Teeth Differences Based On Race & Sex?

10 Dec Teeth Differences Based On Race & Sex?

You might think that all teeth are the same. However, that’s not necessarily true. The structure of your teeth can vary depending on several factors. Two key factors are your race and your sex. Find out what are the main teeth differences between different races and different sexes.

Major Teeth Differences in Race

When it comes to different races, there are several teeth differences. Before you can understand those differences, you should realize that there are six main races. However, the most significant teeth differences occur between black, white, and American Indian individuals. While there are differences among the other races, they are more difficult to explain.

All of the differences arose because of evolution. Over time, these isolated racial groups developed independent genetic changes. Some of these changes affected their teeth. Today, you can still see these genetic differences. However, travel is changing things. The isolation that existed centuries ago is no longer there. To travel from one country to another, you can hop on a plane and arrive in a few hours. As different races have children together, those teeth differences become less obvious.

Despite the lack of isolation, there are still enough differences for specialists to tell one race from another by their teeth. Usually, an anthropologist can tell the difference. However, you can learn the differences too. Here are a few key differences between races:

1. Mouth structure

White people tend to have smaller teeth. Usually, they have crowded teeth and third molars that are impacted. They also usually have overbites.

Meanwhile, black people don’t usually exhibit crowded teeth. However, the upper teeth do tend to project outward. American Indians usually have teeth that are spaced well but show sclerosed dentition. When someone has sclerosed dentition, calcium deposits build up inside the tooth and thin out the root canal.

2. Palate

In whites, the palate is a parabolic shape. The ends of the palate flare outwards. However, blacks have a hyperbolic-shaped palate. There is no flaring at the ends of the shape. In American Indians, the palate has an elliptical shape with the palate shape angling to the back teeth.

3. Incisors

When determining the race of someone by their teeth, the shape of the incisors can be the biggest tell. In whites and blacks alike, the incisors are blade-form. However, American Indians have incisors that are shovel-shaped. The inner surface of the tooth is scooped or curved in appearance, much like a shovel.

Major Teeth Differences in Sex

Unlike the teeth differences between races, the differences between sexes are less obvious. According to some studies, there is a size difference between male and female teeth. However, those differences don’t apply to all teeth. They mostly apply to the incisors.

However, other studies show that few professionals can tell the difference between male and female teeth. In one study, experts and non-experts saw that images of 50 anterior oral regions of both sexes. Participants only made the right decision 50% of the time. According to the study, there is no way for the experts to tell the difference between sexes by their teeth.

Other people argue that the shape of a woman’s tooth is slightly different from the shape of a man’s tooth. Specifically, they say that women have rounded teeth and men have angular teeth. However, there isn’t much evidence to support this.

Interestingly enough, one of the biggest differences between male and female teeth could be the rate of decay. Women tend to have more decay than men. However, it has nothing to do with hygiene. Experts believe that female hormones impact the tooth decay. As your hormones change, they affect your saliva production. This can cause you to have less saliva, which means that bacteria does not wash off your teeth. As a result, the bacteria can build up and produce acid. That acid eats away at your teeth and causes decay.

Is one race or sex better than other?

Due to the increased chance of decay that comes with being a woman, men have “better” teeth than women. However, there is no other benefit that comes with having male or female teeth. They are similar enough that there is no obvious advantage to being either sex.

As far as race goes, there seems to be no advantage to one race over the other. If there is a difference, then it would be difficult to know about it. There is no simple way to look at which race has better teeth. For example, 51% of African American men have dental problems that go without treatment in the US. Only 28% of white men have untreated issues. However, it is likely that this is an economic issue and not anything related to tooth structure.

No matter which race or sex you are, there is one way to ensure that you have healthy teeth – good oral hygiene. You can prevent dental problems by practicing good oral hygiene and seeing a dentist regularly.
