Natal teeth, defined as teeth present at birth, are rare, with an estimated incidence of 1 in 2,000-3,500 live births. While often sporadic, familial cases suggest a genetic predisposition. We present a case of a neonate with natal teeth and a strong positive family history spanning three generations, highlighting potential genetic and clinical implications. A full-term neonate presented with two lower central incisors at birth. The teeth were firmly attached, non-mobile, and did not interfere with feeding. Family history revealed multiple relatives across three generations with natal teeth. The child had no dysmorphic features or systemic anomalies. No syndromic associations were identified. This case highlights the heritable nature of natal teeth and the need for genetic consideration in such presentations. Family history plays a crucial role in differentiating isolated cases from syndromic conditions.
