What are Wisdom Teeth?
Wisdom teeth, also known as third molars, are the last set of teeth to emerge in the back of the mouth. They typically appear during early adulthood, around the ages of 17 to 25. Most people have four wisdom teeth, one in each corner of the mouth, located at the very back of the upper and lower jaws. However, some individuals may have fewer or no wisdom teeth at all.
The Japanese Name for Wisdom Teeth: “Oyashirazu”
In Japan, wisdom teeth are called “Oyashirazu” (親知らず), which translates to “unknown to parents.” There are two main theories behind this unique name:
- Wisdom teeth emerge without the parents’ knowledge
As wisdom teeth typically appear when a person is in their late teens or early twenties, they often develop after the individual has left their parents’ home and started living independently. - Wisdom teeth appear when a person has gained their parents’ wisdom
The age at which wisdom teeth emerge is considered to be when an individual has acquired the wisdom and life experiences of their parents.
Wisdom Teeth in Other Languages
The term “wisdom teeth” is widely used in English-speaking countries. This name stems from the idea that these teeth emerge at an age when a person has gained greater wisdom and maturity. In dental terminology, wisdom teeth are referred to as “third molars,” as they are the third set of molars to develop.
In German, wisdom teeth are called “Weisheitszähne,” while in French, they are known as “dents de sagesse.” Both of these terms translate to “teeth of wisdom,” sharing a similar etymology to the English name.
Conclusion
Wisdom teeth, or third molars, are the last set of teeth to emerge in early adulthood. In Japan, they are known as “Oyashirazu,” which translates to “unknown to parents,” referring to the idea that they appear when a person has gained independence or acquired their parents’ wisdom. While the Japanese name is unique, the concept of wisdom teeth is universal, with similar names existing in other languages. As wisdom teeth can vary in their development and positioning, regular dental check-ups are essential to monitor their growth and address any potential issues.
