Take my argument with a grain of salt. I'm not an expert. But, if nothing helped you. I can give you my experience.
What really helped me. I went from grinding a lot to almost nothing. Was, I fixed my teeth. My front teeth was a bit worn out from acid drinking and food taking. Though, they looked quite normal. My problem was that my teeth where porous. Acid always slipped into to the pores, which cause my teeths to hurt(more like itching, think like a small scratch whom). Not even brushing my teeths or washing them with listerin helped, because the acid slipped very deep into the pores. Dentists couldn't see from any xray scan what was wrong, so they refused to give me any treatment that would remove some parts of the teeth. It took me a lot of effort to convince a dentist to get me something that almost resembles a teeth crown(it was more like a filling). After getting these teeth crowns, me and my wife have not noticed any teeth grinding since.
I'm beginning to suspect whether bruxism is caused by the body's reflex to tooth ache? Note, I have amateur researched this topic a lot and I don't quite bought the argument of stress, but I was pretty convinced about the argument of the body's reaction to insufficient oxygen. But, I didn't quite bought this argument either. Because, if we worn out our teeth, it would be naturally deselected by Darwin's law a long time ago. Since, we would have a small deficiency of chewing. And it would be strange if only humans did tooth grinding and not other animals? But, what we humans have been doing a bit more recently is having an increased acid consumption, which lead to my argument if bruxism is just a reflex to tooth ache?
Note, there are treatment like (epoxy??) that can fill the pores, though it didn't helped with my ache. Once, the tooth ache was gone, so was my teeth grinding.
