           changed or replaced the entire outer surfaces of
           the anterior teeth with bonded composite resins.
           This changed the way teeth looked when the
           patient smiles. Although the results were dramat-
           ic, many times the bonded material for full smile
           makeovers did not withstand the test of time.
           Often, the bonded surfaces would break or wear
           down. Other times, they would absorb stains lead-
           ing to discoloration. (figure 28)

                   A stronger and more permanent material
           had to be developed; hence the porcelain veneer
           was created. Porcelain veneers are very thin
           pieces of porcelain (they can be made as thin as a
           contact lens), which fit directly over the outside
           existing teeth. (figure 29). They are permanently
           fused to existing tooth structure with a liquefied
           bonding adhesive which is cured by a special cur-
           ing light. (figure 30).

                  In order to avoid creating teeth that look too
           bulky, (caused by layering too much material on
           top of the teeth), a small amount of tooth struc-
           ture must be removed. Doing so makes the final
           result look and feel more natural.

                 There is much publicity about drill less thin
           veneers today. However, experience shows that
           this application has limitations. Most patients
           requiring porcelain veneers need some tooth
           reduction to obtain a natural and realistic result.

                 When teeth do not have enough natural tooth
           structure to support a porcelain veneer, a crown
           must be fabricated. The entire tooth surface must

                                                                                    25
