What is a condition associated with the absence of a tooth due to developmental failure?

Anodontia refers specifically to the complete absence of all teeth due to developmental failure. It is a rare condition that occurs when teeth do not form during the development process. Individuals with anodontia may experience significant challenges with eating, speaking, and overall dental health due to the total lack of a dental structure.

It's important to differentiate this condition from others like hypodontia, which involves the absence of one or more teeth but not all, and dental agenesis, which is a broader term that can encompass both anodontia and hypodontia. Supernumerary teeth, on the other hand, refer to the presence of extra teeth beyond the normal dental count, which is the opposite condition. Therefore, anodontia is the most accurate term to describe the complete absence of teeth due to developmental failure.
