Karis, I am just now finding your message on the board. I am really sorry for all the trouble and pain your poor husband has had to endure. If it were me, I would be calling around to find a more professional dentist/ oral surgeon. Your husband has been put thru hte wringer and is still haging out to dry ( in a manner of words). I have been thru my share of dentist and pain. It seems to me, once the xrays were taken, why was your husband given the false hope of trying to save this tooth (root canal etc) instead of them just saying, it woud be best to extract it. Why was this "crack" not noticed to begin with? Now, he is on antibiotics for infection and he is swollen and in pain.......... Maybe you need a lawyer......I wish you and your husband all the luck in the world. Keep us posted!
