Porcelain veneers are one of the most transformative cosmetic dentistry procedures available — but they are also a significant investment. A common question is how long they actually last.
The Research on Veneer Longevity
Clinical studies show that high-quality porcelain veneers have a survival rate of approximately 93-95% at 10 years and 82-90% at 20 years. Many patients have veneers that last 15-20 years or more. The range is wide because longevity depends heavily on patient factors, material quality, and the skill of the dentist placing them.
What Makes Veneers Fail Prematurely
The most common reasons veneers fail before their time include fracturing (often from grinding or clenching), debonding (the veneer separates from the tooth), and chipping. Decay around the edges of veneers can also compromise them. Patients who grind their teeth should always wear a nightguard to protect their veneers. Using teeth as tools — opening packages, biting nails, chewing ice — greatly shortens veneer lifespan.
Maintaining Your Veneers
Veneers require the same diligent home care as natural teeth: twice-daily brushing (with a non-abrasive toothpaste), flossing, and regular professional cleanings. Unlike natural enamel, porcelain cannot be regenerated — so maintaining the health of the underlying tooth is critical. Your dentist will monitor your veneers at each checkup for any early signs of wear or damage.
When Replacement Is Needed
When veneers do eventually need replacement, the process is generally straightforward — particularly since the original preparation has already been done. Modern veneers and bonding techniques may allow for repair in some cases of minor chipping. At Smileworks Dental in Calgary, we can assess whether your existing veneers can be repaired or whether replacement is the better option. Book a cosmetic consultation to discuss your situation.
