Precautions for changing teeth for children in large classes

Tips for changing teeth for children in large classes 1. What is the knowledge of changing teeth for children?

The order of children's tooth changing period is the first permanent molar, also called the sixth molar, which grows immediately after the last deciduous molar at the age of 6. Earlier or at the same time as the lower central incisor, the lower central incisor (the lower two incisors) fell off at the age of 6, the lower central incisor grew out, the upper central incisor (the upper two incisors) fell off at the age of 7-8, the upper central incisor grew out, the lower central incisor fell off and the lower central incisor grew out. 8-9-year-old deciduous upper incisors fall off and grow permanent upper incisors; At the age of 9- 12, the first and second deciduous molars fell off, and the first and second pairs of canines grew. 10 ~ 12 years old, deciduous teeth fall off and permanent teeth grow out.

There is a certain time and order for deciduous teeth to stay or fall off prematurely. The deciduous teeth that should fall off without falling off are called retention, and the consequence is often that the permanent teeth cannot erupt in the normal position. Tooth loss usually begins with the next two incisors, and then the last two incisors.

The most common is that the lower front permanent teeth grow on the inner side of deciduous teeth, and the upper front permanent teeth grow on the outer side of deciduous teeth, which looks like double-layer teeth. In this case, you should take your child to the hospital stomatology department as soon as possible and pull out the stranded deciduous teeth. If the deciduous teeth fall off before falling off, it is called premature deciduous teeth fall off, which often causes the adjacent teeth on both sides to tilt to the gap between the missing teeth, which makes the gap between the missing teeth smaller and the permanent teeth sprout out of position due to insufficient gap. At this time, it is necessary to wear a gap retainer at the gap of the deciduous teeth to prevent the teeth on both sides from tilting until the permanent teeth erupt.

Are permanent teeth difficult to erupt? Early deciduous teeth fall off, and children are used to chewing and licking with gums, which will thicken and hinder the eruption of permanent teeth. Calcium deficiency is also an important reason for delayed eruption of permanent teeth. Parents should give their children calcium supplements in time.

When changing teeth, the front permanent teeth erupt from below or inside the deciduous teeth. The erupted permanent teeth are as big as adult teeth. It is normal for them to be slightly crowded and twisted, and they can be adjusted and arranged with the eruption of adjacent teeth and the growth and development of jaws. As long as it is not an inverted tooth (that is, covering the ground), it is generally not necessary to correct it.

2. Kindergarten Tooth Changing Day Teaching Plan

Activity objectives:

1. Understand that changing teeth is a normal physiological phenomenon, don't worry.

2. Understand the difference between deciduous teeth and permanent teeth, and know how to protect new teeth.

3. Learn the correct way to protect new teeth.

Activity preparation:

1. Investigate the number of children with and without changed teeth. Make a table for the children.

2. Make a big tooth model with foam board or other waste. If there is a tooth (deciduous tooth) in the middle of the tooth, you can pull it out at will, and then prepare a spare tooth (permanent tooth) to replace it.

3. Children's books: Tooth changing celebration.

4. Rehearse the live performance of "Tooth Changing Celebration". The important plot is the process of tooth replacement and the protection method of new teeth.

Activity flow:

(a questionnaire for teachers and children, analyze the situation of children's tooth change. Arouse the experience of children changing their teeth.

1. Teachers and children watch the questionnaire "Number of Teeth Changed by Children" together.

Teacher: Which children in our class have changed their teeth? How do you feel when you change your teeth?

2. The teacher and the child talk about the feelings when changing teeth, or ask the child who has not changed teeth to talk about the feelings at this time.

Teacher: Are you afraid when you change your teeth? Why? Do children who haven't changed their teeth need to change their teeth? Why?

Teacher: Why do people change their teeth? How about changing teeth?

3. Teachers and children * * * Summary: People began to change their teeth when they were five or six years old. Changing their teeth means that we have grown up and we should be happy! Children who have not changed their teeth should not worry, let alone be afraid. It is normal to change their teeth, and you will change your teeth soon. Today, we will hold a tooth-changing celebration to celebrate the growth of our children who have changed their teeth, and we also hope that children who have not changed their teeth will change their teeth as soon as possible. Everyone followed me and said, "yeah! I have grown up! "

(2) Teachers guide children to discuss. Understand the process of tooth changing 1. The teacher led the children to talk about the process of changing their teeth. Children speak freely.

Teacher: Please tell me about the process of changing teeth.

