Veneers are thin shells placed over the front of teeth to improve aesthetics or protect tooth surfaces. There are two main types of materials used: composite and porcelain. Veneers are used to restore chipped or discolored teeth, close gaps, cover worn edges, straighten crooked teeth, or whiten yellow teeth. The procedure involves placing cheek retractors, applying veneers to the tooth surfaces, and finalizing the result. Veneers typically cost between 3000 to 9000 Rs per unit.
