Yes: A permanent filling after the root canal is needed. In your case a filling will be placed in the access prepared through the crown. Most likely an amalgam (silver) filling should be placed. At this procedure the root canal openings will be sealed. If it is an older crown, you may want to consider replacing it, as a defective crown margin may have led to the need for canal in the first place.
Dr. Kenneth Grossman

Yes: But it is not called root canal final sealing. That refers to the canals only. And that material is different than the final filling in the access cavity. For a gold crown, i prefer a bonded composite filling to amalgam. I don't like amalgam next to gold. Dissimilar metals can cause some problems. Endodontists are well trained to do fillings also. You will be fine.

Maybe: Since the seal on the crown has been disturbed, you may benefit by having a new crown made on this tooth.
