OMGosh, I’m a Neandertal. Anesthetic to that nerve only blocks the pain to the front teeth in my lower jaw.
I found out when I had a root canal in a lower back tooth. The dentist was not aware why the shots she kept giving me were not effective, and she thought I had “hysterical pain,” which I have never had in my life. So after having that procedure with virtually no anesthetic, I found another dentist who was aware of the anomaly. I stuck with him, duh.
