Is a root canal necessary before a dental crown is placed? No cavities, dental pulp is exposed.

I cannot say for sure what caused the pulp to be exposed but if there is significant pain, a hole in your tooth, and a pulp exposure then there is no way to get rid of the sensitivity without doing a root canal and build up on that tooth. Trust me you do not want to touch your anterior crowns after they have been finally cemented.

If your pulp is exposed, some pulp protection methods can be tried, but permanent gluing of the zirconia coating is not recommended without making sure that the pain is gone. If this method does not work, you should definitely have a root canal treatment.
