Dental veneers are thin shells made of tooth-colored materials, like porcelain or composite resin, that cover the front surface of teeth. They enhance the appearance of teeth by improving aesthetics and addressing issues like discoloration, chips, cracks, gaps, and minor misalignments. Veneers are custom-made and bonded to the teeth using dental adhesive. They are durable, stain-resistant, and provide long-lasting results. However, it's important to note that veneers require a small amount of enamel removal and proper oral care for maintenance.
