Received a permanent crown today due to large amount of decay in top right back molar. I am taking 600 Mg of ibuprofen and still having tremendous pain that is throbbing and feels like pressure. My dentist said to continue the ibuprofen and add acetaminophen, but this is giving me no relief. What can I do? Oh and it is a porcelain crown, and an emergency dentist is out of the question due to cost and travel time.
