Natal teeth

Alternative names:

fetal teeth

Definition:

Deciduous (primary, or "baby") teeth already present at the time of birth.

Considerations:

Natal teeth are relatively uncommon, appearing once out of every 2000 to 3000 births. Although the majority of natal teeth are isolated incidences, their presence may be associated with some syndromes.

Natal teeth generally develop on the lower gum where the central incisors will be. They have little root structure and are attached to the margin of the gum by soft tissue and so are often wobbly.

Natal teeth are usually not well formed but they are firm enough that, because of their placement, they may cause irritation and trauma to the infant's tongue while he is nursing. Natal teeth may also be uncomfortable for a nursing mother.

Frequently, natal teeth are removed shortly after birth while the newborn infant is still in the hospital.

Common causes:

• isolated instance (most common)
• Ellis-van Creveld syndrome
• Hallermann-Streiff syndrome
• Pierre Robin syndrome
• Soto's syndrome
