What the numbers say
Long-term studies report survival rates above 90 percent at 10 years for bonded porcelain veneers. Failures cluster in patients who grind, bite hard objects, or skip maintenance, not in the material itself.
What shortens veneer life
Nighttime grinding is the biggest enemy, followed by biting ice, pens, and fingernails, and using front teeth as tools. Gum recession can also expose the veneer margin over time, creating an aesthetic line even when the veneer is intact.
How to protect them
Wear the nightguard, every night. Keep six-month cleanings so margins stay monitored. Floss daily, since decay at the veneer edge is a leading reason for early replacement. Non-abrasive toothpaste keeps the glaze bright.
Replacement, when the time comes
Replacing veneers is usually straightforward: the old porcelain is removed, the tooth is re-refined, and new veneers are bonded. Modern materials and shade work often make the second set look better than the first.
Key takeaways
- •Expect 10 to 20 years with good habits.
- •A nightguard is mandatory protection.
- •Regular monitoring catches margin problems early.
