Do my temporaries (crowns) have to be the way I want them before the impressions are sent to the lab?

I am having my two front crowns redone and the temporaries are not exactly the way I want my new crowns to look, example, the line down the middle not perfectly centered (stuff like that). Should I have the dentist perfect the temporaries and make a new impression before he sends it to the lab?

The lab will center the midline of the crowns on the midline of your lower, natural incisors. The temporaries are only temporary, but they should be somewhat acceptable in shape and contour--length especially. The fine tuning will be done by the lab--don't worry about that... The temporary impression to the lab will be merely a guide for the final product. The lab will use the basic dimensions of the temporaries to build the new crowns. The intricate details and other anatomic features will be totally independent of the temporaries.





If you are not absolutely, 100% happy with the result at the try-in appointment, do not accept them. Sometimes, you can wear the new crowns with a temporary cement as a trial to see how you like them. Of course, nothing will be perfect and your natural teeth are always the best as far as looks and function. Also remember that natural teeth are not perfect and any attempts to mimic absolute perfection will result in teeth that look fake. Good luck with everything!!
Reply:The temporaries have NOTHING to do with the finished crowns. They are TEMPORARY and will not be perfect.
Reply:They are just temporary. They are there to prevent your other teeth from shifting and so you won't go walking around with drilled down teeth.lol jk Although your temps don't look perfect, the lab will do their best to make them look perfect....also when you go back for cementation and if you do not like they way they look, tell the dentist. You have every right to change the shade. It's your money :-)
