At timestamp 29:30, Dr. Breiner tells the story of a patient that was a lady that broke her pinky finger.  Her hand surgeon put a metal pin inside her pinky finger.  She developed a terrible infection in her pinky finger.  Her hand surgeon wanted to amputate her pinky finger.  She refused.  She had constant pain in her pinky finger, and she lived with this pain for 12 years.  Dr. Breiner found that she had root canal teeth with dental cavitations.  Dr. Breiner extracted her root canal teeth and did dental cavitations surgery on her.  This woman’s pinky finger pain went away and she has regained mobility in that pinky finger.
