A delay in tooth development may also serve as an indication, whereby the absence of an adult successor slows down the normal resorption of the roots of the baby teeth, which is the progressive loss of parts of the tooth. Misplaced (ectopic) positioning of the adult teeth may be discovered upon examination or a radiograph.
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.

[3] Natal teeth, and neonatal teeth, can be the baby's normal deciduous teeth, sprouting prematurely. [4]
The hair is often light-coloured, brittle, and slow-growing. This condition is also characterized by absent teeth or teeth that are malformed. Hypohidrotic ectodermal dysplasia is the most common form of ectodermal dysplasia in humans. It is estimated to affect at least 1 in 17,000 people worldwide. [citation needed]
Clinically, both the baby (primary) and adult (permanent) teeth often appear amber coloured and translucent, and show signs of severe attrition. Primary teeth have a more obvious appearance as they have a thinner layer of enamel overlying dentine, hence the abnormal color of dentine is more noticeable. [2]
Diagnosing ED usually involves a clinical examination focused on core symptoms, such as lack of sweating, specific dental and hair abnormalities, and characteristic facial features.
