The first set fabricated had dark triangles and gapping.My dentist sent them off to another lab. I though the new lab would be re making them but I found out that he is only having her try to fix the old ones! I asked for bl3 and the dentist said bl4 would be better so I took his word for it. In the photo below, you can see the the veneers look more a1 than a bleach shade.What do I do if, upon seeing the veneers Thursday, they are still not what I want? If I allow him to cement them I'm stuck!
