Teeth are one of the main tools for everyone to chew food. They have their own shapes and uses.
When you open your mouth, the first thing you see is the front teeth standing like stars. A total of eight, all young people who like to steal the mirror. You only need to open your mouth a little to see their figure. The teeth referred to by words such as "bright eyes and white teeth", "smiling without showing teeth" and "red lips and white teeth" are them. Of course, they didn't just steal mirrors. They are shaped like sharp blades. They can cut almost all the food that enters their mouths in half, and they can bite off a large piece of food with a "click" and easily cut off a piece.
Next to the front teeth are canine teeth, and there are four * * *, which are the brothers of the front teeth, but they don't like to steal the limelight like front teeth. You have to open your mouth wide to see the whole picture. As the name implies, canine teeth are shaped like the front teeth of canine teeth, like the tip of a spear; Similar purpose, used to crush food. When the front teeth send the chopped food pieces, they will not hesitate to take over the job and cut the food into smaller pieces. After the close cooperation of the two brothers, the food began to digest easily.
Open your mouth wide and look in along your gums, and you will see two rows of chubby girls-grinding their teeth. Much bigger than the first two, cute and fat. But don't underestimate them just because they are fat-they are the main force in chewing food. Only when they chew the broken food of front teeth and canine teeth several times can you swallow it and digest it in your stomach. And the harder they work, the easier their stomachs will be.
Behind the molars, in the dark corner, there are several young gentlemen-wisdom teeth. Compared with the previous ones, they are a little less useful, but they are only used to help grind teeth and help chew. They are not only of little use, but also have a poor appearance. They are the only group of teeth with incorrect orientation, and they always tend to lean towards molars.
Although the shapes and uses of these teeth are different, if one tooth is missing or broken, it will not only affect the appearance, but also affect the stability and even health of the whole gum. A tooth is like a big family. If all the people in the family are healthy, work hard and unite as one, the family will surely prosper.
You must have been pulled out by the dentist. I've been there. I thought the dentist's tooth extraction was painless, but it backfired. I pulled it out once and never dared to go to the hospital again.
This time, the fangs in my lower row have been loose for half a month, but they have not fallen off. Tonight, my father said that we should look at the condition of this tooth. If you grow new teeth, the consequences will be unimaginable. Looking at my father's serious face, I had to take my hand covering my mouth away. I saw my father put a finger in my mouth and only heard a click. With this severe pain, a drop of blood came out of my mouth, and my mouth was full of blood. I cried. My mother rushed from the kitchen and covered my mouth with a towel. The bleeding gradually stopped. I thought dad couldn't pull it out. The indomitable father will continue his plan, which scares me to death. Dad had to go upstairs. Looking at this falling tooth, I asked my mother to pull it out for me. My mother was scared. I have no choice but to do it myself. When I exert a little force, my teeth will fall out. Either the doctor or my father pulled this out before. Sometimes, when new teeth come out, old teeth have to make way and jump down at dinner. As you can imagine, all the new teeth are inward, which is really ugly. Mom is very happy, because she has grown so big, I pulled out my own tooth, and it is the tenth tooth, although with the help of my father.
Believe me, from now on, I will definitely pull out my own teeth.
I have been changing my teeth since I was in primary school. First, the front teeth in the middle make me "toothless". I always miss pinyin and can't read it correctly.
Now, I have changed my teeth on both sides again. I was chewing rice that day and thought it was strange to have a tooth on the right side of my mouth, so I asked my father to show it to me. Dad said, "This tooth needs to be changed." He told me not to touch it and told me, "I hope it fell by itself."
But is it so obedient to let it fall by itself? According to my previous experience of changing teeth, this process is very difficult! No, it's been loose for almost two weeks, and it's been shaking!
I have a rickety tooth in my mouth, and I feel very uncomfortable! Every time I eat, I try to avoid loose teeth and always switch to the left tooth carefully to chew. But I'm greedy and my mouth is always full. I accidentally touched it while eating, which made me want to cry.
I really hate this tooth. It's getting looser and looser, but it won't fall off. I thought: Why does it love me so much?
I can't take it anymore! I must have this tooth pulled out. I stood in front of the mirror and looked at this tooth, trying to pull it out myself. I held out two fingers and caught it. As soon as I tried hard, the pain stopped. This is even worse. Not only did he not come out, but he still had blood in his mouth. I have to go to the bathroom to rinse my mouth and rinse my mouth. Haha, this tooth fell out.
