Sudden Onset of Abnormal Jaw Movement in a Child

Initial Assessment and Emergency Intervention

The American Academy of Pediatrics recommends checking airway patency and breathing, as abnormal jaw movements can compromise the airway, particularly if associated with trauma or seizure activity 1
Assess for acute trauma, examining for facial injuries, dental trauma, or mandibular fractures that could cause abnormal jaw positioning or movement, as recommended by the American Academy of Pediatrics 2, 3
Evaluate for active seizure, as tonic-clonic seizures commonly cause rhythmic jaw movements and require immediate seizure management, according to the American Heart Association 1

Examine for mandibular dislocation or luxation, as the jaw may be displaced and unable to close properly, requiring immediate repositioning, as suggested by the American Academy of Pediatrics 3, 4
Assess dental injuries systematically, looking for missing teeth, tooth mobility, displaced teeth, gum bleeding, and visible fractures, as these can alter jaw mechanics and cause abnormal movement patterns, according to the American Dental Association 5
Check for alveolar fractures, as multiple teeth moving together as a segment indicates alveolar bone fracture requiring immediate dental referral for repositioning and splinting, as recommended by the American Academy of Pediatrics 3, 4
Screen for child abuse, as trauma affecting the oral cavity in children younger than 5 years should raise suspicion for non-accidental injury, according to the American Academy of Pediatrics 6, 5

Referral to dentist or oral surgeon is indicated for jaw dislocation or luxation, multiple teeth moving together (alveolar fracture), tooth displacement interfering with bite/occlusion, or inability to close the jaw properly, as recommended by the American Dental Association 3, 4, 5, 7
Orthopantomogram (OPG) is indicated for suspected TMJ pathology, but should not be performed before age 6 unless clinically urgent, as suggested by the American Academy of Pediatric Dentistry 8
Referral to pediatric dentist or orthodontist is appropriate for persistent malocclusion, TMJ dysfunction, or when clinical examination suggests structural abnormality, according to the American Association of Orthodontists 5, 8

Ensure airway is patent and child is stable, as recommended by the American Heart Association 1
Determine if trauma occurred, and if so, examine for dental injuries, jaw dislocation, alveolar fractures, and refer immediately to dentist/oral surgeon for displaced jaw or significant dental trauma, as suggested by the American Academy of Pediatrics 3, 4, 5
