How old is the latest to change your teeth?

When changing your teeth at the latest, you should pay attention to the time when you lose your teeth. It is not good for you to grow two teeth too early or too late in life. The first time, there were 20 deciduous teeth, which began to erupt at about 6 months, and all of them grew out at the age of 3. But all need to change. The following is the latest age for changing teeth.

The latest age 1 teeth-changing children began to erupt at about 6 months, and all deciduous teeth erupted at 2 ~ 3 years old, totaling 20. Permanent teeth began to grow around 6 years old, and deciduous teeth were pulled out. 12 years old to 13 years old, deciduous teeth were extracted and 28 permanent teeth grew. Some children arrive early and some are late. Generally, the third molars (also called wisdom teeth) begin to grow after 17 years old. Some people never grow wisdom teeth all their lives, or only grow one or two wisdom teeth, so the number of adult permanent teeth can be 28 ~ 32.

How old did the child start to change his teeth?

People have to grow teeth twice in their life, that is, primary teeth and permanent teeth. There are 20 deciduous teeth, which usually erupt at about 6 months, and grow at 2-3 years old, and 28-32 permanent teeth (the number of wisdom teeth is 0-4), which generally grow at about 6 years old, and 28 teeth 12- 13 years old (wisdom teeth vary from person to person), so the tooth replacement period is generally 6-650. There are certain rules for changing teeth. Simply put, it means a certain time, a certain order, left-right symmetry, first down and then up ",and left-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.

How to relieve the pain when changing teeth?

The process of tooth loosening and falling off is generally painless, but as the deciduous teeth begin to fall off, the child's six-year-old teeth will grow out, which may cause gum swelling and make the child complain about toothache. If the child has severe pain and needs to see a dentist, the doctor will decide whether it is necessary to diminish inflammation and relieve pain.

After all, it takes a process to change teeth. During this period, children may complain that they can't chew, but even if they don't eat well, they should ensure a reasonable and balanced diet. At this time, parents can make some foods that are easy to chew and swallow, such as vegetable soup and broth, to ensure the needs of the body, and encourage him to brush his teeth and clean his mouth.

What's wrong with changing teeth too early or too late?

1, premature tooth change:

The average child's first tooth falls off at the age of 5-7. If the teeth fall off before the age of 4, it is usually caused by internal reasons, or it may only be due to local oral reasons, such as metabolic disorder or periodontal disease.

Gingivitis is very common in children, but periodontal disease is very rare, so we need to know what causes deciduous teeth to fall off prematurely to protect the remaining deciduous teeth. Because it lays a good foundation for the normal growth of permanent teeth. Early diagnosis helps doctors to take effective measures to make permanent teeth erupt and arrange normally.

2. It's too late to change teeth;

If the child is over 7 years old and has not lost his teeth, he should be taken to the hospital for dental examination. General doctors will check whether permanent teeth are embedded in gums or have any developmental problems by taking X-rays. Generally speaking, the delay in changing teeth will not have any big impact on children. On the contrary, some doctors also believe that long-term incubation of permanent teeth under the gums can make them grow strong and break through the imprisonment of gums smoothly.

Matters needing attention in children's tooth replacement

1, always pay attention to the growth of baby's deciduous teeth and permanent teeth, and take the baby to the dentist regularly, so as to find problems at any time and solve them as soon as possible.

2, to urge the baby 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 baby will vomit easily when it reaches the innermost part. In addition to brushing your teeth, it is best for your baby to rinse his mouth after eating food every time to maintain oral hygiene.

3, the baby should eat more foods with high cellulose content and certain hardness during tooth changing, such as fruits, carrots, beans, corn and so on. In order to maintain a good stimulating 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 muscle movements through chewing exercise, accelerate blood circulation, and promote the development of gums, jaws and facial bones, which is both healthy and beautiful.

This applies not only to babies. I don't know if you have found that with the improvement of living standards, the food we eat is more and more exquisite, which is actually harmful to the health of our teeth. The degeneration of wisdom teeth (also called the third molar) is an example, so we should eat some hard and wear-resistant food from time to time to make our teeth, mouth and its nearby muscles get proper exercise.

4, strengthen the baby'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.

5. Try to avoid breathing through the mouth when the baby sleeps (usually due to tonsil hypertrophy's disease or nasal disease), because when the airflow passes through the mouth, the upper jaw is pressed upward and cannot develop downward normally, resulting in the upper jaw bulging upward, the left and right sides of the upper dental arch narrowing and the front protruding forward. The incisors that caused eruption not only leaned forward, but also arranged in disorder, resulting in missing teeth.

6. Correct some bad habits of your baby in time, such as spitting and biting your tongue, biting your finger or pencil, licking your teeth with your tongue, etc. These bad habits will affect the growth of baby's teeth and lead to tooth deformation.

7. Special protection should be given to the baby's first permanent molar-the sixth molar, which grows around 6 years old, because it plays a role in positioning and setting the height of teeth in the whole mouth, which has a great influence on the development of the baby's maxillofacial region and also plays an important role in the eruption and orderly arrangement of other permanent teeth.

