The purpose of this study /survey was to determine the knowledge about gummy smile and its treatment options among dental students. A harmonic smile should show the whole extension of incisors, canines and pre molars and has a slight touch of those teeth on the lower and upper lip curvature. Excessive gingival display may make the smile displeasing or even repulsive. Nowadays, gummy smile correction is becoming a prime treatment objective in response to patient demand. The gummy smile is diagnosed when there is 3 mm or more gingival tissue in smile. The etiologies that plays role in the gummy smile are often multifactorial, like extrusion of the upperanterior teeth, upper alveolar protrusion, short clinical crown, short lip, altered passive eruption and vertical maxillary excess. Treatment options are surgical, orthodontics, Botox lasers and various other options are available. A link of a questionnaire comprising 25 questions were sent among 110 students. Students who participated in survey were asked about a gummy smile, causes of gummy smile, normal lip length ,forms of periodontium, botox its mechanism ,methods of injecting Botox ,side effects about surgical treatment and orthodontic treatment. Data was collected through google forms. The study results suggests a synergistic relationship between various treatment modalities of gummy smile. The decision of the treatment method lies purely in the hands of a clinician. Patients expectation, expenditure, and esthetic sense also play a vital role. This survey presents that the participants have good knowledge about the factors associated with gummy smile .84.5% of people were aware that short clinical crowns may be a cause of gummy smile in patients whose gingiva is absolutely normal. 71.8% of people also correctly answered that high smile line was seen in gummy smile patients. Improvisation is needed in the field of BOTOX for treating gummy smile as it can be the most promising method in the near future.  Conclusions: In a nutshell we arrived to the point that dental students who are majorly undergraduates have fair knowledge about gummy smile, and it’s etiology, but they lacked knowledge on diagnosing factors such as length of upper lip, it’s length as age advances, basic forms of periodontium that needs to be assessed for gummy smile.
