At one time, crowns (caps) were the only alternative to restoring badly discolored or decayed teeth.  More recently, porcelain veneers and composite bonding have become available as an attractive alternative.  Now there’s another alternative to make natural teeth look their brightest.  This process reverses the discoloration of tooth enamel to create a whiter, more aesthetic appearance.  The advantages of this procedure are that no natural tooth structure is lost and in most cases anesthetic is not necessary.
