Taking Percocet in third trimester?

..I have a wisdom tooth coming in and it has caused me unbearable pain. I went to the dentist, hoping to just have it removed and it be over with but they want me to take Amoxicillin before they do the procedure. The dentist also wrote me a prescription for Percocet (oxycodone-acetaminophen 5-325) because I had told her that Tylenol alone wasn't helping the pain. I am usually not the one to complain, or take medication unless I absolutely have to. Just wondering if anyone knows the risk of taking this in my 3rd trimester (32 weeks prego) or what it could do my baby. And yes, I know if the doctor didn't think it was safe they wouldn't have wrote it. Not looking for rude or unnecessary comments, just want to know if anyone had good/bad experiences with this medication. (basically looking for peace-of-mind). Thanks in advance.
