On average, porcelain veneers should last around 10-15 years if cared for correctly. To extend the life of your veneers it is important to practice good oral hygiene habits, avoid chewing on hard objects, address any issues you may have with teeth grinding, and use a mouth guard if playing contact sports. If for any reason your veneers experience damage, contact Dr. Milner right away and he will be happy to assist you.
