Dr. Flynn extracted an infected lower wisdom tooth. After 2 weeks I went back because it still hurt. He examined it and said it was healing properly and that takes a long time. I still had off and on soreness on the side of my neck and a very bad sore throat so that sometimes I could barely swallow. A week later I went to my own dentist to have a crown put on the molar next to the extracted wisdom tooth. He immediately pulled out a sharp bone splinter about 1/8 in. in diameter. It was in my gum next to the molar. I hope that fixes it. No excuse for Dr. Flynn to have left it in there in the first place, and to have not found it when I went back saying it wasn't healing properly.
