How long should veneers last?
With good care, veneers commonly last around 10 to 15 years, and porcelain generally outlasts composite resin, though habits and bite matter a lot.
A common range for well-cared-for veneers is roughly 10 to 15 years. Some last longer. Some fail sooner. Porcelain generally holds up better than composite resin, which tends to need more polishing, repair and earlier replacement. The material is only part of the story. Your bite, habits and home care decide a lot.
What the research shows
Clinical studies of porcelain veneers have generally reported high survival rates over the medium and long term when patients are well selected and the bonding is done carefully. Failure rates were higher in studies where bites were unfavorable, too much tooth structure had been lost, or veneers were bonded mostly to dentin rather than enamel.
Why veneers fail
- Chipping or cracking, often from biting hard objects or grinding.
- Loosening or debonding, which is more likely when the bond is mostly to dentin rather than enamel.
- Decay at the edges or under the veneer. The natural tooth can still get cavities.
- Gum changes that expose the edge of the veneer.
- Staining or loss of polish, more common with composite.
What helps them last
- Brushing twice a day with a soft brush and nonabrasive fluoride toothpaste.
- Cleaning between the teeth every day.
- Regular checkups and cleanings.
- Not using teeth as tools, and avoiding ice, pens and fingernails.
- A mouthguard for contact sports, and a custom guard if you grind.
Veneers are not a one-time purchase for life. Because traditional veneers involve removing enamel, those teeth will need some kind of coverage going forward. Plan for maintenance and eventual replacement as part of the decision, not a surprise later. A small chip in composite can often be repaired in the chair. A cracked porcelain veneer usually needs to be remade. Either way, problems found early at a checkup tend to be simpler to fix than problems found late.
At your consultation
Ask what lifespan is realistic for your bite and the material proposed, what the most common reasons for failure are in cases like yours and how repairs are handled. Ask whether you grind or clench. No dentist can guarantee a number of years, but a good plan can stack the odds in your favor.
