Managing Pediatric Odontogenic Infections: Diagnosis, Symptoms, and Treatment Guidelines

✅ Summary
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.

✅ Introduction
In pediatric dental practice, odontogenic infections represent a significant clinical concern because children’s immune responses and anatomical characteristics can favor rapid dissemination. The infections typically originate from the pulpal necrosis of deciduous teeth and can progress to abscess formation, facial swelling, or airway compromise in severe cases.
The main goals in management include early diagnosis, infection drainage, and antibiotic therapy when indicated. The selection of appropriate antimicrobials and dosage adjustments for children is vital to ensure safety and efficacy.

✅ Common Pediatric Odontogenic Infections

1. Pulpitis and Periapical Abscess
These are the most prevalent odontogenic infections in children, resulting from deep caries. Acute pulpitis causes spontaneous pain, while periapical abscesses manifest as localized swelling and tenderness.

2. Periodontal Abscess
Occurs due to bacterial accumulation in periodontal pockets or trauma to gingival tissues. It can be localized but painful and often associated with poor oral hygiene.

3. Cellulitis
Represents the diffuse spread of infection through fascial spaces. It is characterized by rapidly spreading swelling, fever, and malaise, requiring immediate systemic antibiotic therapy and sometimes hospitalization.

4. Ludwig’s Angina
A severe, potentially life-threatening infection involving bilateral submandibular, submental, and sublingual spaces. It can compromise the airway and requires emergency surgical drainage and IV antibiotics.

When the pediatric patient presents an oral infection, antibiotics should be administered with the objective of controlling the infection and avoiding serious consequences at a systematic level.

✅ Pharmacological Management in Children
The pharmacological management depends on the severity of the infection, the child’s weight, and the presence of systemic involvement.

📊 Pharmacological Management in Children

Drug	Pediatric Dosage	Indication
Amoxicillin	25–50 mg/kg/day divided every 8 h (max 2 g/day)	First-line for localized odontogenic infections
Amoxicillin-Clavulanate	25–45 mg/kg/day (amoxicillin component) divided every 12 h	Moderate to severe infections or beta-lactamase-producing bacteria
Metronidazole	30 mg/kg/day divided every 8 h	Anaerobic infections; used as adjunct therapy
Clindamycin	20–30 mg/kg/day divided every 8 h	Penicillin-allergic patients or severe infections
Ibuprofen	10 mg/kg every 6–8 h	Analgesia and anti-inflammatory support

📊 Signs and Symptoms of Odontogenic Infections in Children

Infection Type	Main Signs	Main Symptoms
Pulpitis	No swelling; deep caries; sensitive to cold	Sharp, spontaneous pain; worsens at night
Periapical Abscess	Localized swelling; gingival fistula; tooth mobility	Throbbing pain; tenderness on biting; relief after drainage
Periodontal Abscess	Swelling along gingival margin; pus discharge	Localized pain; sensitivity; bad taste in mouth
Cellulitis	Diffuse swelling; redness; warmth; lymphadenopathy	Fever; malaise; facial pain; trismus
Ludwig’s Angina	Bilateral submandibular swelling; elevated tongue	Difficulty breathing; dysphagia; severe pain; fever

💬 Discussion
Pediatric odontogenic infections can progress rapidly due to the high vascularity and loose connective tissue of children’s facial planes. Delayed treatment may lead to severe complications such as airway obstruction, sepsis, or cavernous sinus thrombosis.
Antibiotic stewardship is essential: antibiotics should be prescribed only when systemic involvement or spreading infection is evident. Overuse can promote resistance and microbiome imbalance. Furthermore, parental education about early dental care and caries prevention is fundamental in avoiding such infections.
Recent literature supports combined conservative and pharmacological approaches, emphasizing pulp therapy or extraction as definitive treatments once the infection source is controlled.

Adhering to recommended antibiotic regimens and dosages is crucial to ensure efficacy and minimize the risk of resistance. Always consider patient-specific factors, such as age, weight, and allergy history, when selecting an antibiotic.

✍️ Conclusion
Odontogenic infections in children are preventable yet potentially serious conditions. Accurate clinical diagnosis, timely intervention, and appropriate antibiotic therapy are vital for successful outcomes. Pediatric dentists must be trained to recognize early signs, initiate prompt drainage and medication, and monitor systemic symptoms to prevent complications. Preventive education and regular check-ups remain the most effective long-term strategy.
