Introduction: Intrusive luxation is one of the most severe forms of traumatic dental injuries in early childhood. Management is challenging because of the relationship between primary teeth and the developing permanent tooth germ. Current guidelines favor conservative approaches, particularly in very young patients.

Methods: An 18 month-old girl was referred following a domestic fall. Clinical and radiographic examinations revealed intrusive luxation of multiple maxillary primary incisors associated with a labial alveolar bone fracture and soft-tissue injuries. Emergency management included oral disinfection and suturing of a lower labial mucosal laceration. A conservative approach based on clinical monitoring for spontaneous re-eruption was adopted.

Results: At the one-week follow-up, complete resolution of edema and satisfactory soft-tissue healing were observed. The two-month follow-up demonstrated full spontaneous re-eruption of all intruded primary incisors, with complete gingival healing and no evidence of pain and infection.

Discussion: This case illustrates the high potential for spontaneous re-eruption of intruded primary incisors in very young children, even when associated with an alveolar bone fracture. Conservative management with careful clinical monitoring can lead to favorable outcomes, in accordance with current IADT recommendations.
