Does anyone know if you automatically have to crown a route canal, or does it depend on the situation?

If the tooth is a posterior tooth such as a molar or premolar it will absolutely need a crown. When you take the nerve out of the tooth, it loses its blood supply and then can become brittle. Think of a dead tree branch. The force placed on your posterior teeth is very great and the chances of you breaking that brittle tooth are much greater. If the root canal is in a front tooth, some dentists say you might not need a crown. I'm not as convinced about that method though. A dead tooth turns dark, I've had one in the front. You may be able to get a veneer for a front tooth, but I feel a crown would be a stronger restoration. If you spent the money saving the tooth with a root canal, why risk a fracture to that tooth that may cause you to have to have the tooth extracted?
