I have had what felt like uncontrollable chattering teeth during vibrations (they hadn't reached my head yet). I had been getting tension headaches and noticed that I had a lot of constant tension in my jaw, so I started focusing on releasing that tension every night before bed and finding the cause of the tension so I can release the need for it altogether. I haven't had any problems since. I also noticed I was very tense and on edge in general the particular day I had that experience. And during the actual experience the chattering stopped after I focused on relaxing my forehead and ignoring the teeth. Hope that helps you with your situation in some way.
