I've learned that the TMJ (temporal mandibular joint) is 1/16th from the brain, causes vertigo, blurred vision, migraine-some types, and so many things, oh choking, hoarseness, neck and shoulder pain.
Much is caused by head forward posture (ears not centered over shoulders if looking at the patient from the side).
Anyhow, I've had incredible improvement with easy to do things such as where the tongue is supposed to be placed in mouth when not eating.
I'm soooooo mad at my dentists - so many out there haven't a clue - they do crowns, re-alignment and on and on and the bottom line is teeth are not supposed to touch (except when chewing in the back molars) so all that changing of bite is a rip off for TMJ, that is.
