Factors that Determine How Your Smile Looks

Incisal Edge                         With all these colors, shapes, sizes and
 figure 22                     arrangements, there is still another part of teeth
                    MILD       that must be considered by both patient and
                     MODERATE  cosmetic dentist. The biting edges of the anterior
                    HEAVY      teeth have a different property of enamel than the
 figure 23                     rest of the tooth structure. This is called the incisal
                               edge. (figure 22)
 figure 24
                                     At the incisal edge, the enamel is usually
                               more translucent than the thin enamel covering
                               the rest of the body of the tooth. This allows light
                               to easily pass through it giving the edge a differ-
                               ent look. When viewed from the front of a
                               person, this appears as a tiny blue-grayish line at
                               the very edges of the teeth.

                                     This blue grayish look is caused by the back-
                               drop and shadowing of the deepest part of the
                               mouth showing through the translucent enamel. It
                               should be decided with the cosmetic dentist if a
                               mild, moderate or heavy incisal edge look is
                               preferred on the incisor teeth. (figure 23)

                                     Another important fact to be aware of is
                               how cosmetic dentists measure teeth. They measure
                               tooth size in millimeters, not inches. Don’t refer to
                               the customary inch scale when asking to have teeth
                               lengthened, widened or changed. Millimeters may
                               be very tiny, but adding just a millimeter can have
                               a dramatic visual effect upon teeth and smiles.
