Our Lab Direct™ Teeth Whitening Process can lighten teeth which have porcelain veneers. Our Lab Direct™ Teeth Whitening Process will not make a color change in the dental work you have already had done but can remove discoloration from staining. This includes restorations such as: white fillings, bonding, crowns, and bridges. In most cases, a person’s teeth should undergo our Lab Direct™ Teeth Whitening Process first and then afterwards their dental work done to match the new shade of their teeth.
