Facial aesthetics is shaped not only by genetic predispositions but also by the cultural norms and values.

The positioning of teeth is of significant importance, both in terms of function and aesthetics. Aesthetics is a subjective matter, and there is often a discrepancy between the perceptions of patients and those of medical professionals. The act of wearing a mask has been demonstrated to impair the ability to evaluate facial attractiveness, thereby reaffirming the visual importance of the oral cavity in the context of facial aesthetics. The notion that a face perceived as beautiful is inherently exceptional is a fallacy. An average face is defined as one that exhibits characteristics that are common to the group. However, cultural mutations occur at a faster rate than genetic mutations. With regard to changes in facial aesthetics, cultural differences have a more immediate effect than genetic mutations. The advent of the internet meme may herald the advent of an era in which the average face that defines a beautiful face is determined by the internet.
