I have been on Neurontin for over a year for neuropathy and the other day I was looking at me gums and freaked out. My teeth, in the front, lower looked rotten. I have a little gum problem and therefore brush two or three times a day and use a water peek with peroxide every morning. I guess I was focusing too much on the gums to notice my teeth. I know it does a number on your saliva production but I never realized how much. Wow. Went to Target today and got a dentist scaler and pick set and have scraped off the worst of it. Can"t wait for my next cleaning!!!FYI Marsh
