Hi Nancy - My son used Magic Mouthwash and it worked well for him as long as (he said) he tried to eat the most in before the numbness went away. After a while it didn't seem to work well so he went to another that worked well that was over-the-counter at Walgreens. Then he went back to the Magic Mouthwash. Everyone is different in their reactions and sometimes you have to try different things to see what works. BUT - whatever you try, you should always check it out with your doctor to make sure he is aware and approves of whatever goes into your body, even vitamins or any other medications.
