Veneers are custom-made porcelain laminates that are placed over the tooth and bonded directly to it for a permanent transformation. A cosmetic dentist can use dental bridges (false teeth) attached to a porcelain crown on each side. The porcelain crowns are bonded into place, creating a fixed bridge and a complete smile. Sometimes, patients have teeth that appear to be uneven because of an uneven gum line. Gum lifts can be performed to lift and reshape the gums.
