I had visited a dentist for a root canal. Before he started the treatment I asked for the quote and his assistant gave me the quote of $500 after 350 discount. after second visit my dentist told me that he will put a post on the tooth and it will cost me another $285. The problem here is that I was not told about this charge at my first visit, I am not a dentist and I cannot assume that there are several steps in this treatment. My dentist says that this is the usual treatment and it's not his fault that I didn't know. My argument is that they should have told me the total right in the beginning and not just the root canal price. Is this my fault? Should I go back to him? Please advise.
