While that's quite possibly true, I forgot to mention that I'm not in the US but India. I was conscious the whole time, with only local anesthesia. Also the dentist in question is actually our "family" dentist, and he's a pretty knowledgeable/skillful guy (easily more knowledgeable than many GPs on health matters of the body).

Fun fact, you can totally get them to pause the procedure without saying a word. All you have to do is end up in a lot of pain, have your heart rate skyrocket like anything, and get everyone in the OT very concerned ;)
