Final answer:
A veneer is a cosmetic dental procedure used to improve the appearance of the teeth, especially when they are abraded, eroded, or discolored. It is applied to the facial surface of the tooth and is made to match the tooth's natural color.
Step-by-step explanation:
A veneer is a thin layer of tooth-colored material that is placed on the facial surface of a prepared tooth. Its primary use is for improving the appearance of teeth that are abraded, eroded, or discolored. A veneer is not used for filling cavities, treating gum disease, or repairing broken dental instruments.
The structure of a tooth includes the outer surface, known as the crown, which is protected by enamel. This enamel, despite being the hardest material in the body, can still be susceptible to decay and erosion. When the natural look of the teeth is compromised, veneers can be an aesthetic solution.
Dentists use veneers as a cosmetic dental procedure to enhance the visual appeal and provide a protective cover to the teeth. These are bonded to the prepared surface of the teeth, creating a beautiful, natural-looking smile.
