"Auntie, what is tooth replacement?" Su Xueyan took a sip of Wensi tofu soup in her small hand, smacked her lips and asked.

Well, this soup made by Sister Ah is really delicious, take another sip.

Su Xuanhe glanced at the girl who had become a foodie with a complaint: He, who is a brother, now has a broken tooth and a mouth full of blood, such a tragic experience, this girl only thinks about eating!

Seeing his son's aggrieved little expression, Yang comforted: "It's okay, everyone has to lose this baby tooth, wait for a year and a half, and the remaining permanent teeth will slowly grow out, so there will be no such tooth leakage." ”

Originally, Yang thought that his son would always be a little relieved if he was so comforted, but he never thought that Su Xuanhe would almost collapse and shout: "What? Another year and a half?! ”

He completely forgot that he was still in a state of "missing teeth", and the front teeth were one of the most affected exhalation teeth, and as a result, in just a few words, he was leaking when he said it, and even his pronunciation was affected.

"Hahaha......" Su Qingluan said she was smiling happily.

"You!" Su Xuanhe looked at his unscrupulous sister angrily, and her little face turned black and red.

"Ahem, don't laugh, big girl, who didn't come here like this." Su Guangfu coughed dryly, trying to find a step for his son, who already felt embarrassed.

As a result, the little girl who was sucking and drinking tofu soup on the side heard this, and was so shocked that she almost dropped the bowl: "Does everyone want to change their teeth?" ”

After getting the nod of affirmation from her father and sister, the little girl didn't care about drinking tofu soup, so she hurriedly grabbed Su Qingluan's sleeve and asked, "Sister, my front teeth will also fall out like my brother's?" ”

"It's not just the front teeth," Su Qingluan gave the two children a science popularization on a case-by-case basis, "all the teeth will fall out in the next period of time, and then ......"

Before the rest of the words could be spoken, Su Qingluan heard a low sob, and then-

"Wow...... I'm going to be toothless!! ”

"Woo woo woo...... Sanya should not be toothless!! ”

The two little ones suddenly burst into tears.

Su Qingluan hurriedly shouted: "Didn't you say that baby teeth will grow out after falling out!" "Don't start crying halfway through it, and didn't A-Niang tell them just now?

As a result, the two children focused on places like "it takes a year and a half to change their teeth", and they didn't pay attention to other content at all.

"Will it grow?" Su Xuanhe looked at Su Qingluan cautiously.

Although Su Xueyan didn't say anything, she also raised her head pitifully and looked over.

Su Qingluan bared her teeth, pointed at herself, and looked at Su Guangfu and her family: "Look at me, and then look at my father, no one is missing a tooth, right?" "There may even be a few more.

The two children looked at Su Qingluan first, and then looked at their father.

In order to comfort the children, Su Guangfu and Yang also opened their mouths slightly to the two children when they looked over, so that they could rest assured.

The two children finally calmed down and stopped crying.

However, before he had time to calm down for a few breaths, Su Xuanhe became nervous again: "Can ...... But many of the grandmothers in the village have no teeth! ”

"That's because they're too old." Yang comforted.

"Old?" Children's curiosity can't be stopped, Su Xueyan turned her head and asked A-Niang, "Why do you have no teeth when you are older?" ”

This made Yang embarrassed, she only knew that her teeth would loosen and fall out when she was old, but where did she know the reason.

Just as Yang was thinking about finding a random reason, he saw the eldest daughter touch the top of the younger daughter's head, and said softly: "Because of age, the gums will recede, and the gums that originally tightly clamped the root of the teeth will not be able to fix the teeth, and the teeth will fall out." ”

"So, we won't be toothless for a while?" Su Xueyan asked expectantly.

"Yes, it's too early for you to lose your teeth," Su Qingluan looked at his younger brother and sister with a smile, "But from now on, as long as you rinse your mouth with water every day and brush your teeth with tooth powder, you may not lose your teeth when you are old." ”

In modern times, even the elderly, if carefully maintained, there are many people who have not yet lost their teeth.

Although the medical conditions in ancient times were limited and not as good as those in modern times, Su Qingluan believes that there are not so many sugary drinks now, so that the two little ones can eat less sugary dim sum cakes and more healthy and tooth-fixing foods, which may not be able to reach the level of modern care.

Under the joint appeasement of Su Guangfu, Yang and Su Qingluan, the two children finally stopped crying, and finally understood that everyone would experience the matter of "changing teeth", and it was not such a terrible thing.

However, the little girl still pulled Su Qingluan's sleeve a little worriedly: "Sister, does it hurt to change your teeth?" ”

"You ask if your brother hurts?"

As he spoke, he got up and said to his father: "I'll go get some salt water and rinse my brother's mouth, my mouth is full of blood, and it is strange to eat any food." ”

After Su Qingluan left, Su Xueyan turned around and pulled Su Xuanhe's sleeve again: "Brother, does it hurt?" ”

Su Xuanhe blinked.

Just now, he was too shocked because of the "tooth is gone", but he ignored the others, and now think about it-

"Well, it doesn't hurt much, but when I was eating vegetables, the tooth suddenly fell out on its own."

Su Xueyan heard her brother's "assurance" like this, and breathed a sigh of relief a little with relief.

Yang said with a smile next to him: "Changing teeth usually doesn't hurt much, but Erzhuang has to eat more carefully recently, don't swallow the lost teeth." ”

“…… What will happen if you swallow it......" Su Xuanhe asked a little cautiously.

Yang: "......" Why did these two children ask these questions today that she couldn't answer.

This time, it was Su Qingluan who broke the siege.

"It won't be good," with a gentle "bang", a bowl of light salt water was brought to Su Xuanhe's eyes, Su Qingluan sat back and picked up a piece of bean cake, "Baby teeth can't be digested, how to get in and how to get out." ”

Of course, it would be inaccurate to say that it is completely indigestible, but she can't explain to an ancient child what calcium carbonate dissolves in slightly acidic conditions, right?

It's a ghost animal when you think about it.

Yang couldn't help but laugh when he heard his eldest daughter's words, and then turned around and asked his son, "Where did the tooth you just lost go?" ”

Su Qingluan teased: "You won't really swallow it, right?" ”

Su Xuanhe shook his head again and again, lowered his head and looked under the table, and then picked up the front tooth on the ground next to the leg of the stool and held it on the palm of his hand: "A-Niang, here you are." ”

"This time you lost your upper tooth, and when you go to the yard later, you see where you like, bury the tooth a little deeper." Yang said to his son with a smile.

"Why bury it?" This is what Su Xuanhe asked.

"And what if it's the lower teeth?" This was asked by Su Qingluan.

Su Qingluan had only heard the custom of throwing the fallen baby teeth on the roof, and it was the first time he had heard the phrase of being buried in the ground, so it was a little new.
