Gary Brecka runs the Ultimate Human Podcast.  In this video, he tells the story of his friend from Atlanta.  This man from Atlanta had blood work showing an autoimmune disease.  He also had terrible back pain.  Gary asked him, does he have root canals or tooth extractions?  The man said he had 4 root canal teeth and 4 wisdom teeth extractions.  He also had bridges and caps.  Gary told this man to go see Dentist Dr. Jigar Gandhi in New York.  Dr. Gandhi did dental cavitations surgery on this Atlanta man.  About 48 hours after this procedure, Gary called this Atlanta man to find out how the procedure went.  The Atlanta man said his back pain was gone.
