Why are some babies born with teeth?

Published in Infant Oral Health 2 mins read

Some babies are born with teeth, but the exact reason why is unknown. These teeth are called natal teeth.

Understanding Natal Teeth

While the cause remains unclear, there are some factors that may be associated with the development of natal teeth:

  • Unknown Cause: The primary point to remember is that the precise reason for natal teeth is still a mystery.
  • Associated Health Conditions: There is some evidence to suggest that natal teeth are more prevalent in children who have specific health conditions that impact growth. These include:
    • Sotos Syndrome: A genetic disorder characterized by excessive growth during childhood.
    • Ellis-van Creveld Syndrome: Also known as chondroectodermal dysplasia, this genetic condition affects bone and limb development.
    • Pachyonychia Congenita: A rare genetic disorder causing thickening of the nails.
    • Hallermann-Streiff Syndrome: A rare disorder impacting bone development.

Further Considerations:

Aspect Details
Prevalence Natal teeth are rare, occurring in roughly 1 in every 2,000 to 3,000 births.
Appearance Natal teeth usually appear in the lower gum. They might look like normal baby teeth, but sometimes they're small and loosely attached.
Treatment Management varies, depending on if the teeth are interfering with feeding, posing risk of injury, or are too loose.
Genetic Factors More research is needed to determine the role of genetics.

Key Takeaway:

The presence of natal teeth in babies is not well understood and further study is needed to determine the exact cause.
