Do my temporary veneers look crooked? (photos)

It is really not possible to evaluate your temporary just by looking at the photos provided. There might be some other factor in having them functioning which would only be determined by actual examination. You should see your dentist and share your concern with him/her prior to fabricating your final restorations.

Hi:It’s best to voice your concerns to your dentist before the final veneers are fabricated.  Many times temporaries are flawed but the finals are much better.Best,Dr. Maddahi

The temporaries are too too long for you and at the gum line they are too "fat." Teeth, especially womens teeth, are more slender at the gum line and taper out. In order to properly detemrine the length of teeth, you need to actually take a phot of yourself with your lips completely relaxed and parted. Try saying "emma" in the mirror - you should see 1-2mm of teeth.  
 Also, one of the temporary veneers has a hole in it - this is because it was too thin. Therfore, your permanent veneer will be thicker than the temporary and will look bulky. 
Best,

Once there is a hole in the veneer, it usually needs to be redone. Even if anything could be added, it would need to be done in a lab and it can be difficult to remove the veneer to send back to the lab without destroying it.

Hello and thank you for your question. Keep in mind, it will take some time to get used to the look of your veneers, but I do see the area of your concern. However, I recommend following up with your Dentist about your concerns or consult with a Prosthodontist, who can discuss with you the different types of veneers to give you the best long-term results. A Prosthodontist is a dental specialist who has advanced training in restoring teeth and can create a customized treatment using the latest techniques in dental veneers.
