Step-by-step explanation:
The type of indirect restoration that is placed to improve the appearance of the facial surfaces of teeth is commonly known as veneers. They are specifically designed to cover the front surface of teeth to enhance their appearance. These restorations are usually made from porcelain or composite resin materials and are custom-made to fit the shape, size, and color of the individual's teeth. Veneers are an effective solution for a variety of dental concerns, including discolored, worn, chipped, or misaligned teeth. They provide a conservative approach to changing a tooth's color and shape because they do not require extensive shaping prior to the procedure that crowns do, and the process is usually irreversible, making them both a non-destructive and aesthetic choice. Dental professionals utilize adhesive technology to bond the veneer to the tooth structure, providing an improved look and sometimes added strength to the affected teeth.
