I'm scared that my temporaries don't look good, what do you think? (Photos)

The short answer is that the temps don't look that great to me.  The longer answer is that I do not know how your teeth looked prior to having Lumineers removed and the temps placed.  My recommendation would be to have the dentist try in the actual veneers before you agree to accept them.  The dentist can place the veneers, then show you how they look, prior to cementing them in.  This would be your best best.   I hope this helps.  Click save under my name below if you have more questions in the future.

Hi:My suggestion is to have your dentist adjust the temporaries to your liking and send a mold of the adjusted temps to the lab.  This way you are going to be more assured that the final veneers will be to your liking.  Otherwise, make sure you inspect the new veneers on your teeth prior to cementation.Best,Dr. Maddahi

It's hard to compare your temporaries to your previous veneers but remember, you are doing all this for an improvement of your smile, just make sure you get to see your new veneers with TRY IN veneer paste before they cement them so yo know what you are getting.As the dentist, we do have some limitations on the outcome but there can be things that we can adjust or modify.  Looking at your photos I would have HIGHLY recommended Invisalign prior to any cosmetic restorations as this could improve the position of your teeth.  If you are concerned with tooth size, you are limited with veneers. Ceramic crowns like eMax would be a better option as you have more control of proportions with full coverage.  Good luck with the new smile!
