Health literacy represents a critical determinant of oral health outcomes in the United States, influencing individuals' capacity to access, understand, and apply health information to maintain optimal dental health. This research examines the relationship between health literacy levels and oral hygiene practices, routine dental care utilization, and treatment-seeking behaviors among the general U.S. population. Through a comprehensive analysis of existing literature and empirical data, this study demonstrates that higher health literacy correlates significantly with improved oral hygiene behaviors, increased preventive dental care utilization, and earlier intervention for dental problems. The findings reveal that approximately 36% of U.S. adults possess limited health literacy skills, which directly impacts their ability to comprehend dental care instructions, navigate the healthcare system, and make informed decisions about oral health. This research underscores the necessity for public health interventions that enhance health literacy as a mechanism for improving population-level oral health outcomes. The study provides evidence-based recommendations for healthcare providers, policymakers, and public health professionals to develop targeted educational programs and communication strategies that accommodate varying literacy levels across the general population.
