I have heard constant, frequent tapping and other manipulation of a single tooth can damage the Trigeminal nerve. I suspect this may be what happened to me. I went to the dentist with no pain at all and after a lot of excessive work, ended up with a lot of pain in the area. My pain is usually a constant boring pain from my jaw into my ear. It is sometimes, but rarely sharp. Just constant and maddening. Sadly, for me, the pain did not stop, although I suspect that very recently after three years it is a teeny tiny bit better. I think for some people, it does get better and even goes away or practically goes away. My neurologist was able to help me. I had to try a lot of different medications before finding something that helps. My diagnosis originally was atypical Trigeminal neuralgia, but I think it's been changed slightly. Very generally speaking, the two meds that seem to help the most for this pain are Gabapentin and a Tricyclic medication like Elavil, often together. But, everyone is different. And you likely need a good evaluation by a dentist AND a neurologist. Again, many people get better in time, it just might take a long while. After three years I definitely still require medication and still react badly to triggers (very cold weather, very windy weather, vibrations...like car travel, etc.) but, I am grateful to have more control of this monster. With a good doctor, good medications and time, I think there is light at the end of the tunnel. I use a compounded cream, which is different than most folks...you can look at my old posts or pm me for more details. Good luck and good thoughts for swift improvement.
