Dental veneers are thin, custom-made shell or facing that are designed to cover the front surface of teeth to improve their appearance. They are typically made of porcelain or composite resin and are used to correct a variety of cosmetic dental issues such as discoloration, chips, gaps, and misalignments. Porcelain veneers are applied to the tooth’s surface with a special dental adhesive and are often used as an alternative to dental crowns or orthodontic treatment.
