Porcelain veneers were invented in California by Dr. Charles Pincus. Early porcelain veneers were held on with denture adhesive, which often fell off after a short period of time. Over the years, bonding technology improved greatly, and now porcelain veneers are bonded to your teeth with a sturdy and safe permanent adhesive. On average, porcelain veneers can last anywhere from ten to thirty years before replacement may be required due to tooth grinding, wear, chipping, cracking, etc.
