However, the resultant smile may be too uniform andit is preferable to exhibit a rise and fall in the soft tissue byhaving the gingival contour over the laterals located towardthe incisal compared to the tissue level of the centrals andcanines [Figure 10]. The gingival margin of the lateral incisoris 0.5–2.0 mm below that of the central incisors. The leastdesirable gingival placement over the laterals is for it to beapical to that of the centrals and or the canines.
