I just took laughing gas today at the dentist to fill a tooth that looked like it was beginning to have a cavity. Piece of cake. It took 10 minutes and at the beginning my pulse was high but the laughing gas made me calmer and it felt totally normal. It didn't hurt when I had anything done in my mouth because of it. If your scared, don't be. Easiest 10 minutes ever. The only symptom is dizzyness or wooziness. It may give a headache depending on how high the gas is raised. Good luck!
