Hello! I didn't have laughing gas, but they did give me 2 pills that I had to take 45 minutes and then 30 minutes before they pulled my teeth. It did give me a relaxed, I don't care feeling. I was nervous about taking them, but I did fine. I think it was something like a Valium. I just don't understand why your dentist doesn't want to do it. You have lots of trouble and your family has a history of bad teeth. My denturist told me that he hated to give me dentures because I was so young(33), but he knew that I had so much trouble with my teeth. It also runs in my family. Good luck!