I'm glad this tooth finally fell out. However, it feels strange to lose a tooth, as if something is missing from your mouth.
Last week, our class listened to a lecture on "Healthy Through Train-Prevention and Treatment of Children's Common Dental Diseases" in the Star Theater, which made me know a lot about tooth protection and benefited a lot.
Teeth are an important organ for human survival, a small helper for us to chew food, and a major component of chewing organs, which is closely related to your language, appearance and health. If you don't care at all and don't protect yourself, you will be very painful when you know your mistake. So, how can we protect it correctly and effectively and make it work effectively?
First of all, master the correct way for children to brush their teeth. First of all, the doctor told us the correct way to brush your teeth: the upper teeth are brushed from top to bottom, the toothbrush is at a 45-degree angle with the tooth surface, and the lower teeth are brushed from bottom to top at a 45-degree angle. The upper teeth are brushed from top to bottom, and the lower part is opposite to the upper part. More importantly, the toothbrush should be pressed on the occlusal surface and brushed back and forth. If the method is wrong, it will affect your tooth growth and health.
Second, we should form good habits. The doctor also told us that good living habits are also very important, for example, sticking out your tongue and biting your tongue will form an open tooth deformity; Tongue licking your teeth will make you look "open your mouth and show your teeth"; Biting your fingers and pens will make your teeth close. Failure to form a good habit of loving your teeth will have a great influence on your behavior.
Third, dental caries should be treated in time and checked regularly. The doctor also told us that once we feel uncomfortable with our mouth, we should go to the hospital immediately for examination and timely treatment. If not treated in time, it will not only affect your health, but also lead to voice leakage and unnecessary embarrassment.
Finally, the doctor invited several students to demonstrate brushing, which made me know more about the correct method of brushing.
Tell all students: we must take care of our friends: teeth. Avoid unnecessary harm!
There is a kind of trouble bothering my mother. As soon as I picked up my toothbrush in the morning, my mother's nagging came. Brush your teeth carefully! When I really brush hard, my mother gets bored again and will hurt my teeth! Alas, how to brush your teeth without hurting them and keep them clean and tidy? A small reporter activity in Xiaoshan Daily solved my mother's troubles.
In this activity, the doctor of Xiaoshan Stomatological Hospital taught our little reporter how to care for our teeth. Mother's biggest headache is brushing her teeth. The doctor said, "Brush your teeth up and down so as to clean up the residue between your teeth." Horizontal brush can't achieve this effect. It takes three minutes to brush your teeth, so that your teeth can be cleaner. "My mother has been worried that my new teeth won't grow. For this question, the doctor told us that the tooth changing period refers to the age of six to 12, the growth period of deciduous teeth is six months to six years old, there are 20 deciduous teeth, and a six-year-old tooth will grow at the age of six. Doctors also say that teeth can get sick, such as calculus, bleeding from brushing teeth, swollen gums, bad breath and so on. There is a kind of dental disease caused by tooth decay. There are several levels of tooth decay, one is shallow and the other is moderate. Look at it in time when it is moderately decomposed, and don't wait until it is deeply decomposed. Because if you don't see the decayed teeth in time, even the roots will rot. There is only one black hole left, and no new teeth can grow. I shudder at the thought that opening my mouth will expose the black hole. Fortunately, the doctor told us at once that the way to make our teeth strong is to eat more vegetables, fruits, milk and eggs. The most interesting thing in this class is about how to deal with a tooth after it falls off: once the tooth falls off carelessly, it should be soaked in milk immediately, or put under an adult's tongue, and then see a doctor immediately. The doctor has a way to get this "wandering tadpole" back to its original position and grow sturdily as before. This is amazing. One of my classmates accidentally knocked out a new tooth while playing and went to the hospital for treatment every week. According to the teacher, it may take treatment until the age of eighteen! If he had known this information earlier, the teeth he had protected in the first place would not have been in so much trouble.
Small teeth are learned. This activity not only made me realize the importance of protecting my teeth, but also let me master the scientific methods of maintaining my teeth. Most importantly, when I go home and share my lessons with my mother, my mother doesn't have to worry about my teeth anymore!
Xiao Ming is a child who likes snacks very much, and there are mountains of snacks at home. For example, when you are hungry, it is convenient and quick to sit there and watch TV and reach for snacks. Do you think there are many snacks in his house?
