How long do veneers last?
Well-made porcelain, placed correctly and looked after, commonly lasts 10 to 20 years or more. Composite bonding on the same tooth is a different number, closer to 4 to 8 years.
Three things fail: a chip or debond from impact or grinding, the seal at the gumline edge, or the tooth underneath. The porcelain surface itself rarely wears out.
Often 10 to 20 years
Color holds. Porcelain is highly resistant to stain.
4 to 8 years
Cheaper up front, and it dulls and stains on the way.
What actually fails
The first is a chip or debond: an impact, ice, or grinding without a guard can break porcelain that was otherwise fine.
The second is the edge, right at the gumline, where the porcelain stops and your own tooth starts. Dentists call that edge the margin. If the seal there breaks down, decay gets in underneath, and the veneer has to come off so the tooth can be repaired.
This is why the fit matters more than the shade nobody can see from two feet away.
The third is the gum receding over the years and exposing a line of natural tooth above the porcelain. The veneer is fine. It just stops looking right.
What shortens it
- Grinding at night without a guard. This is the biggest one by a distance, and most people who grind do not know they do.
- Skipping cleanings, which is how that edge goes bad quietly.
- Front teeth used as tools. Bottles, packaging, fingernails.
- A bite that was never addressed. If force wore your natural teeth down, that same force is now working on porcelain.
The part you control
Wear the night guard. Keep the cleanings. That is most of it.
The rest was decided before the veneers went on, in how the case was planned and how carefully those edges were finished. You cannot fix that afterwards, which is the argument for not shopping on price alone.
