Hollywood Smile enhancements typically endure for 10 to 15 years—or even longer—when maintained with excellent oral hygiene and regular dental check-ups. High-quality materials like porcelain veneers or zirconia crowns are highly durable and resist staining, but factors such as grinding, acidic diets, and neglecting routine care can shorten their lifespan. By brushing twice daily, flossing, and visiting your dentist for periodic cleanings, you can prolong your stunning new smile for well over a decade.