8. Always educate your baby about safety and try to prevent tooth loss caused by trauma.

How old is the latest to change your teeth? Is it better to change your teeth sooner or later?

Premature tooth change

The average child is 5 to 7 years old, and the first deciduous tooth begins to loosen and fall off. Therefore, if a child's deciduous teeth fall off too early (before the age of 4), this phenomenon is not normal.

This may be the reason why the child's body is not good, or it may be that the child has oral problems, such as some periodontal diseases. Gingivitis is a common disease in children, but this kind of periodontal disease rarely causes tooth and bone damage in children. Therefore, it is necessary to go to the hospital for a check-up to find out the causes of premature tooth loss and prevent the remaining teeth from falling off prematurely.

It's too late to change your teeth.

After 7 years old, the baby's deciduous teeth have not fallen off normally, so you might as well go to the hospital for a check-up. In most cases, dentists will take dental films for children to see if permanent teeth are buried under the gums or have any developmental problems. Don't worry about delaying tooth replacement, because it has no effect on children's growth. On the contrary, some doctors believe that this situation will give permanent teeth more room to grow, which is very beneficial to the germination of permanent teeth in the future.

What should children pay attention to when changing their teeth

1, always pay attention to tooth development.

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. Develop a good habit of brushing your teeth

Children should be urged to brush their teeth every day, and it is best to brush with the help of 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.

Step 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 stimulating 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 muscle movements through chewing exercise, 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.

Strengthen children's absorption of calcium, and urge them to eat more foods with high calcium content, such as milk, cheese, tofu, canned fish and so on. At the same time, you should take enough vitamins C and D, because these two vitamins help to absorb calcium.

5. Avoid breathing through your mouth.

Try to avoid children breathing through their mouths when they sleep (usually due to tonsil hypertrophy's disease or nasal disease), because when the airflow passes through the mouth, the upper jaw is pressed upward and cannot develop downward normally, resulting in the upper jaw bulging upward, the left and right sides of the upper dental arch narrowing and the front protruding forward. Results The erupted incisors not only leaned forward, but also arranged in disorder, resulting in missing teeth.

Step 6 correct bad habits

It is necessary to correct some bad habits of children in time, such as spitting and biting your tongue, biting your fingers or pencils, licking your teeth with your tongue, etc. These bad habits will affect the growth of children's teeth and lead to tooth deformation.

7. Protect permanent molars

Special protection should be given to the first permanent molars of children around 6 years old, because they have the function of positioning and setting the height of teeth in the whole mouth, which has a great influence on the development of children's jaw and face, and also plays an important role in the eruption and orderly arrangement of other permanent teeth.

The above is an introduction to what children should pay attention to in the morning and evening when changing their teeth. I believe that parents have understood this point and hope to help everyone!

How old is the latest to change your teeth? 3 What happened when the child didn't change his teeth when it was time to change his teeth?

When children reach a certain age, they will begin to lose their teeth and then grow new ones. This process is called tooth replacement. A few days ago, a friend said that her daughter had not changed her teeth in the fourth grade of primary school, and other children of the same age had already changed their teeth. She is worried about whether her children are unhealthy. Next, let's look at the age at which children change their teeth.

Changing teeth is the process of deciduous teeth falling off and permanent teeth growing out. In the process of growth and development, there is a permanent tooth embryo under the root of each deciduous tooth, which gradually grows and develops. During the eruption of permanent teeth, on the one hand, the alveolar bone between the root of deciduous teeth and the embryo of permanent teeth is compressed, and the bone absorption becomes thinner through the action of osteoclasts until it is completely absorbed; On the other hand, the root of deciduous teeth is directly compressed, so that the root of deciduous teeth is gradually absorbed and becomes shorter and shorter until it disappears completely.

So the deciduous teeth began to fall off and the permanent teeth gradually grew out. Usually at the age of 6 ~ 7, the central incisors of mandibular deciduous teeth (central incisors) begin to shake and fall off, and soon, permanent central incisors grow here; At the same time, the first molar grows behind the second deciduous molar. Since then, other teeth have been replaced. Monocusps and bicuspids of permanent teeth can only grow after deciduous teeth in the same position fall off. Until 12 ~ 13 years old, all deciduous teeth fell off and permanent teeth were replaced.

Only permanent teeth will be produced afterwards. When the deciduous teeth should fall off, they stay. Doctors call this phenomenon retention of deciduous teeth, so children should be taken to the hospital for examination and treatment in time. Retained teeth with erupted permanent teeth but not deciduous teeth should be pulled out as soon as possible to avoid affecting the eruption of permanent teeth in the normal position. Don't pull out the primary teeth after the age of tooth replacement and the permanent teeth before they erupt. If permanent teeth are congenital missing, try to keep deciduous teeth.

As can be seen from the above, children have not changed their teeth at the age of changing their teeth, which should attract enough attention from parents. Pay close attention to the changes of children's teeth and report to the doctor in time once the situation is found, so as not to cause a lot of unnecessary trouble.
