Question:
Dr Sam, what is the life expectancy of porcelain venners? My doctor claims that unless I get the best quality I may have to replace them after 5 or 10 years.
Answer:
The two most important factors that determine how long porcelain veneers last are the bonding technique used by the dentist and the skill level of the dentist. There are many different dental bonding kits by each manufacturer and there are many different manufacturers and there are many combinations of materials in the kits. Additionally there are over 7 generations of dental bonding materials kits that have been developed that add even more confusion as dentists try to keep up with the new products.
Unfortunately, most of the new products were designed to save the dentist time and sacrificed bonding strength. The newest products are actually weaker than the first generation bonding materials. The dentist finds that his or her porcelain veneers do not last because they don’t know that the material they are using is weak.
The technique used by the dentist has to be meticulously perfect. Dental bonding is either perfect or it fails. In my dental office, we see more and more patients that just had porcelain veneers placed that keep falling off. These patient are frustrated and angry. Their dentist may not have good enough technique skills and/or may be using inferior dental bonding materials. After successfully bonding porcelain veneers for over 25 years, my oldest porcelain veneer case lasted 26 years before the patient passed away. Not one porcelain veneer broke off or chipped during the 25 years. My best advice is to pick the experienced dentist, because they are worth it.
