I am freaking out! When I get my wisdom teeth pulled will I still be able to sing?

I have to get all 4 wisdom teeth pulled. Tomorrow. I am in 2 plays, both musicals. One is a kid's show that opens in 2 weeks, and one is Sweeney Todd that opens in June. I am freaking out. Am I going to be able to talk and sing for this show I have in 2 weeks? It is a musical. And will I be ok to sing the intense and very difficult Sweeney Todd music by the second week of June?! Is there ANYTHING I can do to make the healing process go faster so that I can sing, act, and project my voice well in 2 weeks for my shows? AHHH!!!! I am so afraid I won't be able to sing! Especially for Sweeney Todd, we start intense and nightly rehearsals tomorrow night and I am afraid of missing too much....
