The short answer: 10 to 20 years
Well-made porcelain veneers, correctly indicated and properly cared for, last between 10 and 20 years. Composite veneers have a shorter usable life, typically 5 to 7 years.
Those are not marketing numbers. They are what we see in our own follow-ups: at AM Estética Dental we have documented cases still in the mouth after more than 13 years, and we photograph them precisely because longevity is the part nobody can fake.
What actually wears them down
Three things shorten the life of a veneer more than anything else. The first is bruxism: if you clench or grind at night and do not wear a guard, you are applying forces the ceramic was never designed to absorb.
The second is using your teeth as tools — opening packaging, biting nails, chewing ice. Ceramic is extremely resistant to compression but vulnerable to sharp impact.
The third, and the one people underestimate, is the gum. A veneer is only as stable as the tissue around it. Neglected gum health eventually shows at the margin, no matter how good the ceramic is.
What does NOT wear them down
Coffee, wine and tea do not stain properly glazed porcelain the way they stain natural enamel or composite. That is one of the real advantages of ceramic over resin.
Normal chewing does not wear them either. Neither does regular brushing — in fact, routine hygiene is what protects the margins where veneer meets tooth.
How to make them last at the top of the range
Wear a night guard if you have any history of clenching. Keep your six-monthly check-ups so we can see the margins before a problem becomes visible. Avoid biting hard objects. And keep your hygiene routine boring and consistent.
Patients who do these four things reliably land in the 15 to 20 year range. Patients who ignore the night guard are the ones who come back early.
When it is time to replace them
The usual signs are a visible line at the gum margin, a small chip at an incisal edge, or a change in how the bite feels. None of these are emergencies, but they are worth assessing.
Replacing a veneer is a planned procedure, not a rescue. When a case is well documented from the start, the replacement is straightforward because we know exactly what was done and why.