2. Teachers organize children to watch live performances and learn about tooth replacement.

3. The teacher summed up with children's books: the deciduous teeth are small and not hard enough; Permanent teeth are big and hard. When permanent teeth erupt, deciduous teeth begin to loosen and are eventually replaced by permanent teeth. Permanent teeth will accompany us all our lives, so we should take good care of them.

(3) Teachers guide children to learn the correct way to protect new teeth.

1. The teacher inspired the children to discuss: How should children protect their permanent teeth when they grow up?

2. The teacher organizes the children to continue to watch the scene performance. For example, the teacher operates the model of "permanent teeth" and says, "When I grow up, please don't lick and shake me with your tongue, because when I grow up, I will become untidy and ugly, and it will be inconvenient to chew food. Sometimes when the deciduous teeth haven't completely fallen out, I will soon grow out from the side. At this time, you should ask your parents to take you to the hospital to pull out the deciduous teeth that are about to fall out and make room for me. "

3. Teachers and children play the "Tooth Changing Celebration" game, so that children can play the roles of "deciduous teeth" and "permanent teeth", and gradually understand the process of tooth changing during the performance and learn how to protect new teeth.

Activity suggestion:

In daily life, teachers and children should take the initiative to pay attention to the changes of teeth. When a change is found, the child can take the initiative to tell the teacher, and the teacher can guide the child to treat it with a normal heart in time, pay attention to the child's experience, and let the child pass this stage smoothly.

3. Healthy thinking on the teaching of "the secret of changing teeth"

The following can be used for reference, and can also be changed according to your own reality:

Tooth changing is a healthy activity with the theme of "useful teeth", which aims to guide children to understand the health common sense and importance of tooth changing and maintain a happy and stable mood during the process of tooth changing. This activity is based on "Our Teeth" and further develops for children.

At the beginning of the activity, I asked the children directly, "Why did our teeth fall out? Will some children grow out of their teeth? " The children immediately discussed and raised their hands to speak. Some people say it will be longer, others say it won't be longer. The children's desire for exploration is getting stronger and stronger. Then I asked the children who had changed their teeth to tell you how their teeth fell out. What happened when it fell? Do you have new teeth? Throw the question to the children, and then let the children tell their peers themselves. Children are willing to listen to the experiences of their peers. After that, I will introduce the whole history of tooth development to children: let children know that if deciduous teeth fall out, permanent teeth will grow out, but permanent teeth are non-renewable, and let children know the importance of protecting teeth.

After that, tell the children the story of "when changing teeth" to let them know more about the story of changing teeth, what will happen and how to deal with it. Thus radiating the problem of how to deal with tooth replacement in the future. Finally, learn the children's song "Changing Teeth", so that children can further understand the content of children's songs and consolidate the common sense of changing teeth.

Large classes are the time for children to change their teeth, so this activity just meets the psychological needs of children, and instilling the knowledge of changing teeth in time for children has largely achieved the purpose of the activity.

4. What should children pay attention to when changing their teeth?

Pay attention to whether a deciduous tooth is kept or lost early. There is a certain time and sequence, which should be shedding rather than stopping the deciduous teeth. The consequence is often that permanent teeth can't erupt in the normal position.

Most children start to change their teeth at the age of five or six, and some children start at the age of four. Some children will lose their first deciduous teeth at the age of seven. Tooth loss usually begins with the next two incisors, and then the last two incisors.

The most common is that the lower front permanent teeth grow on the inner side of deciduous teeth, and the upper front permanent teeth grow on the outer side of deciduous teeth, which looks like double-layer teeth. What should I do in this case? Children should be taken to the hospital as soon as possible to remove the stranded deciduous teeth and make room for the eruption of permanent teeth. If the deciduous teeth fall off before they should, it is called premature deciduous teeth fall off, which often leads to the adjacent teeth on both sides leaning towards the gap of missing teeth, which makes the gap of missing teeth smaller, and the permanent teeth sprout out of position due to insufficient gap.

At this time, it is necessary to wear a gap retainer (customized by the hospital stomatology department) at the gap of the deciduous teeth to prevent the teeth on both sides from inclining, so as to maintain the eruption position of the permanent teeth until the permanent teeth erupt. Pay attention to whether the second permanent teeth are difficult to erupt and whether the deciduous teeth will fall off prematurely. Children are used to chewing and licking their gums, which will become thick and tough and hinder the eruption of permanent teeth.

Therefore, if the child has reached the age of changing teeth and the permanent teeth have not yet grown out, it is necessary to take the child to the hospital for examination in time and get the help of the doctor. Calcium deficiency in children is also an important reason for delayed eruption of permanent teeth. Parents should give their children calcium supplements in time.

