Porcelain veneers are thin shells made of porcelain that are bonded to the front of teeth to improve their appearance. They can address various cosmetic concerns such as discoloration, chips, misalignment, and gaps. The process involves removing a small amount of enamel, taking impressions, and bonding the custom-made veneers to the teeth. Porcelain veneers are durable, stain-resistant, and provide a natural-looking result. However, they may not be suitable for everyone, and a consultation with a dentist is necessary to determine eligibility.
