It seems that since I've been taking Lyrica it seems that my teeth have been "demineralizing" of sorts. Starting with enamel chipping and flaking off in medium sizes, then larger pieces and the inside 'pulp' of my teeth has become spongy. I have had pain with this on top of the pain caused by my Fibromyalgia and my Chronic Post-Herpetic Neuralgia.
If you know of any other patients that have had this same problem -- I am 50 years old, I've been on Lyrica now for over 6 months. I have had PHN since 2000 and was diagnosed with FM less than a year ago, although my doctors and I could trace my symptoms back more than 7 years.
