Girls went today for a tooth checkup, I'm 37 weeks and 5 days pregnant. They found pulpitis, did an X-ray with a protective apron, prescribed medication and said if it hurts too much to take painkillers, what can be taken by pregnant women? Can someone tell me about this situation during pregnancy? Thank you in advance.
