Many changes occur in the child from conception to the first year of life. In terms of functional and psychological changes in life, 6 months of age is considered the milestone. The eruption of the first teeth in the oral cavity leads to the rise in curiosity among parents. Teeth present at birth are called the natal teeth. And teeth that erupt within the first 30 days of life are referred to neonatal teeth.
Natal and neonatal teeth may occur due to a disturbance in the biological chronology whose exact etiology is still unknown.
Several factors related to this condition are:
Morphologically, natal and neonatal teeth may be conical, opaque and yellow-brownish in color. Many studies quoted that the dimensions of the crowns of these teeth are smaller than primary teeth under normal conditions.
The terms natal and neonatal teeth, proposed by Massler and Savara (1950), are limited only to the time of the eruption and not to the anatomical, morphological and structural characteristics.
