The rational use of antibiotics in pediatric dentistry is essential to prevent antimicrobial resistance, reduce adverse events, and ensure safe, effective care. Current guidelines from the American Academy of Pediatric Dentistry (AAPD) and the American Dental Association (ADA) emphasize that most dental infections in children can be managed without antibiotics when local treatment is possible.

✅ When Antibiotics Are Indicated in Pediatric Dentistry
Antibiotics should only be prescribed when there is systemic involvement, risk of dissemination, or when dental treatment alone is insufficient.
1. Odontogenic Infections With Systemic Symptoms
Antibiotics are indicated when infections present with:
▪️ Fever >38°C
▪️ Facial swelling or cellulitis
▪️ Lymphadenopathy
▪️ Difficulty swallowing (dysphagia) or trismus
▪️ Risk of airway compromise
Common first-line options:
▪️ Amoxicillin
▪️ Amoxicillin–clavulanate (Augmentin®)
▪️ Clindamycin for penicillin-allergic patients

This article reviews updated antibiotic protocols, mechanisms of action, and the most prevalent acute dental infections in children. Emphasis is placed on rational antibiotic use to prevent bacterial resistance and optimize clinical outcomes.2. Acute Facial Cellulitis of Dental Origin
Requires:
▪️ Systemic antibiotics
▪️ Drainage when indicated
▪️ Close clinical follow-up
3. Traumatic Dental Injuries With Pulp Exposure + High Infection Risk
Situations such as:
▪️ Luxation injuries with contamination
▪️ Avulsion of permanent teeth
Recommended:
▪️ Amoxicillin or doxycycline (for children ≥8 years)

Dental Article 🔽 Odontogenic Infections: Impact on General Health and Comprehensive Management ... Odontogenic infections arise from dental pulp or periodontal tissues and represent one of the most common causes of oral-facial emergencies.4. Patients With Specific Medical Conditions
Antibiotic coverage is recommended for:
▪️ Immunocompromised children
▪️ Children with certain cardiac conditions requiring endocarditis prophylaxis following AHA guidelines
Only specific procedures (manipulation of gingival tissue, apical region, or perforation of oral mucosa) warrant prophylaxis.

Management of pulpal infections in primary teeth must follow AAPD evidence-based protocols, prioritizing pulp vitality and infection control.✅ When Antibiotics Are Not Indicated in Pediatric Dentistry
AAPD and ADA emphasize several cases where antibiotics offer no clinical benefit:
1. Localized Dental Infections Without Systemic Involvement
Examples:
▪️ Localized pulpitis
▪️ Localized periapical abscess without fever or swelling
▪️ Periodontal abscess confined to the gingiva
These are best managed with:
▪️ Pulp therapy
▪️ Drainage
▪️ Restorative care
▪️ Analgesics
2. Irreversible Pulpitis or Symptomatic Pulpitis
Antibiotics do not reduce pain or improve outcomes.
📌 Recommended Article :
Dental Article 🔽 Dental Abscesses in Primary Teeth: Evidence-Based Management in 2025 ... Dental abscesses in primary dentition represent one of the most common pediatric dental emergencies. They can lead to severe pain, swelling, and systemic involvement if not treated promptly.3. Routine Dental Procedures
Including:
▪️ Extractions without complications
▪️ Pulpotomies
▪️ Restorations
4. Viral Infections
Herpetic gingivostomatitis and other viral lesions do not respond to antibiotics.
💬 Discussion
The overprescription of antibiotics in children significantly contributes to drug-resistant bacteria, allergic reactions, and gastrointestinal disturbances. Evidence demonstrates that local dental treatment is the most effective therapy for the majority of pediatric infections, while antibiotics serve only as adjunctive therapy in specific systemic conditions.
Adherence to AAPD and ADA guidelines ensures:
▪️ Lower risk of antimicrobial resistance
▪️ Reduced emergency visits
▪️ Improved patient outcomes
Providers must carefully evaluate whether systemic involvement is present before prescribing antibiotics, especially in younger children, where unnecessary exposure increases risks.

Dental Article 🔽 Managing Pediatric Odontogenic Infections: Diagnosis, Symptoms, and Treatment Guidelines ... Odontogenic infections in children are frequent emergencies in pediatric dentistry. They arise from bacterial invasion of dental pulp and surrounding tissues, commonly due to untreated caries or trauma.🔎 Clinical Recommendations
▪️ Prioritize definitive dental treatment (pulp therapy, extraction, incision and drainage) whenever possible.
▪️ Prescribe antibiotics only when systemic involvement or facial cellulitis is present.
▪️ Choose amoxicillin as the first-line agent; use clindamycin for penicillin-allergic patients.
▪️ Avoid antibiotics for pulpitis, localized abscess, or routine procedures.
▪️ Follow weight-based pediatric dosing strictly:
° Amoxicillin: 20–40 mg/kg/day divided every 8 hours
° Amoxicillin–clavulanate: 25–45 mg/kg/day divided every 12 hours
° Clindamycin: 10–25 mg/kg/day divided every 8 hours
▪️ Educate parents on correct administration and the importance of completing the course.
▪️ Reassess cases within 24–48 hours when antibiotics are prescribed.
✍️ Conclusion
Antibiotics are not routinely needed in pediatric dentistry, and local treatment is sufficient in most cases. Their use should be reserved for systemic infection, facial cellulitis, medically complex patients, or situations where dental treatment cannot be immediately performed. Adopting evidence-based prescribing practices reduces antimicrobial resistance and ensures high-quality pediatric dental care.
