What prescription medication might I be given if I'm getting a tooth pulled and a temp bridge?

None usually. If you have heart valve disease or joint replacement a discussion is warranted;otherwise i'd not recommend meds.
Pain meds/antibiotic. Pain medication - to control post-op pain and an antibiotic and possibly an antibacterial rinse.
Pain meds/antibiotic. Pain medication - ranging from non-narcotic to a narcotic and possibly an antibiotic and possibly an antibacterial rinse.
