Following the placement of the gutta percha and the temporary filling, I saw the x-ray and a small portion of the gutta percha seems to have made it beyond the tooth and iscrimped over as if it went out the end of the hollowed root. Is this a problem I should be dealing with when the permanent filling is placed tomorrow? It is a lower tooth (#19 if memory serves). I am having zero pain now with it, since it dried out.
From what you describe, it’s sounds like a perforation. I would ask your doctor about it.
Sometimes a perforation does not cause a problem in the beginning, but causes major problems in the future.
If I were you, just “play dumb”, google some info about perforation and bring it into the doctor.
Although, sometimes roots are quite odd and it could be nothing. Did you have any bleeding during the procedure?
