Porcelain veneers typically last between 10 to 15 years on average, though with proper care, some can last up to 20 years or more. The lifespan of veneers depends on factors like the patient’s oral hygiene, diet, and lifestyle habits, including smoking or teeth grinding, which can accelerate wear. How can I extend the lifespan of my veneers? Maintaining excellent oral hygiene, avoiding hard or sticky foods, wearing a nightguard if you grind your teeth, and attending regular dental check-ups can help prolong veneer life. What are signs that my veneers may need replacement? Signs include discoloration, chips, cracks, or the veneer loosening. Regular dental exams can help detect these issues early to keep your smile looking its best. Can porcelain veneers stain over time? While highly resistant to staining, porcelain veneers can still discolor slightly due to exposure to dark-colored foods or drinks.
