So in 2014, I had a root canal done on my first maxillary molar. Less than three years later, I got an abscess and my dentist told me it was because the root wasn't filled properly. I got an apicoectomy done. Two months later, a fistula appeared and I had to get another apicoectomy. Seven months pass without any trouble but in late January, I got yet another fistula. I was told that this is a chronic abscess and the only option is extraction but I'm only 20 and I really don't want to start losing my teeth this early. Is this really my only solution?
