Doctors tend to be totally overcautious about medications in breastmilk. If you take a Tylenol you have to pump and dump for a week- just kidding of course but you get my drift. Believe Infant Risk if you're going to believe anyone- and have your DH call IR if he doesn't believe you. You are definitely going to want to take the painkiller. I had 2 wisdom teeth out and it was a miserable experience.
Did you talk to anyone about just going with local anasthesia?
