Dental Emergencies in Pediatric Patients

Critical Signs Requiring Same-Day/Immediate Dental Referral

• The American Academy of Pediatric Dentistry recommends immediate replantation of an avulsed permanent tooth within minutes to hours for optimal prognosis 1, 2
• The American Academy of Pediatric Dentistry suggests that crown fracture with visible pulp exposure requires immediate pulp therapy to preserve tooth vitality, particularly in immature permanent teeth 1, 3
• The American Academy of Pediatric Dentistry indicates that multiple teeth moving together as a segment may indicate alveolar bone fracture requiring immediate repositioning and splinting 4, 5
• The American Academy of Pediatric Dentistry recommends urgent repositioning of tooth displacement interfering with occlusion to prevent permanent malocclusion 4, 6, 5
• The American Academy of Pediatric Dentistry suggests that severe extrusive luxation or severe intrusive luxation where the tooth is not visible clinically requires immediate dental intervention 4, 6
• The American Academy of Pediatric Dentistry recommends immediate referral for extensive gingival or facial swelling developing after dental trauma or in association with a tooth, indicating potential abscess formation 4, 5
• The American Academy of Pediatric Dentistry indicates that parulis appearing on the gingiva adjacent to a previously injured tooth signals pulpal necrosis requiring extraction evaluation 4, 2
• The American Academy of Pediatric Dentistry suggests that gingival swelling with increased tooth mobility may indicate pulpal necrosis and potential periapical abscess 2, 5
• The American Academy of Pediatric Dentistry recommends immediate repositioning of abnormal jaw movement with inability to close the jaw, which may indicate mandibular dislocation 7, 5
• The American Academy of Pediatric Dentistry suggests that excessive tooth mobility with concern for aspiration of the crown portion requires immediate evaluation 4

Signs Requiring Dental Referral Within Days (Not Immediate)

• The American Academy of Pediatric Dentistry recommends referral within a few days for gray tooth discoloration developing after trauma, indicating pulpal hemorrhage and potential necrosis 4, 5
• The American Academy of Pediatric Dentistry suggests that tooth sensitivity with exposed dentin from enamel-dentin fractures should be seen within a few days to cover exposed dentin and reduce bacterial contamination risk 1, 3
• The American Academy of Pediatric Dentistry indicates that subluxation with tooth mobility but no displacement requires monitoring and referral within days if discoloration or parulis develops 4, 6

Common Pitfalls and Clinical Pearls

• The American Academy of Pediatric Dentistry recommends never replanting an avulsed primary tooth, as this risks damage to the underlying permanent tooth germ, whereas permanent tooth avulsion requires immediate replantation 1, 3, 2
• The American Academy of Pediatric Dentistry suggests that primary tooth intrusion typically re-erupts spontaneously and requires observation rather than immediate intervention, unlike permanent tooth intrusion which may need orthodontic repositioning 4, 6
• The American Academy of Pediatric Dentistry indicates that children may not report pain from a necrotic tooth, so caregivers must watch for visual signs including discoloration, swelling, and parulis rather than relying on pain complaints 4, 2
• The American Academy of Pediatric Dentistry recommends suspicion for non-accidental injury in cases of trauma affecting the oral cavity in children younger than 5 years, particularly with severe tooth injury or inconsistent mechanism 7, 5

Evidence‑Based Management of Extruded and Intruded Permanent Teeth

Extruded Permanent Teeth – Initial Repositioning

• Apply gentle digital pressure to reposition a minimally extruded tooth back into its socket at the time of injury. This can be performed immediately in the field. 8
• When extrusion is excessive, the tooth must be repositioned with dental forceps by a dentist; an immediate referral is required. 8, 9
• After repositioning, confirm that the tooth does not interfere with occlusion by having the patient pronounce “cheese” or the letter “e” to ensure posterior teeth can fully interdigitate. 9, 10

Extruded Permanent Teeth – Stabilization (Splinting)

• Stabilize the repositioned tooth with a flexible splint for exactly 2 weeks; the duration is critical for optimal healing. 8, 9
• The treating dentist decides whether pulp therapy is needed based on the tooth’s root maturity (immature vs. mature). 9

Extruded Permanent Teeth – Follow‑up Monitoring

• Monitor closely for signs of pulpal necrosis, including gingival swelling, increased mobility, formation of a parulis, or gray discoloration of the crown. These complications may appear weeks to months after injury. 8

Intruded Permanent Teeth – Management Based on Root Development

• For mild intrusion of teeth with incomplete root formation, allow spontaneous re‑eruption while providing close clinical monitoring. 8
• Bleeding from the gingival sulcus is an expected finding in these cases. 8
• If visible re‑eruption does not occur within a few weeks, proceed with orthodontic or surgical repositioning. 8

Intruded Permanent Teeth – Radiographic Assessment & Risks

• In severe intrusion (tooth not clinically visible), obtain intra‑oral radiography immediately to determine the tooth’s position within the alveolus. 8, 10
• Recognize the risk of ankylosis (fusion of tooth to bone); if ankylosis develops, extraction may be necessary to prevent alveolar ridge distortion, followed by placement of an artificial tooth. 8

Adjunctive Management – Analgesia & Antibiotics for Avulsion (Relevant Reference)

• Provide appropriate analgesia for pain control (e.g., ibuprofen or acetaminophen) as per standard pediatric dental practice. 10
• Systemic antibiotics are not routinely indicated for extrusion or intrusion injuries; however, for avulsed permanent teeth after re‑implantation, antibiotics are recommended: doxycycline for patients > 12 years, penicillin for patients ≤ 12 years, and clindamycin for penicillin‑allergic individuals. 10
