Incisor creases are V-shaped natural anatomical spaces located above the points where teeth meet. The depth and form of these spaces directly determine the character of a smile; in younger individuals and women, these creases are deeper, rounded, and more prominent, giving the smile a softer, more dynamic, and feminine look. As age progresses, these V-shaped spaces flatten and disappear due to wear and tear on the teeth; in the design of male patients or when a more mature masculine expression is desired, the angles of the creases are planned with steeper, more square-like boundaries. The aesthetic surgeon shapes these tiny anatomical spaces at the micron level, creating an illusion that perfectly matches the patient’s age and gender identity.
