Porcelain Veneers | YouTube

This post was written by Dr. Mahmoud H. Al-Johani

Veneers were invented by a California dentist named Charles Pincus. At the time, they fell off in a very short time as they were held on by denture adhesive. They were, however, useful for temporarily changing the appearance of actors’ teeth.

Research started in 1982 by Simonsen and Calamia revealed that porcelain could be etched with hydrofluoric acid, and bond strengths could be achieved between composite resins and porcelain that were predicted to be able to hold porcelain veneers on to the surface of a tooth permanently. This was confirmed by Calamia in an article describing a technique for fabrication, and placement of Etched Bonded Porcelain Veneers using a refractory model technique and Horn describing a platinum foil technique for veneer fabrication. Additional articles have proven the long-term reliability of this technique.

Today, with improved cements and bonding agents, they typically last 10-30 years. They may have to be replaced in this time due to cracking, leaking, chipping, discoloration, decay, shrinkage of the gum line and damage from injury or tooth grinding. The cost of veneers can vary depending on the experience and location of the dentist. In the US, costs range anywhere from $1000 a tooth upwards to $3000 a tooth as of 2011. Porcelain veneers are more durable and less likely to stain than veneers made of composite.