When changing teeth, the front permanent teeth erupt from below or inside the deciduous teeth, and the erupted permanent teeth are the size of adult teeth. It is normal to have slight crowding, torsion or gap, which can be adjusted by itself with the eruption of adjacent teeth and the growth and development of jaw. As long as it is not malocclusion, it is generally not necessary to correct it, but it should be observed regularly for no more than half a year. If the deciduous teeth are still not aligned after complete replacement, you should see a doctor in time to avoid delaying treatment and causing difficulties in correction.

Pay attention to three to correct the child's bad habits. When changing teeth, both deciduous teeth and permanent teeth exist, and the permanent teeth just erupt. In particular, the "six-year-old tooth", which is the key to occlusion, has a large volume and many pits on the occlusal surface, which is easy to retain food residues. In addition, most children don't like brushing their teeth, like sweets, and often have decayed teeth. Once it happens, it should be treated as soon as possible. The most important thing at this time is to teach children to brush their teeth correctly.

When changing teeth, when deciduous teeth are loose and about to fall off, children are often used to licking loose teeth with their tongues. This is a bad habit, which will affect the normal eruption of permanent teeth. It is necessary to correct it in time to prevent malocclusion-that is, the teeth are not arranged neatly. Some children like to suck their fingers, bite their fingernails, pencils, handkerchiefs, stick out their tongues, bite their lips and hug their cheeks. These bad habits will also affect the arrangement of teeth, and some even affect children's pronunciation and breathing, so these bad habits of children must be corrected as soon as possible.

Pay attention to the malocclusion of four teeth, which will affect the child's appearance. During the tooth changing period, the teeth are replaced, the jaw is developing, and then the occlusal relationship is gradually established. Sometimes there will be temporary malocclusion, and in the process of tooth development, it can often adjust itself and return to normal. Some malocclusion causes the gap between the upper teeth to be too large, which will affect the facial development. You should go to the hospital for diagnosis and treatment, otherwise it will affect the child's appearance.

Precautions 5 Prevention and treatment of deciduous molars: deciduous molars are prone to dental caries, such as apical lesions caused by dental caries, which can affect the growth and eruption of secondary permanent teeth. Therefore, attention should be paid to the timely treatment and prevention of dental caries of deciduous molars, and there must be no misconception that deciduous teeth will be replaced sooner or later, and there is no need to treat them if they are broken. The doctor suggested that the deciduous teeth should be preserved as much as possible until the permanent teeth erupt. If deciduous teeth are missing prematurely, it will often lead to insufficient eruption space for secondary permanent teeth, which will lead to uneven dentition and even lead to permanent teeth being buried and not coming out.

Pay attention to eating chewy food when changing teeth. When the child is about six or seven years old, permanent teeth will begin to sprout one after another, replacing the original deciduous teeth. Although some children's permanent teeth have erupted, primary teeth often refuse to "give way", forcing permanent teeth to grow out of the inner side of primary teeth, forming "double-layer teeth", resulting in irregular arrangement of permanent teeth.

There are many reasons for the delay in extraction of deciduous teeth. The most common thing is that children eat too carefully and do not give full play to the physiological role of teeth. The main function of teeth is to chew food, which can promote the growth, natural absorption and shedding of milk roots.

Therefore, with the growth of children's age, children should be allowed to eat more chewy food, such as jellyfish, peanuts, sugar cane and so on. , so as to maintain a good effect on deciduous teeth and promote deciduous teeth to fall off on time. When the child's front teeth and back molars have erupted, you can give the child some celery, corn, apples and other foods to make the tooth change complete smoothly. In family life, parents should help their children to develop reasonable eating habits and oral hygiene habits from an early age, such as: controlling their sugar diet intake, urging and guiding their children to brush their teeth correctly (morning and evening), and gargling after meals or snacks; Educate children to eat less snacks and don't eat sweets and snacks before going to bed; Children's diet should not be too cold, too hot or too hard; Take your child for oral examination regularly to find and treat dental caries in time.

5. Kindergarten class language "the custom of losing teeth" lecture notes

Science teaching plan for kindergarten big class: when changing teeth

I. Significance of the activity

When the child grows to 5 or 6 years old, the original deciduous teeth begin to fall off gradually, which will affect the child's permanent teeth for life. If left unchecked, it will often have some adverse consequences. Teaching children the knowledge of changing teeth in time can help them adapt to this physiological change as soon as possible and learn to protect their teeth scientifically. Beautiful, neat and healthy teeth will be beneficial to children's future life and work.

Know your teeth

Educational goal

1. Learn about teeth and their functions.

2. Understand the knowledge of changing teeth, and know the deciduous teeth and permanent teeth.

Teaching preparation

A wall chart of adult teeth and children's teeth.

