what happens if i take oxycontin before surgery?

i had some oxycontin tonight for a pain disorder. and tomorrow morning i have surgery to get my wisdom teeth pulled. i see that some people undergo rapid detoxification of opiates under general anesthesia but isnt that dagerous as well. i just want to make sure i wont have any complications during surgery.
