What is the most common dental anomaly related to tooth number?

Hypodontia is recognized as the most common dental anomaly related to tooth number. It refers to the condition where one or more teeth are missing due to developmental issues. This anomaly is particularly significant as it impacts both the aesthetics and function of the dentition.

The prevalence of hypodontia makes it more common compared to other anomalies such as anodontia, which involves the complete absence of teeth, or hyperdontia, which is characterized by having an excess number of teeth. Microdontia, on the other hand, refers to teeth that are smaller than average, but it does not affect the number of teeth present. Given these definitions, hypodontia stands out as the most frequent condition concerning tooth number abnormalities, impacting a larger segment of the population.
