Botox.. hmm. Interesting.

I chipped / broke half of a crowded-out front tooth one night a month or so ago. My teeth sometimes chatter on their own at night.

My jaw is compact and massively internally-hypertrophic (reinforced) from a lifetime of bruxism. Also, masseters are jacked, teeth roots are extremely long, and my neck muscles are hypertrophic (no neck) too. I wonder if this is an evolutionary adaptation of a "fighter" body plan.
