I'm getting a temporary crown done a week before Christmas at Perfect Teeth, and since I am deathly scared of needles, my mother and I decided to use Nitrous Oxide for the procedure. I'm 24 years old and about 140ish pounds, and I'm breathing deeply into the mask, when I black out. Apparently I had my first Grand Mal seizure and the dentist switches back to oxygen when I come back. I asked my mom what happened and she answered that I had a Grand Mal. So we tried again with the Nitrous Oxide only after a good 10 minutes of oxygen and I blacked out again. This time the Dentist was quicker to switch back to oxygen and woke back up from the second Grand Mal seizure. Even though I'm on a lot of medicine to control my seizures, this is so highly unusual.
I'd like to ask, am I ever be able to go back to using Nitrous Oxide or will I have to face my fear of needles?
