Oral health literacy (OHL) refers to an individual's ability to obtain, understand, evaluate, and utilize oral health information to make informed decisions regarding oral care. Limited oral health literacy is associated with poor oral hygiene practices, increased prevalence of dental diseases, delayed treatment-seeking behavior, and poorer overall health outcomes.

Objective

This study reviews the relationship between oral health literacy and preventive oral health practices and evaluates their collective influence on oral health outcomes.

Methods

A comprehensive review of literature published between 2010 and 2025 was conducted using major databases including PubMed, Scopus, Web of Science, and Google Scholar. Studies investigating oral health literacy, preventive dental behaviors, oral hygiene practices, and oral disease outcomes were analyzed.

Results

Evidence demonstrates a strong association between higher oral health literacy and improved preventive behaviors such as regular tooth brushing, flossing, fluoride use, healthy dietary habits, and routine dental visits. Individuals with low oral health literacy exhibit increased rates of dental caries, periodontal disease, and oral health disparities.

Conclusion

Enhancing oral health literacy is essential for improving preventive oral healthcare behaviors and reducing the global burden of oral diseases. Community-based educational interventions, school programs, digital technologies, and healthcare provider communication strategies can significantly improve oral health literacy levels.
