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?

Actually, he kept saying there was 'no bleeding, which is good to see'. He even explained to me when I asked about that little kink out the bottom of the longest root that the kink would act as a plug to prevent anything entering back up into the canal! I was not encouraged at that explanation since my two previous root canals had nothing extending down past the end of the tooth canal showing on the z-rays following the procedures.

Will the permanent filling be applied over the gutta percha, or will he try to pull the percha and insert steel pins? The root canal was done down through a gold crown which is pretty much being left in place.
