Are non-prep veneers any good?

Hello there,When considering veneers, I usually recommend minimal prep veneers, over non-prep veneers and here's why:Zero prep veneers sound great to the patient, but in my 12 years of experience as a cosmetic dentist, I have found that no prep veneers are not nearly as reliable as minimal prep veneers.  For example, if you sometimes grind your teeth, chew abrasive foods (steak, candy apples, hard candy, nuts, etc.) you will find that zero prep veneers are much more likely to break or fall off, no matter the dentist that does them.  This is so common, that the overwhelming majority of dentist will never guarantee these veneers will last longer than a year.  This is simply because the dentist does not want to endure the cost of replacing and redoing the veneers.       Conversely, minimal prep porcelain veneers (EMax or Empress, depending on your case) have much great durability.  So much so, that when they are done right by a dentist that knows what s/he is doing, you can expect to get 20 years or more out of them.  In the case of porcelain veneers, we usually offer a 10 year warranty against the veneers falling off or breaking.        Whichever dentist you choose, just make sure that they have plenty of before and after pictures of their actual patients, so you will know that they know what they're doing and what you can expect.  Good luck and I hope this helps.

I assume autocorrect changed your question to Duration.... But yes, if Durathins are appropriate for you (don't know without exam, xrays, photos, etc) the result can be fantastic.  Many dentists are unfamiliar with the material, so the fact you are asking means you likely found someone that knows how to do this and uses a lab that is fantastic.Understand, however, that it should be considered irreversible.  If you don't like them, removal will not result in "prisitine virgin teeth", but the affects of removal may be insignificant enough that you don't care.

I agree with my dental colleagues that if you are happy with your teeth, whitening and replacing the buccal composites - what you yourself suggested is an excellent option. 
All veneers require a thought out plan for both occlusion (to make sure they do not chip off or break) and for appearance. The decision between veneer types really depends on the amount of change you are looking to achieve. In a given scenario almost any product can be the most suitable - that is why they are all in the market. 
Usually though the minimal intervention that makes you happy is the best solution. 

Good luck with whatever you decide to do -
