Antibiotics in dental practice are primarily used for two main purposes: (1) treatment of acute orofacial infections, and (2) prophylaxis to prevent systemic complications in high-risk individuals undergoing invasive dental procedures. For treatment, antibiotics are appropriate when there is clear evidence of bacterial infection that presents with systemic involvement—such as fever, malaise, or lymphadenopathy—or when local control via dental intervention (e.g., drainage, extraction) cannot be achieved immediately. Conditions warranting antibiotic therapy include dental abscesses, cellulitis, acute necrotizing ulcerative gingivitis, and severe periodontitis with systemic symptoms[1]. However, the majority of dental infections can be effectively managed with procedural interventions alone, without antibiotics[1]. Prophylactic use of antibiotics is most clearly indicated for patients at the highest risk of infective endocarditis—such as those with certain cardiac conditions—who are under
