Dental veneers are one of the most popular cosmetic dentistry solutions for enhancing the appearance of your smile. These thin, custom-made shells are bonded to the front of your teeth to improve their shape, size, color, or alignment. If you’re considering veneers, you might be wondering: how long do dental veneers actually last? The lifespan of dental veneers depends on several factors. With excellent care, some patients have maintained their porcelain veneers for 20 years or more.
