My last molar on top was filled years ago. A few weeks ago it broke and was painful. I went to the dentist and they put a crown on it yesterday. Now it hurts even worse. I'm frustrated to say the least. The dentist told me if it was still painful after the crown was on I'd need a root canal. I know I could just have it pulled but are there any other alternatives? It doesn't hurt when I eat but when I drink cold or cool liquids it hurts a lot and flossing it was excruciating. Thanks.
