Objectives: (1) To evaluate the influence of the amount of gingival display on smile esthetics and to compare the esthetic perception of six levels of gingival exposure (−3, −1, 0, +1, +3, +5 mm) between orthodontists, maxillofacial surgeons, dental students, and laypersons. (2) To evaluate the most acceptable level of gingival display during smile. Materials and Methods: Twelve adult females (20–30 years of age) were included in the study. A frontal intraoral and a frontal extraoral smile photograph were obtained from each of them. A total of six images were created with different levels of gingival display. Each image was evaluated for its attractiveness by 60 observers. Results: Analysis of variance with post hoc Tukey's correction was the statistics used. The average ratings for gingival display of −3 and +3 mm did not differ across all the observers. Dental students and laypersons gave significantly higher ratings for −1 mm and 0 mm and significantly lesser ratings for +1 mm and +5 mm, when compared to the orthodontists and maxillofacial surgeons. Conclusions: The smile with 0 mm gingival display was considered to be the most esthetic by all observers. Smile with +1 mm gingival display was the second most attractive smile according to the orthodontists and maxillofacial surgeons while for the dental students and laypersons, it was the smile with −1 mm gingival display.
