The bud stage is characterized by the appearance of a tooth bud without a clear arrangement of cells. The stage technically begins once epithelial cells proliferate into the ectomesenchyme of the jaw. [1] Typically, this occurs when the fetus is around 8 weeks old. [22] The tooth bud itself is the group of cells at the periphery of the dental ...
The incidence of neonatal teeth varies considerably, between 1:700 and 1:30,000 depending on the type of study; the highest prevalence is found in the only study that relies on personal examination of patients. [3] Natal teeth, and neonatal teeth, can be the baby's normal deciduous teeth, sprouting prematurely. [4]
This diminishes the strength of the tooth which is called demineralization. For the outer layer of the tooth to reach cavitation, there is a breakdown of the enamel structure that allows the influx of the cariogenic bacteria. As cavitation progresses into dentine, the dental caries lesion becomes more severe, and this may cause tooth pain.
Although tooth eruption occurs at different times for different people, a general eruption timeline exists. The tooth buds of baby teeth start to develop around 6 weeks of pregnancy.

Misplaced (ectopic) positioning of the adult teeth may be discovered upon examination or a radiograph.
This condition can cause teeth to be discolored (most often a blue-gray or yellow-brown color) and translucent, giving teeth an opalescent sheen. [ 2 ] [ 3 ] [ 8 ] [ 5 ] [ 9 ] Teeth are also weaker than normal, making them prone to rapid wear, breakage, and loss.
