I haven't had my teeth removed, but I did have 7 teeth removed at the same time. That wasn't that painful for me. They gave me an IV anesthetic and I didn't feel any pain at all when I woke up. However, I did have a lot of bleeding and having all the gauze in my mouth was uncomfortable to me. It might be different for you.

Anyway, as soon as I got home I took a nap and by the time I woke up, I felt almost fine. The bleeding stopped so I didn't need the gauze in my mouth. I started to eat soup and I was able to chew the 'chunks' that were in there. It wasn't until a few days later I was able to actually eat anything completely solid, like waffles or chicken or anything.

I think you should be able to go to your friend's house tomorrow. Again, I didn't get my wisdom teeth removed, but having 7 teeth removed at the same time is close to that.
