Really interested any out there can help me understand having jaw or teeth pain..I understand how it can happen as we have sympthetic nerves through our closed circuit system.. My dentist has actually picked up on a "halo" or "shadow" ring around the root of my tooth, unexplainable and it hurts all of the time.. root canal done in the nerve of the tooth.. so pain has to be in my jaw at the base of the tooth.....Any thoughts???
