Tourettes is caused by molar teeth.
Verbal tics are caused by the upper first molar pinching the Glossopharyngeal nerve.
Body tics are caused by the lower second molar pinching the Phrenic nerve.
Inflammation of the sockets causes clenching and grinding.
Which then cause twitching and vocalizations.
I freakin found it! I tweaked the upper molar a little, and have not spontaneously talked for over a week now. A symptom I have had for 38 years...
I need to make up some diagrams and modulate the vicious rant that is running through my head.
Will write more soon.
