Evidence shows that the ancients knew how to use toothpicks to

The discovery of the use of toothpicks for this ancient human oral hygiene was published by Swiss scientists.

Recent researchers have explained the reason why the teeth of the first ancient people (people with relatives and modern humans) had big holes and changed quite a lot. That's because the ancient people used toothpicks to clean their teeth.

This conclusion was drawn after archaeologists conducted fossil studies of the first ancient human species in the Dmanisi region (Republic of Georgia), dating back about 1.8 million years. This fossil consists of four sets of jaws (upper or lower) of both youth, the elderly and some other families - found in the above Dmanisi area.

Part of the huge gap between teeth revealed the habit of using toothpicks of the ancient people

Paleontologist Ann Margvelashvili from the Research Institute and Museum of Anthropology Zurich (Switzerland) said: "We have studied the upper teeth of fossils because they are often better preserved. compared to other parts ". The results show that it is the abuse of toothpicks that causes the ancient human teeth to be transformed and have a big gap.

Scratches are found in the root of the tooth that reveal the habit of flossing too many times, leading to swelling in the jaw and infection. This partly indicates how ancient humans were eating and surviving.

However, the collected functions have many big differences. Some people believe that this is merely a difference between the two sexes in the same species. The other group asserted that this disparity comes from the incompatibility between different species in the family.

To resolve this concern, scientists analyzed the alterations in the jaw bone of hunters and gatherers in Australia, Greenland, then contrasted with the teeth and jaws of the ancient group of people found in Dmanisi.

The results show that the difference of the set of functions found in Dmanisi simply comes from the diversity of individuals in the same species. In theory, teeth can wear away in different ways, leading to the reshaping of the jaw's features, including how to arrange teeth, length and jaw angle .

Experts discovered that, in a set of jaws found in Dmanisi, almost all of the teeth were worn, leaving only one fang. Researchers predict that in order to survive when there are no teeth left to eat, they must definitely use a specialized tool to soften food before 'enjoying' it.
