Dentist found a crack in this
tooth. Went to endodontist who did root canal in Feb.,
pain continued, endodontist went back into tooth deeper. 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.
