Apparently it is

I just called the dentist's office and asked them about the night guard situation. Apparently it's not supposed to stop the clenching, just the wear on the teeth from the clenching. And they can't separate the jaw any more because it being unnaturally separated can cause more jaw problems than ever before. So....my symptoms may be slightly diminished but they won't go away....sigh.... what a pain in my neck, literally!
