I had a root canal done 3 days ago and i am in agony around my sinuses. It was a upper molar 3rd from the back. During the procedure i did feel alot of pressure around my nose and under my eyes. Has this happened to anyone else? How long did it last for?

Turns out an infection in my tooth has spread to my sinuses when I had the root canal done. Has anyone else had that happen to them?

Have been given Augmentin has anyone had this drug before? Any awful side effects?

Many years ago, I had a root canal on an upper tooth - the dentist punctured my sinus cavity, and P.S. I had to have an operation after all that. I never went back to him again. Did you have your root canal done by a specialist? That was my problem. I should have gone to a specialist in the first place.

It was just a general dentist. The antibiotics are not clearing anything. How did you know he had punctured the sinus cavity?
