I recently finished a popular dental alignment program, where you have to wear aligner trays in your mouth for 22 hours a day. It solved my clenching problem, but I’m not sure why. I suspect it’s because the aligners created a Small gap between my bottom and top teeth, which is making it very hard to clench now. With the aligners on, clenching became very uncomfortable too because you feel like you’re going to snap the damn things.

Probably a bit of a stretch to pursue dental aligners to fix your bruxism, but hey!
