What is the term for the condition of having missing teeth?

The condition of having missing teeth is referred to as hypodontia. This term specifically describes a situation where one or more teeth are absent due to developmental issues. Hypodontia can affect both primary (baby) teeth and permanent teeth and can vary in severity, where individual teeth may be missing or in some cases, multiple teeth may be absent.

The other terms relate to different dental conditions: macrodontia denotes excessively large teeth, microdontia refers to teeth that are smaller than normal, and anodontia indicates a complete absence of teeth, which is a more severe condition than hypodontia. Thus, hypodontia is the appropriate term for a situation where there are some missing teeth, whereas anodontia involves the absence of all teeth.
