Dr. Siegert tried to pull my tooth and ended up shoving the root into my sinuses. I then Had to drive to an oral surgon with nothing but bloody cotton in my mouth and half dazed. He said that it has happened to many dentist, but I don't think that's true. It was a horrifying experience and I will never go back. Oh and I should also mention the two root canals I had that he did got infected and so did the one he did for my aunt.
