During my (not very long) life I had eight teeths removed from my mouth - four because my jawbone is too small, another four wisdom teeth (all eight shiny and healthy, what a waste ...) - so I consider myself experienced on this matter
Usually dentists don't put you to sleep but give you injections and it goes all numb. For the first batch I got six injections, for the wisdom teeth a couple of years later it has been eight injections. Whether they 'hurt' depends on how experienced your dentist is and also on luck (that's what the oral surgeon told me), because you never know the exact location of the nerve.
You wait for some time and after it's gone all numb the dentist checks whether you feel anything, then he starts the procedure. You won't feel anything (to be honest, the whole pushing and pullin isn't to convenient either) because, well ... you have been anesthetised
Very nervous patients may also be put to sleep. The advantage is quite obvious, you will feel nothing, not even the pushing and pulling, and wake up after all is over. Disadvantage (yeah, there is one): as soon as you wake up the pain starts. If you get injections the whole area stays totally numb for at least half an our after you're finished, then it gradually regains feeling and you can start taking painkillers at the point where you think it's necessary. If you have been put to sleep pain starts immediately after you wake up, so think about it twice
