What damage is caused by dentist sanding veneers?

Hello there,It sorry to hear that you're unhappy with your veneers.  I would recommend having them redone if you do not like the way your veneers look.  Consult a cosmetic dentist to determine your options, and always look at before and after photos when selecting your dentist. They will give you a good idea about what you can expect. Good luck and I hope this helps. Follow me if you have more questions.Sarah Thompson, DMDSt. Louis, MO area (O'Fallon, IL)Real Self 100

A well crafted porcelain veneer, created by talented lab technicians, are layered with different colors of porcelain.  Some labs will save time and money by staining the porcelain to give it character, but this usually does not last, as time goes by the stain can come off.  It is possible that your dentist used a lab that stained the porcelain, and by polishing the stain off the veneers appeared a little whiter.  "Slight" is the best one could hope for, significant change is impossible.However, polishing porcelain after this treatment usually is not as smooth as they were when the lab created them, and likely never will again.  It is very difficult to polish in the mouth.  It is less significant when only a spot or two are polished, but when entire surfaces get "sanded" then the challenges are greater.  Also, the surface texture/anatomy is usually removed, leaving a very smooth surface, which is unlike real teeth that have "ripples" and variation in texture.
