Still had pain, was sent to another endontist, for second opinion, who could not be conclusive, but thought pain
was coming from molar behind the tooth with root canal
which has the crown
seated temporarily. Endodontist did root canal on the second tooth, behind root canal done first. That tooth was sensitive to cold but that has stopped since root canal a week ago. I am still having pain in the molar that had the first root canal. I am on a 4th round of antiboitics.
