Quick answer
Porcelain veneers commonly last 10–15 years or more with good care; composite (resin) veneers usually last about 5–7 years. How long yours last depends mostly on the material, the quality of the bonding and your habits — grinding, biting hard objects and skipping cleanings shorten their life. Dr. Mendoza backs his porcelain work with a 20-year written warranty.
Lifespan by material
| Material | Typical lifespan | Main weakness |
|---|---|---|
| Porcelain / E-max | 10–15+ years | Can chip under heavy force |
| Composite resin | About 5–7 years | Stains and wears faster |
What makes veneers fail early
- Grinding or clenching at night — the most common cause of chipped veneers.
- Using teeth as tools: opening packages, biting nails, pens or ice.
- Gum disease or decay at the edge of the veneer.
- Poor preparation or bonding, which is why the dentist and lab matter more than the price.
How to make them last
- Brush twice a day with a non-abrasive toothpaste and floss daily.
- Keep professional cleanings every six months.
- Wear a night guard if you grind your teeth.
- Don't bite directly into very hard foods with your front teeth — cut them instead.
- Limit staining drinks if you have composite veneers; porcelain resists stains far better.
Can I eat normally with veneers?
Yes. Once they are bonded you can eat normally. Common sense applies with very hard or very sticky foods, just as with natural teeth.
What happens when a veneer wears out?
It is replaced. Your natural tooth stays underneath, so a new veneer can be made. That is also why a long warranty matters: it shifts the cost of an early failure from you to the clinic. About the 20-year warranty.

Do veneers last forever?+
No dental restoration lasts forever, but porcelain veneers commonly last 10–15+ years, and many last longer with good care.
Do veneers get bad breath or stain?+
Porcelain itself resists stains and odors; plaque at the gum line can cause both, so hygiene matters as with natural teeth.
