Seeing this, Bai Xuan's gaze could not help but froze slightly.

Then continue to search for information.

Teeth replacement is a physiological need of human digestion.

The older the teeth, the larger the gums and the increased distance between the teeth.

And there will be gaps, which cannot be sucked out when chewing.

At this time, more teeth with better quality are needed to replace them, and permanent teeth with better quality and stronger can accompany people's lives.

"So changing teeth is a good thing?"

"But I've had my teeth changed once, will I change my teeth again when I'm an adult?"

With such doubts, Bai Xuan continued to search.

It didn't take long to find out.

Under normal circumstances, teeth will not change in adulthood, but teeth may erupt.

After the age of 18, the tooth replacement has basically been completed, but wisdom teeth may grow out at this time.

The rule of teeth replacement is that deciduous teeth gradually erupt from 6 months to 2 and a half years old, and there are a total of 20 deciduous teeth.

Around the age of 6 is the alternating period of deciduous and permanent teeth. At this time, the deciduous teeth gradually begin to fall out, and the permanent teeth erupt one after another. By the age of 13, all deciduous teeth are replaced by permanent teeth, with a total of 28-32 teeth.

Therefore, the age of tooth replacement is between 6 and 13 years old, and there is generally no tooth replacement at 18 years old.

"Wisdom teeth?"

Keep searching and get the answer.

Wisdom teeth are called third permanent molars in medicine, and usually begin to erupt at the age of 18-20.

At this time, people's psychological and physical development is close to maturity, which is usually regarded as a symbol of the coming of wisdom, so it is called wisdom teeth.

Wisdom teeth are a normal physiological manifestation.

There are two sets of teeth in the process of human growth, namely deciduous teeth and permanent teeth.

In the primitive stage, due to the wear and tear of rough food, the height and width of the teeth are continuously reduced, and the rear teeth move forward. The third molars usually erupt normally around the age of 16.

In the process of evolution, the food eaten by human beings has become softer and finer, and it no longer requires excessive bite force to chew food.

As a result, the volume of the jaw bone in the oral cavity has evolved smaller and smaller, resulting in smaller and smaller spaces for teeth to erupt.

The eruption time of the third molars is also continuously delayed, and generally erupts around adulthood (18-30 years old). It is generally believed that this stage is the peak period of intellectual development, so it is called wisdom teeth.

"That is to say, because of the effect of Yijin and marrow washing, my intelligence has begun to develop?"

"correct."

"In the introduction to the effect of Yijinxiexiui, there are the four words Kedengzhengguo."

"Zhengguo in the Buddhist scriptures means attaining the Tao through cultivation and attaining a righteous fruit, but there are no immortals, Buddhas, ghosts and gods in the real world."

"So the word Zhengguo probably represents a kind of wisdom."

"The attainment of the fruit also means that the intelligence has been enhanced."

"So I'm about to grow wisdom teeth?"

Although wisdom teeth seem to represent wisdom, but Bai Xuan did not know where to see it, wisdom teeth do not seem to be a good thing.

Then continue to search for information.

get an answer.

The function of wisdom teeth is to grind the food that the front teeth have cut into small pieces when chewing food, and grind it into chyme, which is convenient for digestion and absorption.

However, wisdom teeth are also prone to damage to front teeth, wisdom tooth pericoronitis, and cysts.

Seeing this, Bai Xuan was relieved.

I have not only completed Yi Jin and Xie marrow, but also practiced Hua Jin, able to reach the four tips.

It is too simple to let wisdom teeth grow normally without endangering oral health.

There is no harm if wisdom teeth erupt.

Then growing wisdom teeth becomes a good thing.

Because wisdom teeth are not useless.

Wisdom teeth can play a grinding role when chewing food, grinding the food that has been cut into small pieces by the front teeth, and grinding it into chyme, which is convenient for digestion and absorption.

That being the case,

Doesn't growing wisdom teeth strengthen one's own digestion ability in disguise?

The answer is so obvious.

Therefore, Bai Xuan was relieved and continued to practice martial arts.

With the powerful effect of changing tendons and washing the marrow, I can completely improve the three skills of Wudang original Taijiquan, Yang style Taijiquan, and three-swing and three-swing Taiji pushing hands to LV3 before school starts.

As for filling in the school and choosing a major, how much time can I spend on things that have already been decided?

in this way,

Time passed quickly.

at the same time,

In the Wudang Mountains,

Yang Qingyun was sitting in front of Zhang Shiming, took a sip of tea and said:

"Master Daoist, how are you thinking?"

Looking at Yang Qingyun's appearance that is bound to win, Zhang Shiming also looked serious, and said in a deep voice:

"Lady Qingyun, are you sure you didn't lie to me?"

"The person you mentioned really has the hope of breaking the limits of the human body and opening up the realm of martial arts above Baodan sitting on the hips?"

"You know, this is something that Mitutoyo has never done!"

Seeing Zhang Shiming's appearance, Yang Qingyun immediately said confidently and seriously:

"Society is constantly developing, science is constantly developing, and martial arts is also constantly developing."

"Sanfeng Zhenren is indeed talented, and he is incomparable throughout the ages."

"But the era he lived in was so backward that there were no conditions to break the limits of the human body."

"But times are different now!"
