(1) Objective: This study aimed to investigate how patients' perceptions of their dental aesthetics and their sense of self-esteem are related. (2) Methods: This cross-sectional survey recruited 141 new patients seeking orthodontic treatment. Patients completed a self-administered questionnaire consisting of three parts: the Malaysian Psychosocial Impact of Dental Aesthetics Questionnaire (PIDAQ), Rosenberg Self-esteem Scale (RSES-M), and Aesthetics Component of the Index of Orthodontics Treatment Need (IOTN-AC). Clinical assessment comprised the Dental Health Component of the Index of Orthodontics Treatment Need (IOTN-DHC). Multiple linear regression was performed, with self-esteem as the dependent variable, while the independent variables comprised the domains of PIDAQ; IOTN-AC; IOTN-DHC; and patients' demographics, such as age, gender, and their level of education. (3) Results: The response rate was 96.5% (n = 136 respondents). The multiple linear regression found that, when the other predictors in the model are held constant, Social Impact, Aesthetic Concern, and Dental Self-Confidence are the factors that significantly contributed to explaining the variation in self-esteem, accounting for, 3.9%, 2.3%, and 2.0%, respectively. The entire model explained 23% of the variation in self-esteem. (4) Conclusions: Domains of the psychosocial impact of dental aesthetics act as predictors of self-esteem in orthodontic treatment-seeking patients.
