My crowned tooth #19, which had a previous root canal
, unknown number of years ago, developed an absess at the bottom of the roots.
During my 2nd visit, while Endo doc was removing the previous old post to gain access to the abscess, he told me he caused a small perforation in the root. After an hour and a half, he finished the treatment...and filled the tooth. I'm on Penicillin. Doc told me to expect some discomfort and called last night to check on me. Good Doc. And, complications happen!
