I'm (probably) going to need a tooth out and my dentist said it'd be done under sedation. What worries me is that I've had sedation before for an endoscopy and it seemed to do bugger all. I was entirely aware of what was going on, felt all the gagging/choking and was completely compos mentis when I was wheeled back to the waiting room - my dh even commented that it didn't look like I'd had anything at all.
The only effect it had was I fell asleep a couple of hours later for an hour or so.
I am terrified of having this tooth out, it would be a complicated extraction and I really really would prefer not to know anything about it! I'm worried that the sedation won't work and I'll be aware of what's happening.
