad for our first dental check-up in two years, and his dad kindly took a mold for me.  Two weeks later I had my own, custom-fitted night guard.  It fits over the top teeth, and it keeps my teeth separated at night.  If I grind, I grind my teeth on the cushy plastic (instead of wearing my own teeth down).
It was a little difficult to get used to at first.  It made me super-aware of how I normally clench my jaw, and indentations immediately formed in the plastic.  At first I had to consciously force my lower jaw to relax and slide back a little bit.  But B hasn't heard any grinding since I started wearing it, and there is less pain.  Over time I have even stopped clenching so much, and I don't have to pop my jaw in the morning.  I've even forgotten to put it in a night or two, and I felt my jaw slacken on its own. It's kind of an incredible feeling!
When I was taking voice lessons, this jaw lock was a major problem for me.  I had to practice singing with a pencil between my teeth to force my jaw to relax.  I wonder if I could do it a little better on my own now.
So in essence, praise the Night Guard!  (Thanks, Dr. S, if you're reading this.)  I may look like a 13-yr-old, putting my "retainer" in every night, but I don't even care.  I feel *SO* much better, so the fact that it's unattractive or that it makes me lisp a little bit couldn't matter less.
