Hey Dental Students. I'm a medical student and I usually post in other forums. However, I need to ask someone "in the know" a question about teeth. I recently got a root canal, and I've been sitting on a temporary filling. My dentist wants me to get a "crown" over the root canal as a permanent measure, but I really just want another permanent filling (the original fell out). (And I don't have the "crown" type money....) Do you HAVE to get a crown when you get a root canal? I've experienced no pain with the temporary filling, and that seemed to be my dentist's main argument.
