Hi about a year and 1/2 ago I had a root canal on #14. I developed a fistula and had an apico 1 1/2 months ago. I 've had a bump at the top of my gumline for the past 3 weeks. I just came from the oral surgeon and he put me on a 3week antibiotic.He will follow up in 3 weeks. He did not do any xray today. I am assuming the apico failed and the antibiotic is only a temporary fix. My question is if in fact the apico failed what are my alternatives? I never had any problems before the root canal( it was done because of a crack in the tooth) I really hate the idea of extraction. Is that my only alternative at this point? Is it to late for an endodontist? I did call before my apico and they told me they didn't perform apico's only root canal.
