I was one of the lucky people. I have a really wide mouth so all my wisdom grew in and I never had to get any of them pulled :) it's honestly my biggest fear LOL
When I got all 4 of mine out, I didn't really remember the procedure. I was sedated but if they told me to open wider or something I'd know to do that, so hopefully yours goes smoothly. What I found wayy worse was the soreness the next few days. I was prescribed Tylenol 3 but it didn't do anything so I didnt use it - I found taking advil + regular tylenol together every 5 or so hours helped a lot more but it also made me suuuper drowsy so i was mostly asleep for the next few days.
