Treating Bruxism

Are there any natural remedies out there for treating symptoms of bruxism?

My girlfriend has suffered from bruxism (grinding of teeth in her sleep) and other “muscle spasm” like symptoms in her sleep relating to a Post-Traumatic Stress syndrome.
While she has a mouth plate to protect her teeth, her jaw and neck muscles are constantly strained causing major pain and migranes upon waking.
Are there any natural remedies that could possibly assist us? I was thinking perhaps some sought of msucle relaxant that could be applied locally (ie. to her jaw)?
Any ideas/suggestion would be greatly appreciated.

I know how she feels….

Maybe think about osteopath? They can be helpful.
