Natal Teeth
A 9-day-old boy was brought in for routine care. His mother had noticed these teeth at the child's birth. There were no other remarkable physical findings. Natal teeth occur in 1:700 to 1:6000 births, write Howard Fischer, MD, and Ahdi Amer, MD, of Children's Hospital of Michigan in Detroit. Such teeth are most often seen in the mandibular incisor area, often in pairs.

Such teeth are most often seen in the mandibular incisor area, often in pairs. They are not extra, or supernumerary, but are part of the primary dentition in more than 90% of affected patients. The teeth are often mobile because of poor root development. The crowns often show incomplete enamel development.1
Natal teeth may be found in various syndromes: Ellis-van Creveld syndrome (chondroectodermal dysplasia), Jadassohn-Lewandowski syndrome (pachyonychia congenita), and Hallerman-Streiff syndrome (oculomandibulofacial syndrome with hypotrichosis).2
It is preferable to maintain these teeth, which allow the dental arch to develop normally.3 Sometimes they spontaneously exfoliate. Highly mobile teeth may be aspirated and are therefore usually extracted.
Julius Caesar, Hannibal, and Napoleon all had natal teeth.4
