Veneers are thin shells that are typically made from porcelain, composite resin, or zirconium. Porcelain is the most commonly used material for veneers since it is highly durable and has a natural-looking appearance that mimics the translucency and sheen of natural teeth. Composite resin veneers are less expensive but not as durable as porcelain, and they may need to be replaced more frequently. Zirconium is a newer material that is stronger than porcelain and can be used for both front and back teeth, but it is less commonly used for veneers. The choice of material for veneers depends on the individual’s needs and the dentist’s recommendation based on factors such as the condition of the teeth, the desired outcome, and the budget.
