I experienced this after a dose increase of Gabapentin. My Dr immediately lowered me back down to my 300 mg dose. She prescribed Lyrica to help calm down the receptors in my mouth, to let my mouth heal.. I also practice homopathic medicine and I gargled with peroxide for 1 minute, baking soda and water for 3 minutes. I did this 3 times a day until my mouth started to get better. Hope this helps somebody.
