Hopefully a moderator can pin this thread, and we can all share what treatments have worked for them.
I'll start:
The herb Rhodiola rosea along with buspar are the only things that stopped my bruxism. Rhodiola possibly because of it's MAO inhibition. Be warned though, people build tolerance to rhodiola rosea quickly, so it just might be a stepping stone to buspar. But when i was on it, it forgot I even had a jaw! It was that calm.
I built tolerance, and now I'm on the drug buspar. 10 MG 2 x daily. It made my TMJ worse for a bit, but after 2 weeks, my jaw felt so calm I didn't even believe it.
Also taking calcium and magnesium seems to help.
I found a personal correlation between dry mouth and bruxism... especially if you're taking drugs that cause dry mouth. There's things like biotene that lubricate your mouth
Then, Biofeedback:
