You'll be somewhat sore for a few days depending on the periodontal condition of the teeth. You should feel better each day after the extractions.
Here is what you do. Wake up in the morning and see how you feel. If you feel good, go to work. If you feel bad, stay home. I couldn't stop the bleeding and I didn't want to be spitting blood out at work all day, so I stayed home. And no it doesn't hurt. It's tender near the extraction sites and you won't be eating steak for a while, but it doesn't really hurt. They gave me some drugs for pain and I didn't need to take any of them.
