My TMJ acts up every time I have to go to the dentist. I had the same result using magnesium! Pain just melted away! I think this is the solution when the problem is more of a spastic muscle situation around the TMJ area. Magnesium is a natural muscle relaxant. I take 300-600mg of CHELATED magnesium 2-3 times per day when my TMJD acts up. I also take Epsom Salt baths which give additional relief.
