For cosmetic reasons, are veneers or crowns better? About eight of my teeth, top and bottom

Porcelain veneers and porcelain crowns are very similar in appearance (and often made from the exact same material), but a veneer removes less enamel than a crown.  This is a good idea, if possible, in case more work is needed in the future.  If very little tooth structure remains and a crown needs to be replaced, a replacement may not be an option.  If a tooth already has a crown, then a veneer is no longer possible.

Excellent question. 
It depends on the individual situation. Typically, veneers are more conservative and thus you preserve a lot of your own natural tooth structure; however, for individuals who are grinders, and have worn down teeth or an unusual bite/occlusion, crowns would be the better alternative. In most cases though, we can achieve great aesthetics with porcelain veneers. 
The best way to go is to schedule an in-person exam with a cosmetic dentist that is experienced in both crowns and veneers. 
Best of luck!

Hi:Veneers require less of the tooth structure to be shaved down, however there are circumstances that a crown is required for better protection.Best,Dr. Maddahi
