Dental appliances not only can treat the misaligned bite, temporomandibular joint syndrome (a cause of severe jaw pain), ear problems, snoring, sleep apnoea, and headaches, but may also help alleviate some symptoms of Parkinson's disease, Tourette's syndrome, and torticollis (twisted neck), and many others.

I do not necessarily agree with bite raising appliances! However, what these videos do show is that the cause lies in TMJ dysfunction, Occlusal, and maxillary misplacement under the cranium. Please read my article on symmetry
