Hello, I had what my dentist called a "bad cavity". When he first drilled in and filled it he said I needed a root canal. I wasn't having pain so he then said he would just put a crown on it. Once he put the temporary crown on I was in a ton of pain and when I went in to have the permanent crown placed on he said that I would need a root canal and get fitted for another permanent crown. Should I have to pay for the permanent crown that was never placed on me for the cavity filling? Thanks in advance!
