Dental veneers are thin shells made of porcelain or composite materials that are custom-made to fit over the front surface of a tooth. They are used to improve the appearance of teeth that are discolored, chipped, misshapen, or have gaps between them. Veneers can also be used to improve the appearance of teeth that are slightly crooked or have uneven surfaces. The process of getting veneers typically involves two to three visits to the dentist, during which the teeth are prepared, impressions are taken, and the veneers are fabricated and then bonded to the teeth. With proper care, dental veneers can last for many years and provide a natural-looking and long-lasting solution for improving the appearance of teeth.
