Management of Upper Lip Frenulum Injuries in Infants

Initial Assessment and Wound Management

The American Academy of Pediatrics recommends assessing for child abuse in children younger than 5 years with trauma affecting the lips, gingiva, tongue, and palate, as the mechanism of injury should be consistent with the developmental stage 1, 2
Most upper lip frenulum lacerations in infants heal spontaneously without intervention and require only supportive care with wound hygiene and dietary modifications, according to the American Academy of Pediatrics 1
The wound should be examined to determine the depth and extent of the laceration, active bleeding, associated dental or gingival injuries, and signs of more extensive facial trauma, as recommended by the American Academy of Pediatrics 1, 2

The American Academy of Pediatrics recommends a soft diet for 10 days following the injury, avoiding hard, sharp, or irritating foods that could disrupt healing, and restricting pacifier or digit sucking for the first 10 days 1, 2
Maintaining good oral hygiene with gentle cleaning is crucial to optimize healing, as suggested by the American Academy of Pediatrics 1, 2

Caregivers should watch for signs of infection, such as gingival swelling, increased pain, purulent drainage, or fever, and breathing difficulties, though unlikely with isolated intraoral laceration, as recommended by the American Academy of Pediatrics 1
Delayed healing beyond 10-14 days should be monitored, and re-evaluation is necessary if any concerning symptoms develop, according to the American Academy of Pediatrics 1

Immediate referral to a pediatric plastic surgeon or pediatric surgeon is not necessary for simple frenulum lacerations, but referral is necessary if extensive gingival or facial swelling develops, multiple teeth are affected or displaced, or there is concern for deeper tissue involvement requiring reconstruction, as recommended by the American Academy of Pediatrics 2, 3, 4
Referral is also necessary if signs of infection do not respond to conservative management, according to the American Academy of Pediatrics 1

Prescribe or recommend age‑appropriate analgesics for children with lacerations, with the expectation that pain should gradually lessen over the first few days; persistent or worsening pain may signal infection or other complications. The recommendation follows pediatric wound‑care guidance and is supported by evidence from the Pediatrics journal (2012) 5
