Dental Crown doesn't fit - twice! Should I go to another dentist?!

Dental Crown doesn't fit - twice! Should I go to another dentist?

I'm in the process of having a crwon put on one of my molars. The dentist has made two impressions and had two crowns come back from the lab that don't fit. She didn't take another impression today, saying that the fault is and has been the labs, not hers, and she's not spending more time/money taking another impression. I'm a little disturbed by this. I have had one crown done by her before that is good. Does this sound like it might be the fault of the dentist taking the impression, or is it really the lab?

Just to clarify, she's going to try and finish the crown, but she wants the lab to make another one off of the last impression. There is no temporary crown (the tooth was a root canal, if this make a difference). Thank You!

She said, this time at least, it was 'short on the buckle' and long on something else...

If the dentist doesn't seat a crown - that is the dentist you DO want to go to. It is very, very frustrating when a crown doesn't seat for both the patient and the dentist. Each time that a dentist has to take an impression, it costs the dentist about $50 - not to mention the lab bill.
If the dentist doesn't seat the crown, it's because he cares more about your oral health more than money. This dentist sounds like a great dentist to me.

but then again... i didn't pass wreb
