Are Big Teeth Rare?
The rarity of big teeth depends on what you mean by "big." If we're talking about teeth significantly larger than average (macrodontia), then yes, it is relatively rare. However, the definition of "big" is subjective and context-dependent.
The term "big teeth" can be interpreted in several ways:
-
Clinically Significant Macrodontia: This refers to teeth that are demonstrably larger than the average size for a person's age and genetics, often requiring dental intervention. Studies suggest that macrodontia affects only 0.03 to 1.9 percent of the global population (Source: Healthline article on Big Teeth). In these cases, large teeth are indeed uncommon.
-
Subjectively Large Teeth: Some individuals may perceive their teeth as too large, even if they fall within the normal size range. This is a matter of personal perception and aesthetics, rather than a clinical diagnosis. The perception of teeth size can be influenced by facial proportions and overall smile aesthetics.

-
Large Teeth in Specific Contexts: The rarity of "big teeth" can also change based on the context. For instance, while large megalodon teeth are relatively common compared to other megalodon fossils, large, high-quality megalodon teeth are rare and highly valued.

(Source: NCBI article on dentigerous cysts).
Conditions Associated with Large Teeth
Some genetic conditions are characterized by macrodontia. For example, KBG syndrome is a rare genetic disorder with macrodontia as a key feature. (Sources: MedlinePlus Genetics on KBG syndrome, NORD on KBG syndrome). Conversely, Williams syndrome is associated with small teeth, highlighting the diverse genetic influences on tooth size. (Source: Cleveland Clinic on Williams syndrome).
Conclusion
The answer to whether big teeth are rare is nuanced. Clinically significant macrodontia is relatively uncommon. However, the perception of "big teeth" is subjective, and the rarity can depend greatly on context.
