New York dental help needed: I have a back tooth that is hurting me really bad. I feel like someone is jabbing me in the tooth with a hot poker. I had a slight pain in that too for some time but nothing this bad. I would like to see the dentist but worry about the cost. I have some money but what if I need a root canal which leads into needing a crown. I know I do not have money for that type of dental care. Suggestions please.
