Was scrolling through the comments to see if anyone mentioned this. I started taking magnesium supplements a couple of years ago after hearing somewhere (forget where at this point) that it helped with teeth grinding. Whenever I'd go into dentist appointments, they'd always mention something about my teeth grinding and recommended getting a mouth guard, which I didn't pursue due to expense. Oddly enough, they never mentioned magnesium. When I started taking magnesium supplements every day, my grinding almost completely stopped. I now notice after a couple days if I haven't taken it, my jaw starts tensing up again and naturally reverts into clenching mode. I don't have any medical expertise or evidence to back its effectiveness, but it sure worked for me. Worth a try before exploring other options.
I second this. I've had bruxism as long as I can remember, which mostly manifested as really loud popping and pain when I opened my mouth wide. I tried some random magnesium supplement for a while and noticed no change, then years later I did some deeper research on the type and dosage and landed on Doctor's Best High Absorption Magnesium Glycinate Lysinate [0]. After a couple nights, the pain and popping completely disappeared. It's the biggest pharmacological effect I've ever experienced.
Note: If you get this brand, notice that the dosage is 2 pills/night.
