I was mis-diagnosed with Fibromyalgia and put on Lyrica for seven months. I gained over 75 pounds and it destroyed my teeth. So far, I have had nine root canals, many build ups and I am only half-way finished. To complete the restoration will cost me ANOTHER 25 thousand dollars. I have always had excellent dental care and wore orthodontics in my twenties. Right before I began Lyrica, I visited the dentist, with a clean check up. While I was on Lyrica, I noticed that my enamel was falling off, then my teeth started to break. My dentist told me, "He has never seen anything like this"! Now I need a front tooth implant, caps and all of the rest fixed. I have RSD, so I never should have been on Lyrica. It was an old doctor, that just assumed my symptoms were Fibromyalgia. It wasn't dry-mouth, because I had a huge bottle of water, everywhere I went, while taking Lyrica. Now, I have lost 55 pounds and am trying to dig up the money to finalize my dental restoration. The Endodontist told me, when he started drilling, my teeth were like "empty eggshels". They would just blow-up! So, YES, Lyrica causes terrible dental problems. It almost destroyed me!
