Smile (disambiguation)

Characteristics and social function

Smiles vary by form and meaning. Some are reflexive responses to happiness, others serve to communicate reassurance, de-escalate conflict, or signal cooperation. The production of a smile involves facial muscles studied in basic facial anatomy, and observers across many cultures use smiles to infer emotion, intent, or social status.
