A baby starts forming its first teeth when it is just a six-week-old fetus in the womb (1). The teeth develop in the gums and are not usually visible until they are fully formed, months after the baby is born. But sometimes, the baby is born with a pair of teeth that you can see.
These teeth are called natal teeth and are a rare occurrence. In this post, Momjunction tells you what natal teeth are, what causes their formation, and how they affect the baby’s health and overall development.
What Are Natal Teeth And Are They Common?
Natal teeth, which are highly uncommon, are teeth that are present when the baby is born (1). The probability of a child being born with natal teeth can range from one in 7000 to one in 30,000 based on different studies (2). Usually, there are no more than three natal teeth, and the chances of an infant having natal teeth are the same, irrespective of gender.
Can Natal Teeth Cause Problems To The Baby?
Yes. Natal teeth may cause complications such as:
- Trouble latching to nipple: It is the leading complication observed among babies born with teeth. The presence of teeth can make it hard for the little one to properly latch onto the breast or bottle nipple, thus preventing uninterrupted feeding.
- Poor feeding and impact on health: Since the baby does not feed properly, he does not get the essential nutrients. This could affect the baby’s overall development.
- Fussiness: In case the teeth are embedded within the gums, the baby experiences pain that is similar to teething pain. This makes the baby irritable and fussy.
- Biting the nipple: A baby with natal teeth may nip either at the breast or the bottle nipple. Repeated biting may damage the bottle nipple or make breastfeeding difficult.
- Choking: A loose natal teeth could break and fall into the windpipe, resulting in fatal choking.

How Are Natal Teeth Removed?
Surgery is the only way to remove natal teeth. Keep reading for more information on the procedure (11):
- Pre-operative preparations: The surgery is done after the baby is at least ten days when the baby develops intestinal flora (bacteria) that produces vitamin K that enables blood coagulation. This is essential for faster healing and preventing hemorrhage (excessive blood loss) during surgery (12). Usually, babies also receive vitamin K supplements before surgery.
- Natal teeth removal: The operation is performed under local anesthesia, which provides enough sedation to keep the baby calm through the surgery.
- Post-operative care: More vitamin K could be administered intramuscularly, depending on the rate of healing. The baby is discharged within few hours, and follow-up happens every week.
The pediatric dentist decides whether or not to remove natal teeth, after examining the extent of their interference in baby’s growth and development. If the teeth are strongly rooted and have no impact on baby’s feeding, then surgery may not be required.
Do Primary Teeth replace Natal Teeth?
About 90-99% of natal teeth are primary teeth that have emerged before time. Only 1-10% are supernumerary teeth, or extra teeth in the mouth.
If the baby’s natal teeth are primary, they will be replaced by permanent teeth later. Otherwise, the baby will grow primary teeth first, followed by permanent teeth after the loss of the primaries.

What Are The Types Of Natal Teeth?
The following are the four types of natal teeth (3):
- Fully erupted: The teeth are entirely out of the gums and visible easily. The teeth do not move when touched and are firmly attached to the gums.
- Loose and fully erupted: Teeth are fully visible but are loosely attached to the gums, indicating the absence of roots or partial rooting.
- Partially erupted: An edge of the tooth’s crown is visible through the gums. The remainder of the teeth is embedded in the gums.
- Unerupted but visible: The teeth are entrenched but visible as a white bump on the gums.
Can Any Teeth Erupt As Natal Teeth?
Only the below-mentioned teeth emerge as natal teeth (4):
- Lower central incisors – 85%
- Upper incisors – 11%
- Lower canines and molars – 3%
- Upper canines and molars – 1%
The two lower central incisors are the most common types of natal teeth. It is significantly rare to be born with multiple sets of natal teeth.
Why Are Some Infants Born With Teeth?
The following are the most common reasons for babies having natal teeth (5):

- Hereditary: A baby is quite likely to be born with natal teeth if its parent, sibling or an immediate relative had teeth at birth.
- Ellis-van Creveld syndrome: Also called chondroectodermal dysplasia (6), it is a genetic bone disorder that causes a host of congenital abnormalities such as extra fingers, a total absence of hair, and presence of teeth. Ellis-van Creveld syndrome is rare and commonly observed in isolated populations.
- Pierre Robin syndrome: A genetic disorder where the baby is born with an abnormally small lower jaw. One of the several complications of the condition is the presence of teeth at birth (7).
- Hallermann-Streiff syndrome or oculomandibulo-dyscephaly with hypotrichosis is a rare congenital genetic disorder that causes deformities of the skull like a shorter jaw, arched mouth palate and natal teeth (8). This condition is so rare that its exact causes are unknown and even treatment options are limited.
- Sotos syndrome is a genetic disease that causes accelerated growth during infancy and toddlerhood. Babies born with the condition often display the presence of teeth at birth (9).
- Jadassohn–Lewandowski syndrome, also called pachyonychia congenita, is caused by unfavorable genetic mutations. Infants born with the condition display thick nails and the presence of natal teeth (10).
- General jaw deformities: Natal teeth are also present in newborns with jaw abnormalities like cleft lip and cleft palate.
- Endocrine problems: Congenital hormonal problems can also cause natal teeth.
- Congenital and maternal infections: If the baby is born with an infection (contracted through mother), then he may display natal teeth as a side effect. Example of such an illness is congenital syphilis. Also, if a mother has suffered from a serious illness or high fevers during pregnancy, then the infant could have natal teeth at birth.
What Is The Difference Between Natal And Neonatal Teeth?
Natal teeth are present at birth while neonatal teeth emerge within the first month (30 days) of the infant’s life. Natal teeth are three times more common than neonatal teeth, which are similar to natal teeth in appearance and where they emerge. Causes, complications, and treatment of neonatal teeth are also identical to that of natal teeth.

Can Natal And Neonatal Teeth Happen Simultaneously?
The two can happen together, but it is an extremely rare condition. The emergence of the two in succession is mainly observed in complex congenital genetic disorders.
Natal teeth often come across as alarming and disconcerting to the parents. However, the condition is benign and treatable without complications. If the baby has no problem with the teeth, the doctor may leave them intact. There is no harm even if the teeth are removed, for the baby will anyway develop permanent teeth later in life.
