I came to the office to remove a lower left jaw tooth. Prior to this visit I had experienced a great deal of pain in my right shoulder. This had occurred for several years. It bothered me to the extent that I found it nearly impossible to bring my right arm back over my shoulder. The lower jaw tooth (#19) had a root canal performed up t 15 years earlier. Upon the removal of my lower jaw tooth the pain diminished by a good 70%. It still feels almost pain free 2 months later.