Once, Xiao Ming was still eating snacks while watching TV. His mother really couldn't stand his bad habits and asked Xiaoming to brush his teeth. Xiao Ming ran to the bathroom to pick up the cup, took a glass of water, washed the water in his mouth at random, and ran back to the TV to get several bags of snacks. Mother can only smile at him like this.
Late at night, Xiao Ming has fallen asleep. At this moment, a voice came from Xiao Ming's mouth, bang! Bang! Bang! After a while, Xiao Ming opened his mouth and said something in his sleep: "Ouch! I have a toothache! My teeth are hurting! " In fact, there are many bugs biting his teeth in his mouth, which makes his teeth strange. Others said that he was a "tooth monster", hence the name. ) It's been like this for several nights in a row.
Xiaoming's tooth was finally bitten by a bug, leaving only a small one. He didn't want to die, so he was ready to run away. So the tongue advised the tooth not to run away, and the owner would be very sad, but the tooth did not agree. It said, "He killed me. I want him to taste the inconvenience and pain of toothless!" " "As soon as the words were finished, the teeth ran out of Xiao Ming's mouth one by one. The next day, Xiao Ming found that nothing could be chewed while eating, and the food went directly into the esophagus. So he touched it with his hand and found that his teeth were gone. He immediately ran to the bathroom to look in the mirror and found that there were only gums in his mouth and no teeth. He let out a cry and fainted.
When he woke up, he clearly knew that it was because he loved snacks. So he secretly made up his mind that he could only eat snacks once a day at most. However, this diet plan cannot be carried out immediately. Gradually reduce the number of snacks, so that the number of times you add food will naturally come back.
Xiao Ming insisted on eating three packs of snacks every day since then, and then he ate less snacks and insisted on brushing his teeth every morning and evening. These good habits are known to the teeth, and they are very happy that their master has become like this and returned to the gums.
Xiao Ming went to the bathroom in the morning and found that all his teeth had grown back, jumping and jumping with joy. Xiao Ming's parents saw all this and smiled happily, showing their white teeth.
The teeth returned to Xiao Ming's mouth, but there were no teeth on a gum. "Sister, brothers, pull me up!" It turned out that a tooth was missing in a corner of the bathroom. It turns out that it is too small to be bitten by insects. The other teeth left first, leaving it alone outside. In this way, with everyone's help, it returned to the gums safely.
Children should remember to eat less sugar and brush their teeth frequently in the future! Otherwise, it will be just like Xiaoming!
Every time I eat these days, my teeth always don't listen to me. It's terrible!
That day, I was eating hot pot with my parents at home. I picked up a tempting piece of beef and put it in my mouth, intending to enjoy it to the fullest! Ouch! One of my big teeth really hurts to chew, so I have to chew on the other side. Ouch! I can't chew. I swallowed the whole piece of beef like a toothless guy.
It has been like this for several days in a row, but it makes me feel terrible and hurt. I don't know what happened. Did my teeth "strike" by secretly not brushing my teeth in the morning? Yesterday, my teeth finally told me the truth-I'm going to change my teeth.
I had a toothache all day yesterday, and I could only chew with my front teeth like a rabbit! This tastes bad. I tried to put my tongue against the tooth that was about to fall out. At the top ..... Finally, my teeth shook badly. But I can't eat more.
The next day, I continued to work-gritting my teeth all morning. Haha, many things happen. That tooth is finally teetering!
Have lunch. Eat ham, sausage, corn and fried green beans today. While eating, I was wondering what game I would play with you later. "Ah-oh-"A scream of "making the gods cry" jumped out of my throat. It turned out that I accidentally bit the green beans with my "bad teeth", and my mouth was really miserable!
After coming home from school, I used the break time to shake my "bad tooth" by hand, trying to make it fall off so that I could end this "miserable" life early. My father is a doctor. He said to me, "As long as you work harder, bite your teeth and break it off with your hands, it won't hurt." "Knock out your teeth! Really? Isn't it more painful to break? " "No, it just hurts a little." Dad replied.
I wanted to completely relieve my toothache, but I was afraid it would hurt more when I pulled out my tooth, so I stood by the window and thought for a long time. Finally, I got up the courage to say to my father, "ok, but I dare not pull it out myself." Please help me pull it out! " "Say that finish this sentence I have a feeling of throwing caution to the wind. Dad told me to open my mouth and raise my head. I closed my eyes in fear ... "Bang-"My teeth fell on the table. Hey, it doesn't really hurt! I looked at the "bad tooth" that killed me not long ago and wanted to swallow it!
