Poor fitting crown

[stephenry]

Looking for some advice:
In 2013 I had a root-canal and a porcelain crown fitted. In doing so, I ran into a number of problems:
1) On the first attempt for the crown-fitting, the crown wouldn't fit. In fact, it was a very poor fit.
2) Paid for a second crown, poor fit; it was attached.
3) Approximately 3 months later, the crown split.
4) Return to original dentist, who replaced crown with porcelain on mental (to be stronger, apparently). Again, didn't fit. (cost covered by the dentist).
5) Had another crown made (cost covered by the dentist), again very poor fit. Dentist spend around 1hr grinding the crown down and attached it (when the next patient arrived).
6) Today, around three months later the crown remains high and has begun to give me some trouble. Strangely it can be somewhat painful despite having had a root canal.
I am considering having the crown replaced by my new dentist. I don't like the prospect of having to pay for the crown again and feel that the original dentist is at fault for my situation. I cannot go on however with the discomfort that I'm in at the moment.
What advice would you give me in this situation?

Wow

Most dentists today still use a tradtional impression technique that will occasionally lend to a problem of fit.
It isn't unusual for a dentist to have to spend a bit of time to "fit" the crown. However it shouldn't take a very long time and when the doctor is finished it should fit the edges pretty well, have no gaps between the teeth allowing food to pack in, and the bite should fine fine. This is the basic crown that everyone should expect.
It is not rare to have to remake a crown when the above conditions aren't acheived. This is routinely done without any additional costs to the patient.
I don't know where you are from but in the USA if your dentist is a member of the ADA then they typically have a patient complaint board that you can complain to. The dentists on the board are volunteers and they are typically more than fair to the patient. This is the easiest way to get your money back if the original is not willing to go along with a requested refund for money spent on the defective crown.

For those of us that enjoy digital "impression" technology we usually have much less adjustments.
