Can veneers be placed on existing front teeth crowns?

Hello there,I would not recommend placing veneers over crowns.  If you're unhappy with your crowns, I would suggest seeing a cosmetic dentist who can replace your current crowns with porcelain crowns that will look just as good as veneers. Always look at before and after photos when selecting your dentist.  This will give you a pretty good indication of what you can expect.  Good luck and I hope this helps.

This is not advisable since there is no benefit to leaving the existing crown on the tooth. For the same amount of money, the crown is removed, the underside surface of the tooth is disinfected and a new porcelain crown is placed over the tooth. The new porcelain crown is made from the same material as a veneer so it's it's esentially the same as new veneers.Hank D. Michael, DMD

Unfortunately not. In order to prepare a tooth for a crown, you would have to shave all around and on top of the tooth. Basically your tooth would become a smaller version of itself and the crown would cover it and replace the missing tooth structure. When the existing crown comes off the tooth underneath is ground down all around and needs to be covered again with a new crown. The veneer would only cover a part of the tooth and the rest of the previously cut tooth structure would be exposed.  So you would have to replace a crown with another crown only. 

No, you cannot do veneers once you already had crowns, what you need is new crowns. zirconium would be great choice, metal free great resistance. you can change shape, size and even color. 

While this is possible it is rarely a first choice.  It can be done to repair porcelain on a large bridge.  Usually replacing crowns is first choice.Ira L Shapira DDS, D,ABDSM, D,AAPM, FICCMOThinkBetterLife.com
