i had a hole drilled in my bridge to do a root canal in number 19 which apparently was neved finished. i had a check up for another cap issue recently and the dentist i saw now wants to replace this entire bridge which i can not afford in any way. please advise as to any options i have to get this root canal finished and keep my bridge. it is loose now and i must have other work doen so money is a huge issue. thank you
