Summary

Natal teeth, present at birth, are a rare phenomenon occurring in approximately 1:3,400 births. Most natal teeth are normal primary incisors and may require extraction due to feeding difficulties or aspiration risks.

Area of Science:

  • Pediatric Dentistry
  • Neonatology
  • Oral and Maxillofacial Surgery

Background:

  • Natal teeth are defined as teeth present at birth, distinct from neonatal teeth erupted within the first month.
  • The normal primary tooth eruption typically begins with mandibular incisors around 6 months of age.
  • This study investigates the clinical and structural characteristics, etiology, and management of natal teeth.

Observation:

  • A retrospective study of 17,000 infants identified 5 cases of natal teeth (incidence 1:3,400).
  • The cases involved 14 natal teeth, predominantly incisors (70%), with a slight male predilection (4:1).
  • Most natal teeth were mobile and extracted due to risks of aspiration, feeding issues, or tongue ulceration.

Findings:

  • Natal teeth are rare, with incisors being the most frequently affected teeth.

  • The majority (nearly 90%) of natal teeth are normal primary teeth, not supernumerary.
  • No specific morphological syndromes were identified in the observed cases.

    • Implications:

    • Radiographic examination is crucial for differentiating between normal primary and supernumerary natal teeth.
    • Extraction decisions for natal teeth should consider tooth mobility, local/systemic complications, and parental input.
    • While a direct link to systemic disorders is unproven, potential associations with certain syndromes warrant consideration.
