Bryanna is tops about this subject. Oh Granny, I do know people who have spent alot to retain their teeth. The RC teeth are not worth a re-do, no matter what your doctors say. These RC teeth have infection in them which eventually do just what yours did, infection under, then you spend more and more on the same teeth. It is a big money making industry and they don't tell you the truth. The tiny cannals inside the tooth, retain infection. They can never get all of it out no matter what proceedure or re-proceedure they do.
If there is any way to swing it, implants may be the best, so you can have a normal bite and look. Bryanna can tell you about each tooth and really what is going on. Don't spend any more money until you get the full scoop OK? I am sorry you are having these issues. ginnie
