About 1 in 289 babies is born with at least one tooth already visible. These are called natal teeth, and while they can startle new parents, they’re a well-documented occurrence that usually doesn’t signal a serious problem. A global meta-analysis published in The Journal of the American Dental Association calculated the worldwide prevalence at roughly 35 per 10,000 live births.
Natal Teeth vs. Neonatal Teeth
Teeth present at the moment of birth are natal teeth. Teeth that erupt within the first 30 days of life are neonatal teeth. Neonatal teeth are far less common, showing up in roughly 1 in 2,212 newborns. When people ask about babies “born with teeth,” they’re almost always talking about natal teeth, and those are the focus of most clinical attention.
Rates Vary by Region
The 1-in-289 figure is a global average, and actual rates differ significantly depending on geography. North America has the highest reported prevalence at about 75 per 10,000 births, while Asia has the lowest at roughly 11 per 10,000. Europe and South America fall in between. These differences likely reflect a combination of genetics, reporting practices, and study design rather than one single explanation.
Which Teeth Appear and What They Look Like
Natal teeth almost always show up in the lower front of the mouth, in the spot where a baby’s first teeth would normally emerge around six months of age. At least 90% of natal teeth are regular baby teeth (primary teeth) that have simply erupted early. No more than 10% are extra, supernumerary teeth that fall outside the normal set of 20 primary teeth. This distinction matters because if the tooth is part of the normal set, removing it means the child won’t have a replacement in that spot until the permanent tooth comes in years later.
Natal teeth can look and feel different from the teeth you’d see in an older infant. They’re often smaller, discolored, or poorly rooted. Some are so loosely attached to the gum that they wobble noticeably. Others are firmly anchored and function like any early baby tooth would.
Why Some Babies Are Born With Teeth
In most cases, there’s no clear reason. The tooth bud simply sits closer to the gum surface than usual, so it breaks through earlier than expected. A family history of natal teeth increases the likelihood, suggesting a genetic component.
In a small number of cases, natal teeth are associated with an underlying genetic condition. The list of linked syndromes is long and includes Ellis-van Creveld syndrome, Pierre Robin syndrome, Sotos syndrome, Pfeiffer syndrome, and several forms of ectodermal dysplasia. These conditions come with many other visible signs, so natal teeth alone are rarely the first or only clue. If a baby is otherwise healthy and developing normally, the teeth are typically an isolated finding.
Potential Complications
The biggest concern with natal teeth is what they can do to the soft tissue of a newborn’s mouth. During sucking and swallowing, the underside of the tongue rubs repeatedly against the tooth’s edge. This friction can create an ulcer on the bottom surface of the tongue, a condition known as Riga-Fede disease. The ulcer can grow to several millimeters across and become painful enough that the baby refuses to feed, raising the risk of nutritional problems and dehydration.
Loosely attached teeth carry a second risk: aspiration. A tooth with very little root structure could detach and be inhaled into the airway. This is rare, but it’s the primary reason doctors sometimes recommend removing a wobbly natal tooth rather than leaving it in place.
When Teeth Stay and When They’re Removed
The decision depends on how firmly the tooth is rooted and whether it’s causing problems. A well-anchored natal tooth that isn’t injuring the baby’s tongue or interfering with feeding is generally left alone. Leaving it preserves the spacing for the rest of the primary teeth.
Removal is considered when the tooth is extremely loose (posing an aspiration risk), when it’s causing tongue ulceration that won’t heal, or when the baby can’t breastfeed or bottle-feed effectively. Extraction in a newborn is a quick procedure because the root, if present at all, is minimal. Your pediatrician or a pediatric dentist will typically wait until the baby is at least 10 days old to allow vitamin K levels to stabilize and reduce bleeding risk.
Breastfeeding With Natal Teeth
Many parents worry that a baby born with teeth won’t be able to breastfeed, or that nursing will be painful. In practice, a properly latched baby tucks the tongue over the lower gum, which covers the teeth during active feeding. Biting tends to happen at the end of a feeding when the baby is no longer actively swallowing.
A few strategies can help. Before nursing, you can soothe the gums with a cold, wet washcloth or a clean finger massage. During the feeding, make sure the baby is well supported and deeply latched. If you notice the tongue shifting position, gently inserting a finger into the corner of the baby’s mouth redirects the bite away from the breast. If the baby does clamp down, a firm “no” followed by briefly turning the baby away teaches them quickly that biting stops the feeding. Most parents find that with a few adjustments, breastfeeding continues without major issues.
Long-Term Outlook
Babies born with teeth generally have completely normal dental development afterward. If the natal tooth was a primary tooth and it was removed, the gap stays empty until the permanent tooth erupts, usually around age six or seven. If the tooth was left in place, it sheds on the same schedule as any other baby tooth. There’s no evidence that having natal teeth increases the risk of cavities, misalignment, or other dental problems later in childhood.
