What Happens to Veneers/Lumineers After 10-15 Years?

While nothing lasts forever, the reasons for replacement can vary dramatically.  Most often, the reason is a color upgrade or surface "glossiness" re-do.  Loss of teeth is usually NOT the reason for "failure" 15-20 years later.

Since veneer preparations are very conservative, tooth structure still remains.  THIS can decay if not cared for, which could lead to a re-do of the veneer.

At age 25, I would say to expect to have the smile redone 2-3 times.  People are living longer, so one should expect to replace or maintain their case.

Most of our cases that are 25 years old or older are being done for no other reason than they want "whiter" teeth, but the teeth are otherwise completely healthy...

veneers are the same as natural teeth, if you will take care of them, they will stay life long. Choose good material and VERY GOOD COSMETIC DENTIST.

When a veneer has come near to the end of it's life cycle, it's pretty easy to replace.  Think about when you need new tires on your car.....you simply replace them.   Terrible analogy but basically the veneers are removed carefully.  New impressions are taken and then new veneers are made and bonded on.  The clock starts over now.  Technically there is NO limit to the number of veneers you could get on a tooth.  So don't worry about replacement. 

I have veneers on my teeth for 20 years and they still look great. When they begin to look bad then you have them redone. Remember you will have a beautiful smile for 20 years without the worry of yellow teeth, crooked teeth etc. They are worth the money and if your current teeth were so great you wouldnt be asking the question right?

Patients always ask me if veneers are reversible?  Their teeth are yellow and crooked with gaps, so my answer is why would you want your old teeth back? They usually laugh and say you're right! lol

Conservative veneers cases (like UltraVeneers or Lumineers) - when done properly - should last a very long time.  Also, your teeth are minimally prepped in this type of treatment (usually not even prepped through the enamel), and therefore your teeth remain very strong.  When these cases are done properly, they should last over 10 or 15 years.  As long as you take excellent care of your teeth and health, (and you don't have trauma to a tooth that breaks porcelain), and you wear your night guard if it is prescribed by your dentist, then you should be able to enjoy your beautiful smile for decades.
