In my case it was the endodontic( root canal specialist) denist that found my bad teeth. If you need a root canal, insist they pull it. At this point, I wonder if I'm going to make it out alive. My eye is badly infected, the skin is really inflammed. My family thinks I'm nuts, my friends are sick of hearing about it, my husband isn't sexually interested(can't say that I blame him), I look like something out of the night of the living dead. Better to have missing teeth and a life, than teeth and illness.
