Definition

Teeth already present at the time of birth (natal) or erupt during the first 30 days (neonatal).

Alternative Names
Fetal teeth; Neonatal teeth

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, especially if the tooth is loose and the runs a risk of aspiration or breathing in of the tooth.

Common Causes

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

Home Care
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 baby is not injuring his or her tongue.

Call your health care provider if

an infant with natal teeth that have been left in place develops a sore tongue or mouth.
other symptoms develop.

What to expect at your health care provider's office

The medical history will be obtained and a physical examination performed.

Documenting natal teeth in detail may include:

Were any other family members born with teeth?
Did they later develop any problems?
Are any other symptoms present?

Note: This finding is usually discovered by the health care provider during the initial examination of the infant, and often no further documentation is needed other than just to note that there were teeth present at birth.

The physical examination will include thorough examination of the mouth, and dental X-rays may be considered. If there are signs of any condition that can be associated with natal teeth, examination and testing for that condition will be performed.

Note: Most often natal teeth occurs as an isolated incident.

After seeing your health care provider:

If a diagnosis was made by your health care provider associated with the presence of natal teeth, you may want to note that diagnosis in your personal medical record.
