New porcelain veneers falling off (Photo)

Question

I recently had permanent porcelain veneers fitted by a well-reviewed Cosmetic Dentist on Teeth 4-13. Within a few days, the veneers on 3, 14, and 7 all came off. The dentist said this was likely due to the lab not treating the porcelain properly. He has now offered to redo them entirely. I'm looking for a second opinion on whether this sounds right? For a supposed top tire cosmetic dentist, this seems like a massive mistake. I'm concerned. Thanks in advance!

There are many reasons for veneers to come off after placement.
1) poor bond due to improper isolation and treatment of tooth and veneer
2) pool lab prep on inner veneer surface
3) The most common is occlusion or bite disturbance.   You may have just been biting too hard at the junctures of the veneer to tooth and a thorough bite analysis needs to be performed and adjusted once the new veneers are in
4) many more reasons but it would not all fit into this text box.
Good luck

Hello, the work and preparations looks great, i think this is due to the grinding and the wear on the teeth. Looking at how worn down your lower right canine is ( tooth 27) and the worn back teeth i see a lot of grinding and potential airway issue that will cause veneers to continually pop off/ fracture.

There can be many causes for the veneers to fall off such as bleeding gums or poor cementation of the veneers or poor quality of the products. In that case, it is necessary to change all the porcelain veneers.

Hi! Sorry to hear that you are experiencing this. Yes, this could happen if the veneers were not properly prepared (etched) by the lab. Although the etching should be checked prior to cementation, it may not always be obvious by visual check. The other reason may be that you have bite interferences in those areas which weakened the bond when you clench and grind at night. Wearing a properly made protective guard (quick splint or a POD are best at decreasing clenching and grinding forces ) is an important part of protecting your restorations & maintaining your smile.