Ah! Damn bad teeth, you finally "retired"! I have been looking forward to this moment for dozens of hours!
Tooth Grade 5 Composition 8 Dear Little Master:
Hello!
I'm your tooth, the tooth that specializes in eating.
I know I am humble now, but I have eaten delicacies and all kinds of mouth-watering food. Thank you very much
Whenever I go abroad to play, I eat delicious food and drink all kinds of drinks, as if I have eaten all the delicious food from all over the world, which makes me feel happy!
But in recent years, you like sweets and ice cream more and more. Although you are full, my brothers and sisters and I are more and more worried about you, and the power of tooth decay is growing. Although I love eating, even a little greedy, I never want you to replace our brothers and sisters with Kouga after a big tooth decay!
One day, moths drilled a big black hole in me, which made me ugly and even painful; You cried so much that everyone couldn't sleep all night. The next day, my mother took you to the doctor, and I was pulled out by the dentist with pliers. At this time, you are crying to death.
At that moment, I found an aperture on my head, and I found that I became an angel.
Goodbye! Little master! I hope that after learning the lesson, you can form the good habit of washing your hands before meals and brushing your teeth and gargling after meals, so that my brothers and sisters will not come to see me in heaven too early!
Bless you! My dear little master!
Love your teeth
Your respect/sincerity
Once upon a time, there was a little boy who didn't like brushing his teeth. One of his teeth was blackened by moths. Teeth become black inside and white outside, which can be said to be black and white. So the little boy pulled it out. Tooth said goodbye to his master sadly, packed his luggage and prepared to start an adventure.
Walking, this tooth goes into the forest, and all the creatures here will attack me, so I must be careful. Tooth thought, Tooth climbed a tree, wanted to drink dew and eat some fruit. In the process of climbing again, my teeth met a caterpillar. Ah! I was so scared that Daya almost fainted. When Daya saw a caterpillar, it was like a person saw a train. Caterpillar is hostile to teeth and wants to eat them at any time. Tooth immediately detoured, but the caterpillar followed. A sparrow saw it and flew to eat the caterpillar. Poor caterpillar! The sparrow saw that the teeth were white outside and black inside, and exclaimed: Wow! This must be a gem. Take it back to my new home and show it off to my neighbors!
So the sparrow put its teeth on the edge of its nest and fixed them with mud and saliva. It's beautiful. His teeth are fixed and can't move, so he didn't come out with all his strength.
When the neighbors of the sparrow saw it, they all praised the beauty of the gem. Sparrows proudly looked up and smiled, and the next second they couldn't laugh. A poisonous snake has taken a fancy to these delicious sparrows, and the other sparrows are scared to fly back to their nests to look after their children. The poisonous snake not only swallowed the sparrow directly, but also bit the sparrow's egg. The poisonous snake also saw it. The poisonous snake made three branches into a circle with weeds, and then fixed its teeth on the middle branch with mud. Haha, it's done. The poisonous snake put the crown on its head. The poisonous snake looked at other animals and smiled proudly at the crown on its head.
A snake keeper saw this colorful snake and thought it could be sold for a lot of money. He walked carefully behind the snake and hacked it to death with a jungle machete. The snake keeper saw the tooth on the head of the snake and said, what, haha, there is actually a tooth of us humans. I just threw this tooth into the river.
Tooth went all the way along Shui Piao to a picturesque place. Tooth's mouth opened wide and said, Wow, it's beautiful. Fang Ya settled here and lived a happy life.
I am a 10-year-old tooth. I live in the mouth of a boy with glasses. Although I am young, I have tasted the joys and sorrows of the world.
ferment
My master likes jiaozi best. When eating jiaozi, he often dipped in vinegar, which is his favorite, so I often deal with vinegar.
sweet food
My master likes sweet things, too. When he eats carambola, he will pour sugar on it and eat it. Sometimes he puts sugar in his water. My brothers were attacked by aphids because he put too much.
difficult
My host hates suffering, especially when he is sick and takes medicine, and he doesn't want to eat it. But for the sake of young master's illness, I can only be a hero once (that is, take medicine)
fragrant
Young master likes spicy food. He is eating mutton skewers, noodles and other foods, and likes to eat a lot of Chili powder. Every time, my whole body is numb with hot pepper, but the young master is very smart and finds that I am covered with Chili powder, so he will pick up his toothbrush like a fireman and bathe me with fragrant toothpaste.
This is my master and this is me.
