Natal teeth are teeth that are already present at the time of birth. They are different than neonatal teeth, which grow in during the first 30 days after birth.

Natal teeth are relatively uncommon, appearing in about one in every 2,000 to 3,000 births. Although the majority of natal teeth are isolated incidents, 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 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, especially if the tooth is loose and the child runs a risk of aspiration, or "breathing in" the tooth.

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

If the teeth are not removed, keep them clean by gently wiping the gums and teeth with a clean, damp cloth. Examine the infant's gums and tongue frequently to make sure the teeth are not causing injury.
