Had a root canal done on an existing capped tooth, then several months later pain and infection, so surgery took place to clear root above gumline.
Now a year later I'm in pain again. The tooth felt long like something was pushing it down to make it longer.
I went to my Endo, had xray and he said there's No Infection at the root but said my sinus looked stuffy.
Now I feel a cold sensitivity on that upper tooth and it's starting to hurt my lower jaw tooth with a root canal directly under that top tooth that had a root canal.
I'm just out of ideas and want this to stop.
