Porcelain veneers
Veneers were originally invented by a Californian dentist to temporarily change the appearance of actors' teeth. But, because they were affixed by denture adhesive, which at that time was not as well developed as nowadays, they tended to fall off within a short time. Therefore, their use in private dentistry was not widespread.
Today, with improved cements and bonding agents, veneers typically last anywhere from 10-30 years, depending on the lifestyle and oral hygiene of the patient. They may have to be replaced during this time. The cost of veneers can vary depending on the dentist's experience and where you have the work done. Porcelain veneers are said to be somewhat more durable and less likely to stain than veneers made of composite material.
