That's very unfortunate, sorry you've had to go through this inconvenience. I will preface by saying that photos are always helpful. Anyhow there should not be yellow stains around the borders of your veneers. Possible reasons are the type of cement that was used and its shade (color). Another possible reason could be that a glycerin gel was not used during the cementation process. This prevents an oxygen-inhibited layer that could form between resin cement and porcelain, which could result in chalkiness or discoloration. Another reason could be that the underlying shade/color of your teeth (dentin) is showing too much through the veneer. Either the porcelain is extremely thin in that area or too transparent. In reference to your right side and left side looking too uneven, it is always paramount to have a pre-treatment diagnostic waxup prototype of the end result, which is used as a guide throughout the process. This always allows the dentist to duplicate the prototype on your teeth before treatment and also while your temporary veneers are on. This way you and the dentist can both be interactive, analyze and be critical of any discrepancies or subtleties that you don't like, before the final veneers are made. My suggestion is to find a cosmetic dentist who has had extensive educational background and training with such facilities as Spear, Kois, and/or Dawson Academy. They thoroughly train dentists on diagnosing, planning and executing beautiful, predictable, and long-lasting cosmetic dentistry. I would also recommend a dentist who uses premier dental laboratories who produce strong, quality, yet beautiful porcelain veneers and crowns. There are thousands of labs in the country, but there are only a select few that consistently produce exceptional results. We fall under those two categories, and would be happy to help. Otherwise, best of luck!
