The mystery of tooth composition1At 9: 00 on February 25th, a team of reporters from Xiaoshan Daily came to Xiaoshan Stomatological Hospital. Here, we will begin an oral journey.
We came to the fifth floor of dentistry to listen to Dr. Wan's lecture on oral health. Dr. Wan first introduced us to the basic structure of teeth and the growth process of teeth. Tell us that there are two pairs of teeth in a person's life, one is a deciduous tooth, the other is a permanent tooth, and a deciduous tooth has 20 teeth. After the age of six, permanent teeth began to grow and deciduous teeth gradually fell off.
How to protect teeth and prevent dental caries is the theme of this activity. According to the survey, dental caries has been listed by the World Health Organization as one of the three major prevention and treatment diseases after cardiovascular diseases and cancer. So, how can we protect our teeth and prevent dental caries? First, eat less sweets and eat more coarse grains, eggs and milk. When eating sugar, try to finish it within 1 minute, and don't leave it in your mouth. Second, we should develop good brushing habits. Brush your teeth 2-3 times a day, and you must brush your teeth in the morning and evening. Third, the method of brushing your teeth. There are two ways to brush your teeth, one is to brush in circles, and the other is to brush up from the gums, but both of them must be brushed from the inside of the teeth to the crown for 3 minutes. Teacher Wan said that tooth decay was actually not eaten by tooth worms, but eroded by bacteria growing in teeth.
Dental caries will also hinder the growth of permanent teeth, and may also make dentition grow unevenly, which will affect the appearance, so it is necessary to check teeth in time. Finally, Mr. Wan also told us how to correct our teeth and the best age to correct them.
The Stomatological Hospital also examined our little reporter's teeth for free. During the inspection, I also learned that many people have a misunderstanding that it doesn't matter if the child's teeth are decayed, but they will change their teeth anyway. Actually, it's not. Permanent teeth can't grow back when they are decayed. Therefore, we should vigorously promote the knowledge of dental health.
There are many mysteries in the world, and today I found one of them: the mystery of teeth! Let me tell you ...
This afternoon, the teacher arranged for the students in our composition class to charter a bus to Quanzhou to see a dentist and learn about dentistry. The students in the car were full of enthusiasm and chatted enthusiastically.
When I arrived at the dentist, a familiar strong hospital smell came to my nose. We hurried upstairs, entered the conference room and started the next lecture. The teacher introduced us a lot of little knowledge about teeth. What I remember most clearly is that there are only two pairs of teeth in a person's life-primary teeth and permanent teeth. I couldn't help touching my teeth in class to see if it was like this. When listening to the class, everyone was very serious, and the students spoke enthusiastically and actively. Speaking of six-year-old teeth, I pricked up my ears. The teacher said, "Count from the two teeth in the middle below. The sixth tooth is a six-year-old tooth. Six-year-old teeth won't grow again when they fall off, and so will the seventh tooth. " I quickly counted it and touched it for fear of missing a tooth. When I felt that my six-year-old teeth were intact, a stone hanging in my heart finally fell to the ground.
After class, everyone put on the doctor's clothes and took photos with the teacher. Everyone has a smile on his face. After taking photos, we went to check our teeth and experience the feeling of being a small dentist. The students waited anxiously in line for the dentist's experience. It's finally my turn. My little heart has been beating violently. After seeing my teeth, the doctor said that both my teeth should be pulled out. When I heard that I was going to have my teeth pulled out, I suddenly felt very uncomfortable.
This trip to the dentist taught me a lot about the mysteries of teeth. I secretly vowed to brush my teeth more and brush off all the moths in the future!
