The lifespan of cosmetic treatment depends on the procedure, material, bite, oral hygiene, diet, and maintenance. Whitening may need periodic maintenance, bonding may require polishing or repair, and well-planned porcelain veneers can last many years with proper care.
Regular checkups are important because cosmetic work still depends on healthy gums and supporting teeth. Avoiding hard biting habits, managing grinding, and cleaning around restorations helps protect the result.
