Taml, Thank you for sharing your experience after a root canal. My situation is very similar. I had a root canal 8 months ago on upper tooth number 14 . The night of the procedure my left nostril closed up completely and the next day tons of fluid , blackish blood came out of nostril. My left nostril has been blocked for months with agonizing pain on left side of nose and upper left cheek. I have pain also in my neck left side with tingling.

I have been on numerous antibiotics along with tons of steroid sprays and prednisone.

After months of being told my dental x ray and my cone beam scans are clean finally one oral surgeon pointed out I had gutta percha that was.overfilled in to my sinus and various parts of my gum. This meant that my sinus lining was punctured. I saw the Endodontist and dentist who did the root canal and crown who never mentioned the overfill in my sinus.

This has been a nightmare due to to agonizing pain I have in my left nostril and upper right cheek . It feels as if my nose and upper left cheek are broken.

All the dental providers tell me the tooth is fine and that the overfill has shrunk a little so they are refusing to pull the tooth. They claim they don’t see an infection and that to pull the tooth will cause even more damage since it sits under my sinus. They say I have little bone and to remove will be a huge problem.

I’m so depressed and in so much pain. I actually feel suicidal at times due to my pain . I found every medical provider dismissive since my scans are not showing an infection just the gutta percha that they claim should not be causing this degree of pain. Thank you very much for sharing your story.
