<<Disclaimer: Verify this information before applying it to your situation.>> Dear List: I am one of those celiacs who register no anesthesia effect from Novocaine. In anticipation of major dentistry, and unwilling to cause the terrible pain of our last mutual ordeal, my very competent and conscientious dentist researched the alternatives, and found: Carbocaine, and Mepivicaine. In the past (before diagnosis) I have also had trigger point injections with litocaine. I would very much like to know if there is any negative experience to be reported re these local anesthetics. TIA. I will gladly summarize. Nancy in nyc
