I assume there are different types of Tourette's with different causes and different treatments, but it was really amazing to see this link to the jaw.
I have no medical background at all, but I wonder if this could be related to the dopamine hypothesis of Tourette's. [1]
Bruxism and other mandibular issues can be associated with dopamine dysfunction. Normally I wouldn't think that the jaw could actually cause the problems, but perhaps there could be some kind of feedback loop there tied to dopamine.
