@Jacques6 - I always thought that getting sedated would be a good idea for dentist work. I had a bad dental visit as a kid too. The dentist was a little bit of a creep and I had severe bruising in my mouth for weeks after. I was so happy to have the tooth out, I tried to forget about the bad dentist.
Anyhow, I always have my dentist use the laughing gas because I don't know if I like the idea of being unconscious during the operation.
