On average, males have larger teeth than females. This difference, known as sexual dimorphism, is observed in many human populations. However, the extent of this difference varies among populations.
While the overall size of male teeth tends to be greater, it's crucial to note that the size difference isn't uniform across all teeth. Some studies indicate that certain teeth, such as canines and incisors, exhibit a more pronounced size difference between the sexes than others. [See references below for details on specific studies]
Factors Influencing Tooth Size
Several factors contribute to tooth size variations beyond gender:
- Genetics: Genetic inheritance plays a significant role in determining overall tooth size and shape.
- Ethnicity: Different ethnic groups may exhibit varying average tooth sizes.
- Age: Tooth size can change slightly throughout life.
- Individual Variation: Significant variation exists even within the same gender and ethnic group.
Understanding Sexual Dimorphism in Teeth
Sexual dimorphism in teeth is a common phenomenon across many animal species. While the exact evolutionary reasons behind this are still debated, several hypotheses exist, potentially involving differences in diet, mating behavior, or physical strength. In humans, the size difference is generally subtle and doesn't drastically impact everyday function.
The provided references highlight numerous studies examining tooth size differences between genders. Some studies focus on specific populations, while others analyze broader trends across diverse groups. Analyzing various populations shows that, while there is a general trend of males having larger teeth, the magnitude of this difference can vary.

- Multiple studies referenced highlight that males tend to possess larger tooth crowns than females in modern human populations. The degree of this difference varies considerably depending on population and specific teeth analyzed. Several of the links provided offer more in-depth studies of this topic. One specifically notes that, although there is no difference in lower incisor widths between genders, the larger size of other teeth in males still creates a substantial overall difference in tooth size.
