Why Japanese have bad teeth... Options

[aZnRiCeChiQ]

The problem is that while the jaw has decreased in size for Japanese women over the past 2,000 years (I'll try to update with an actual study I saw), the teeth have remained the same size, and it's particularly a problem for the so called "Mongoloids" because they have wisdom teeth almost always. This leads to overcrowding of teeth and thus the stereotypical crooked teeth that is for Japanese women the badge of shame for all Asians.

Well, the Yayoi seems to come from mainly Korea, and replaced the Jomon in Japan within the last 2,000 years. Within that time period, there seems to have been some noticeable pedamorphic tendencies in Japanese females. Compared to Korean females, Japanese females are more child-like, with weaker jaws.

The causes of reduced jaws is a general gracilization trend in post ice age humans, and there could be a number of causes, such as sexual selection, adapting to eat mush from agricultural products instead of fiberous and meaty stuff of hunter-gatherers, getting smaller for the warmer weather. The problem is particularly a problem for Japanese women because they are very pedamorphic, going from big-jawed Mongolian types to lil' girl types in a matter of millenia.

Below are qoutes from an article address this problem:

"Evolving to Eat Mush": How Meat Changed Our Bodies
http://news.nationalgeographic.com/news/20...human_diet.html

"Our taste for meat has also led us into some trouble—our teeth are too big for our downsized jaws and most of us need dental work."

...

"Tool-use no doubt helped early humans in butchering their dinners. But there is evidence that the advance to cooking and using knives and forks is leading to crooked teeth and facial dwarfing in humans.

Today it's relatively rare for someone to have perfectly straight teeth (without having been to the orthodontist). Our wisdom teeth don't have room to fit in the jaw and sometimes don't form at all, and the propensity to develop gum disease is on the increase.

"Virtually any mammalian jaw in the wild that you look at will be a perfect occlusion—a very nice Hollywood-style dentition," said Peter Lucas, the author of Dental Functional Morphology and a visiting professor at George Washington University in Washington, D.C. "But when it comes to humans, the ideal occlusion [the way teeth fit together] is virtually never seen. It's really the only body part that regularly needs attention and surgery."

Lucas argues that the mechanical process of chewing, combined with the physical properties of foods in the diet, will drive tooth, jaw, and body size, particularly in human evolution.

Essentially, by cooking our food, thereby making it softer, we no longer need teeth big enough to chow down on really tough particles. By using knives and forks to cut food into smaller pieces, we no longer need a large enough jaw to cram in big hunks of food.

"We're evolving to eat mush," said Bernard Wood, a paleoanthropologist at George Washington University."

Someone asked me to post this.

It's not a flame topic or an insult. It's based on an anthropological article.

not really just that but also ther alignment of teeth are out of order or the teeth are not at equal lengths.. my japanese friend works as a nurse at a healthboard in japan and says sometimes japanese people come in for jaw implants.. sounds painful...

I thought it was because the food they eat isn't as solid as the food in other countries, so there gums are not as strong.

well technically from health stats. korean youth are skinnier while japanese older generations are skinnier than our korean older generations. they say its from the popularity of fast foods more for japanese youth more than for korean youth.

however there is a variety of japanese people. not allll of them are like this.

Those Japanese girls are too skinny no doubt about it.

However since atleast the neolithic times east asian populations have been evolving towards a smaller jaw.
There are many Chinese who have too many teeth for their smaller jaw thus creating dental problems and require brasses.

[toki]

my experience going to japan is that still a good number of the youth is a bit chubbier nowadays due to the influx of fast foods. there are fast foods in china and korea as well. but i think the japanese tend to consume more. in my experience and also stats. korean youth is skinnier.

[Suijen]

From what I see, a lot of Japanese chicks have not-so-organized teeth and stocky legs.
