I got 2 on my left side taken out cuz one was impacted, and then like 5 years later I got the remaining 2 on my right side taken out cuz 1 had a cavity and they were like "fuck it" >_>
The impacted surgery was a bitch and I couldn't eat solids for 3 days and had immense pain. But the non-impacted surgery was so smooth. I had no pain and was able to eat in a day and a half.
