Objective: This cross-sectional study evaluates YouTube Shorts’ recommendations on teeth whitening to determine the prevalence of various treatments and the engagement levels of this content. Method: A sample of 75 videos were analysed based on speaker type (e.g. dentist, blogger, dental product company), recommended treatment, viewer engagement, and claims regarding efficacy. Results: While bloggers and product companies accumulated larger view counts, dental professionals, particularly dentists, provided more thorough discussions of treatment safety and efficacy, using tools such as shade guides and discussing potential sensitivity issues. Conclusion: These findings underscore the influential role that social media content creators play in shaping public perception of cosmetic dental treatments, as well as the pressing need for evidence-based, professional material online.
