The Impact of Orthodontic-Related Social Media Content on Patients’ Willingness to Initiate Treatment: A Systematic Review

Background/Objectives: Nowadays, social media is increasingly utilized in the field of orthodontics for information sharing and promotion, yet its influence on patients’ willingness to initiate orthodontic treatment remains insufficiently defined. This systematic review aims to synthesize the available evidence on the impact of orthodontic-related social media content on patients’ willingness to seek orthodontic treatment. Methods: An extensive literature search was performed across five electronic databases up to August 2025, complemented by manual screening of reference lists. Randomized and non-randomized studies evaluating orthodontic-related social media exposure and reported treatment-related willingness or motivation outcomes were considered for inclusion. Results: A total of 1243 records were identified, and eight studies met the inclusion criteria, including six cross-sectional studies, one randomized controlled trial, and one qualitative study. Given the diversity of study designs and assessment methods, the results were synthesized narratively. Visually oriented orthodontic-related social media posts, particularly outcome-focused imagery such as before–after photographs, were more frequently associated with increased willingness to seek orthodontic treatment compared with technical content. Gender-related differences were reported, with female participants appearing more responsive to orthodontic-related social media exposure. Across the included studies, Instagram was identified as the platform exerting the strongest influence. Conclusions: The findings of this systematic review indicate that visually oriented orthodontic-related social media content, particularly outcome-focused imagery such as before–after photographs, shows more consistent associations with willingness to seek orthodontic treatment, alongside gender-related differences and platform-specific effects.