(3) Teaching process

1. Observe the teeth.

Count each other's teeth in pairs. Carefully observe the color, size and shape of each other's teeth, and find out the difference between front teeth, canine teeth and molars.

2. Introduce the different functions of incisors, canines and molars.

Guide children to talk about their front teeth, canine teeth and molars while eating food. Summary: Anterior teeth are thinner than other teeth, which can cut and bite food, while canine teeth are sharp and long, which can tear food; Molar teeth are wide and thick, which can grind food.

3. Show a wall chart to guide children to compare the number of teeth between adults and children and find out the differences.

4. Guide the children to discuss: Some children have lost their teeth, will they grow back?

5. Introduce deciduous teeth and permanent teeth.

6. Understand the knowledge of tooth change.

Guide the children who have experience in changing teeth to talk about how the teeth fell out and what would happen if they fell out. The teacher told the children that deciduous teeth will fall off when they are 5 or 6 years old, and then they will grow new teeth-permanent teeth. It hurts a little when I lose my tooth. Don't be afraid if you bleed a little. Rinse your mouth with cold boiled water when bleeding, and it will stop. Every child should always pay attention to whether his teeth are loose. If so, they will grow new teeth.

6. The name of the child's teeth in the process of changing teeth.

Time and sequence of tooth change People have to grow teeth twice in their lives, namely, primary teeth and permanent teeth.

There are 20 deciduous teeth, which usually start to erupt around 6 months, and grow together at the age of 2-3, and 28-32 permanent teeth (the number of wisdom teeth is 0-4), which generally start to grow around 6 years old, and 12- 13 years old (wisdom teeth vary from person to person) grow together with 28 teeth, so the tooth changing period is generally 6-62. There are certain rules for changing teeth. Simply put, it is "a certain time, a certain order, left and right symmetry, first down and then up", and left and right symmetry is aimed at teeth with the same name.

Most of the physiological shedding of the first deciduous teeth occurs around 6 years old, but some of them are as early as 4 years old or as late as 7-8 years old, so don't worry. Natural deciduous teeth have no roots, and their surfaces are gnawed. Parents should pay attention to observation and don't confuse it with deciduous teeth.

There are two different opinions about which permanent tooth the baby grows first. One is that the first permanent molar that usually grows around 6 years old grows close to the last deciduous molar, which is called six-year-old molar, and erupts earlier or at the same time as the lower central incisor. Another way of saying it is that the baby first changed the two front teeth in the middle of the lower row. The dentist said that every baby may be different.

Then, the baby has upper central incisors and lower incisors at the age of 7-8, upper incisors at the age of 8-9, first and second pairs of canines at the age of 9- 12, and permanent teeth at the age of 10- 12. Children should do a good job of calcium supplementation during tooth replacement, otherwise it will affect children's tooth development.

You can give your child Tihengjian brand calcium edge tablets, and the effect is good. It is safe and effective, and the dose is absolutely controlled within the range of 1/3-2/3 of RNI (daily recommended dose), which can achieve the purpose of safe calcium supplementation.

7. What are the precautions for children to change their teeth?

Precautions for children's tooth replacement are as follows: 1. Always pay attention to the development of teeth. Always pay attention to the growth of children's deciduous teeth and permanent teeth, and take children to the dentist regularly, so as to find problems at any time and solve them as soon as possible.

2. To develop a good habit of brushing your teeth, you should urge your child to brush his teeth every day. It is best to brush by adults before going to bed at night, especially the upper teeth are difficult to clean, which is most likely to lead to dental caries. There are also six-year-old molars that are not easy to brush, because they grow in the innermost part of the mouth, so we should choose children's toothpaste and toothbrush, and the toothbrush head should be as small as possible, otherwise the children will vomit easily when they get to the innermost part.

In addition to brushing teeth, it is best for children to rinse their mouths after eating food to maintain oral hygiene. 3. Eat hard food. Children should eat more foods with high cellulose and certain hardness during tooth changing, such as fruits, carrots, beans and corn. In order to maintain a good effect on deciduous teeth and promote deciduous teeth to fall off on time. On the other hand, it is also helpful to influence facial and eye movements through chewing, accelerate blood circulation and promote the development of gums, jaws and facial bones, which is both healthy and beautiful.

4, promote the absorption of calcium to strengthen children's absorption of calcium, and urge the baby to eat more foods with high calcium content, such as milk, cheese, tofu, canned fish and so on. At the same time, take enough vitamins C and D, because these two vitamins contribute to the absorption of calcium.
