About

Gummy smile is a condition that promotes a disharmonious smile, altering confidence and decreasing self-esteem of many patients. Luckily, this problem in most cases is easily solved by aesthetic crown lengthening surgery. However, this is a surgery that is still considered by many patients to be painful and uncomfortable. Thereby, this study seeks both to evaluate possible changes in patients' self-esteem and self-confidence after the aesthetic crown lengthening surgery.
