Me too!!!!!!! I have to have two root canals redone and there is a cavity under one of the crowns too. If I chew I have to have the teeth left. Why do they have to hurt so bad and require so much money. Yes they act like we are all rich. I do not have dental insurance at all. The root canals were done by a different dentist that should not have even been doing them. I wonder if we could sue for poor work? I wouldn't but I am tempted. I have never sued anyone for anything but it sure comes to mind now. One root canal was overfilled and one the root was not even taken completely out and it was underfilled. Its been sore for all time. He kept saying they usually are tender for a long time. You can't believe anything any more when it comes to Dentist. I unfortunately have an appt. this month with a special dr. who deals with root connels all the time. Maybe he can help.
