This practical clinical guide reviews current recommendations for antibiotics, analgesics, contraindications, and prescribing precautions based on guidelines from the American Academy of Pediatric Dentistry and the American Dental Association.

✅ Introduction
Odontogenic infections are among the most common causes of pain and emergency visits in pediatric dentistry. Appropriate pharmacologic management must balance therapeutic efficacy with patient safety. Injudicious antibiotic prescribing contributes to antimicrobial resistance, adverse drug reactions, and microbiome disruption.
Children differ substantially from adults in drug metabolism, organ maturation, and dosing requirements. Consequently, all medications should be prescribed according to body weight (mg/kg) and adjusted to the child’s clinical status.
The core principle in pediatric dental infections is that operative treatment is the primary therapy, while medications serve as adjunctive measures.
