The phenomenon of minimal or absent teeth visibility during a smile is characterized by the upper teeth remaining largely concealed behind the upper lip when a person expresses happiness or amusement. Factors contributing to this can include the individual’s facial structure, the size and positioning of the teeth, and the muscular activity of the lips during smiling. For instance, a person with a long upper lip or shorter upper incisors may exhibit less tooth display when smiling.
A smile significantly impacts perceived attractiveness, confidence, and approachability. The degree to which teeth are visible during a smile can influence these perceptions. Historically, dental aesthetics have emphasized a certain level of tooth exposure as ideal, though contemporary views recognize a broader range of smile aesthetics as acceptable and attractive. Variations in tooth display are considered normal, and preferences often differ across cultures and individual tastes.
