For patients who may be embarrassed to smile or laugh because of chipped, stained or misaligned teeth, porcelain veneers are an excellent solution to getting their dazzling and amazing smile back. Porcelain veneers are very thin shells of porcelain that are placed on the teeth, which will result in the teeth looking aesthetically pleasing and natural looking.
The porcelain veneer fabrication process starts with the preparation of a patient's affected tooth. Following this, an impression of the prepared tooth is taken. Thereafter, through the use of ceramics and a mixture of different powders with a liquid, the veneer preparation is fired in an oven to mimic the patient's natural tooth. Then, provided that the dentist is satisfied with the end product, the veneer is placed on the patient's tooth.
The lifespan of porcelain veneers is one that has been subjected to change in recent times. According to the classic research study performed by Friedman 10 years ago, it indicated or suggested that dental veneers can have a lifespan of at least 15 years. However, the result of that study has now been questioned since dentists have found that dental veneers placed on more tooth structure and enamel seem to last much longer than ones placed or 'veneered' on less tooth structure.
Veneers placed on less tooth structure have been found to have a life expectancy that is hard to predict. The lifespan of such veneers has been found to depend on various factors. Patients' habits like teeth grinding, oral hygiene practices and various other factors have been found to lead dental veneers to failure much before their time. However, in general, dental veneers are regarded by dentists as one of the more predictable procedures in dentistry, having the capability to last a very long time, while offering aesthetic benefits to patients.
