Once the correct shape is selected, the focus
should shift to how the teeth line up on a straight
line (the horizontal plane), as viewed from the
front of the patient. (figure 20). Remember, this
horizontal plane should be parallel to the inter-
pupilary line that connects the center of both
eyes. Many variations can be noticed at the edges
of the teeth, as relates to this line. The edges of
the maxillary teeth (the incisal edges) may line up
on a straight line, or they may be arranged so that
the maxillary lateral incisors are shorter to varying
degrees than the central incisors. Staggered
incisal edges make a smile appear more natural
and more youthful. Incisal edges on a flat plane
make the edges look more worn. Worn edges are
more commonly found in patients who grind their
teeth or older patients as they wear down their
teeth over time.

Color is another important consideration.
There are dozens of tooth colors available.
Generally speaking, it should be discussed with
the cosmetic dentist whether a white smile look or
a “natural” look is preferred. Teeth naturally are
not very white, but have more cream-like or light
yellow overtones. The specific colors of individual
teeth can be chosen from general ranges on den-
tal shade guides. A cosmetic dentist can provide
many shade guides from which to choose. (figure
21). For a more natural look, different color
shades may be used within the same arch.
Canines are naturally darker than incisors or pos-
terior teeth
