大家好，我是石头团团呀！我很遗憾，智齿重返人类口腔的行动失败了。
Hello everyone, I am stone Tonton. I'm sorry to say that the return of wisdom teeth to the human mouth has failed.
总想回到人类口腔的智齿，却并不太在意。
But wisdom teeth, who always want to go back to human mouth, don't really care.
智齿说：“如果我回到口腔，人类也不会允许我留在那里。人类不需要我。”
The wisdom teeth say, “If I go back to the mouth, humans won’t allow me to stay there. Humans don't need me.”
人类喜欢吃烤肉，烤熟的肉比生肉更香、更软，更容易咬断。人类不需要智齿。
Humans love to eat grilled meat,which is more flavorful, softer, and easier to bite off than raw meat. Humans don’t need wisdom teeth.
现在，人类吃烤肉，咀嚼的次数变少了。
Nowadays, humans eat grilled meat and chew less.
用来咬断食物的门齿变窄了；The incisors used to break food become narrower.
用来撕咬食物的犬齿变短了；The canine teeth used to bite food are shorter.
用来研磨食物的臼齿变小了；The molars used to grind food get smaller.
牙齿的大小逐渐一致，排列也逐渐整齐。The teeth are gradually the same size and aligned.
颌骨也变小了，智齿的位置就越来越小。
As the jawbone becomes smaller, the wisdom teeth become smaller and smaller.
如果智齿硬挤在齿列上，有的牙齿就被挤歪了。
If the wisdom teeth are hard pressed against the dentition, some teeth are squeezed crooked.
人类的齿列就很容易变得不整齐。
Human dentition can easily become irregular.
我的智齿有点懊丧地说：“唉，所以，人类不需要我，人类需要我离开口腔。”
My wisdom teeth say, a bit chagrined, "Well, so humans don’t need me, humans need me to leave the mouth."
