@carol1024 I've now had 2 root canals in same tooth and an incision and drainage of the sinus tract into my hard palate. I was told (and have also read) that it's very difficult for antibiotics to treat an infected tooth because of limited blood supply to the area. They have to address the infected tooth or infection won't go away no matter what antibiotics you take. That has absolutely been true in my case.

@carol1024 i didn't even know that was possible. My guess was he just wanted it out and we possible shouldn't have waited on the root canal even with no pain. I shouldn't have had the crown placed without doing the root canal work. That's also on the dentist.
