Not sure how different wisdom tooth extraction is, but I got one of my molars removed in February, after having problems with it for a couple of years since a root canal a decade ago.
It wasn’t terrible, but I wouldn’t put it that high on my list of pleasurable experiences either. No real pain (due to the anaesthetic), but the feeling of the dentist applying all his strength to crack my tooth and wrench it from my jawbone was quite… disconcerting.
I think he also messed up the injection too and caused a bit of nerve damage that lasted a couple of weeks (felt something like a sharp electric shock during one of the injections, which I’ve never experienced before, and the left side of my tongue was numb for a few days after).
It also bled quite a lot for the next few hours. I should probably have gone home immediately to rest but went to buy some electronic components instead, then realised in the store that blood was dripping down my beard and face (couldn’t feel it because of the anaesthetic). Fortunately I was wearing a dark face mask at the time, but it was a bit grim.
Overall, 3/5. I’ve also been recommended to get some of my wisdom teeth removed, but I’m not in a rush.
