In 1950, Massler and Savara introduced the now commonly used terms “natal teeth” for teeth present at birth and “neonatal teeth” for teeth that erupt within the first 30 days of life.
The most common natal and neonatal teeth are the mandibular central incisors.
In most cases, these teeth represent the true primary teeth and are not supernumerary teeth.
In King and Lee’s4 1989 report, 44 subjects presented with natal and neonatal teeth that were part of the primary dentition. In light of this knowledge, these teeth should be left in the mouth to avoid future space management issues.
On occasion, they will exfoliate spontaneously or require extraction because of excessive mobility, concerns regarding aspiration or the loss of attachment with subsequent development of abscess.

They may also be extracted to alleviate feeding difficulties including Riga-Fede disease, where the presence of natal or neonatal teeth in association with nursing or sucking leads to ulceration of the ventral surface of the tongue.
