Treat veneers like natural teeth: brush twice daily with a soft brush and non-abrasive toothpaste, and floss daily, especially at the gumline. Skip whitening toothpaste, which can wear the surface. Avoid biting ice or hard foods with your front teeth, and wear a night guard if you grind. Porcelain veneers last 10 to 15 years or longer; composite veneers last five to seven. Call us if one chips or loosens.
