I have been using neurontin after a fall (5yrs ago) which left me with extreme back, neck and head pain. I really couldn't stand the way it made me feel because they also had me on Motrin, as well a host of other pain relievers, did some epidural & lumbar injections, etc. So I took it less frequently than was origibally prescribed. I have been noticing that my teeth often hurt and they definitely have been moving. Causes severe headaches and face pain. My bite is now off. Recently, I've been getting awful headaches compounded by a strong car sick/dizziness that lasts for days. My teeth, although no visible damage such as cavities, discolorization, are extremely sensitive and have moved so much that I often bite the sides of my mouth, etc. I've heard recently that neurontin sometimes cause mouth/teeth pain and such. Is it possible that this was all caused by the neurontin, and how do I correct it. Is it too late or will not taking it at all reverse the damage?
