Porcelain veneers are fabricated in a dental laboratory from high-strength ceramic — they are more lifelike, more durable (lasting 10–20+ years), and the premium option for comprehensive smile transformations. Composite veneers are applied chairside from resin in a single appointment — they cost less, require no preparation time, and are fully reversible, but typically need replacement or maintenance after 5–7 years. Both can produce beautiful results; the right choice depends on your budget, timeline, and goals.
