Wow, I am glad I didn't read this before my dental appointment on Tuesday. I am dental phobic and don't need any more reason to be scared! I had to have eight novacaine shots to get fully numb in my right upper mouth, where I was getting two crowns. Had no reaction whatsoever (other than severe anxiety and sweating until I was fully numb). I've had a lot of dental work over the years and have never had any bad reaction to novacaine. Lucky me.
