Human tooth development having negative effects on human health, including, but not limited to, fetal development. As shown in animal studies which mimic human enamel, the mother’s consumption of products with BPA during pregnancy can lead to the child’s tooth development being obstructed. Those children are shown to be prone to incisor and first molar hypomineralization, a weakened state of the enamel. Additionally, it is most important for mother’s to avoid BPA during pregnancy, but also avoid BPA-use in the child’s products up to five months of age. Anodontia is a complete lack of tooth development, and hypodontia is a lack of some
Human tooth development One of the earliest signs in the formation of a tooth that can be seen microscopically is the distinction between the vestibular lamina and the dental lamina. The dental lamina connects the developing tooth bud to the epithelial layer of the mouth for a significant time. This is regarded as the initiation stage. 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. Typically, this occurs when the fetus is around 8 weeks old. The tooth bud itself
