Tips for starting to change teeth

1. Tell me more about the common sense of children during tooth changing. 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. After that, the single permanent tooth: 12~ 14 years old, the second molar grows behind the first molar, and the third molar grows after 18 years old. It is normal for some people not to have a third molar.

Problems needing attention in tooth replacement period

Retention of deciduous teeth: when deciduous teeth should be dropped, don't drop them. Doctors call this phenomenon retention of deciduous teeth, so they should take their children to the hospital for examination and treatment in time.

Main causes: dislocation of permanent tooth germ, local inflammation and absence of permanent tooth germ.

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.

Early deciduous teeth fall off: deciduous teeth fall off before they should, which is called early deciduous teeth fall off. It often causes the adjacent teeth on both sides to tilt 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. Wear a gap fixer at the gap between deciduous teeth to prevent the teeth on both sides from tilting until the permanent teeth erupt.

Difficult eruption of permanent teeth: permanent teeth produce eruption force during root development, which makes permanent teeth move to gum side and gradually erupt. This requires a process, especially the upper teeth. Permanent teeth do not erupt after the replacement period, which is called delayed eruption of permanent teeth.

The main reasons are: early deciduous teeth fall off, odontoma or cyst, and genetic factors hinder the abnormal development of permanent teeth themselves.

Tooth malocclusion: tooth replacement, jaw development, occlusion relationship gradually established, sometimes temporary malocclusion, in the process of tooth development, often self-adjustment, back to normal. Some malocclusion deformities can't be adjusted by themselves, which will affect facial development. They should go to the hospital for treatment.

Double-layer teeth: It is not uncommon for permanent teeth to come out before deciduous teeth fall off. This may be because the root of deciduous teeth is not completely absorbed. The relative position of deciduous teeth and permanent teeth can be determined by oral X-ray, so as to diagnose whether deciduous teeth can fall off or need to be pulled out.

It hurts a little when changing teeth: the process of loosening and falling off teeth generally does not hurt, but as deciduous teeth begin to fall off, they will grow "six-year-old teeth", which may cause gum swelling and make children complain about toothache. If the pain is severe, you need to see a dentist to see if you need to relieve inflammation and pain.

Six-year-old tooth decay: about 6 years old, behind the second deciduous molar, the first permanent molar grows quietly, also called "six-year-old tooth" It does not replace any deciduous teeth, and it is easy to mistake them for deciduous teeth. Clinically, many children have dental caries at the age of six, which have developed into pulpitis or periapical periodontitis. In order to prevent dental caries of six-year-old teeth, pit and fissure sealing should be carried out as soon as possible.

Nutrition and diet of infants with tooth replacement

With the growth of age, children should eat more chewy foods such as jellyfish, peanuts, sugar cane, spiced beans, etc., so as to maintain a good stimulating effect on deciduous teeth and urge them to fall off on time. When the child reaches the age of 10, the front teeth and back molars have erupted. Parents can add some celery stalks, corn, apples and other foods, so that tooth replacement can be completed smoothly and children can have a healthy and tidy permanent tooth.

Prevention of inferiority complex during tooth replacement

The child's self-esteem has been established during the tooth changing period. I care if the front teeth look good. If you joke about this, children will feel inferior and even lick their teeth desperately, hoping to grow up quickly, but the result is counterproductive. You can tell children that white swans are all made by ugly ducklings. The front teeth fall off and look ugly. This is a transformation process, which proves that "you are about to grow up", and every child has to go through this process when growing up.

2. What should children pay attention to when changing their teeth? For children aged five or six, health care is very important when changing teeth.

Because the new permanent teeth will accompany them for almost a lifetime, it is directly related to whether the children's teeth are neat and beautiful in the future, and will affect their diet, appearance and even psychology. Therefore, parents should strengthen the care of their children during this period, so that their children can have healthy teeth in the future.

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 stimulation 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 stimulating 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.

3. What should children pay attention to when they start changing their teeth? 4- 12 years old is the period of changing teeth, which is normal.

It usually grows naturally with the wind. It is necessary to see a dentist unless two teeth grow together. People grow teeth twice in their life, once they are deciduous teeth and once they are permanent teeth, that is, adult teeth.

After birth, the permanent tooth embryo begins to calcify, and it begins to erupt at the age of 6-7, 32 * * *, and usually comes out at the age of 20. When the permanent teeth erupt, the deciduous teeth fall off one after another, and the time sequence is as follows: at the age of 6, the next two incisors grow out, and at the same time, the first molar, commonly known as molar, grows behind the second deciduous molar, one above, one below, one on the left and one on the right; The front teeth of the next two deciduous teeth fell off.

At the age of 7, the upper two incisors grew out and the upper two deciduous incisors fell off. At the age of 8, the upper and lower incisors appeared and the upper and lower deciduous incisors fell off.

At the age of 9- 10, the lower canines and the first pair of canines (one for the upper, lower, left and right sides), the lower deciduous canines and the first deciduous molars (one for the upper, lower, left and right sides) fell off. 10 at the age of one, the upper canines appeared and the upper deciduous canines fell off (one on the left and one on the right).

When ll- 12 years old, the upper and lower second pair of canines (one left and one right) emerged, and the upper and lower third deciduous molars fell off (one left and one right). Generally, all deciduous teeth fall off at the age of 12- 13, then permanent teeth are molars, the second molars are at the age of 12, and the third molars are at the age of 18. Once every six years, it is called a 6-year-old tooth, but some people come out around the age of 30, while others don't.

Of course, we should also pay attention to oral hygiene, brush our teeth carefully, and don't chew sideways. Remove the residual roots and crowns of deciduous teeth in time.

In addition, two newly grown upper central incisors (incisors) often do not move together, and there is a gap between them, which causes parents' concern. Do they need corrective treatment? This is because all the front teeth of the four deciduous teeth have fallen off, only two middle teeth have grown, and there is a gap between the two teeth. It doesn't matter. When the two lateral incisors gradually grow into the oral cavity, the long axis direction of the two central incisors changes, the two central incisors also approach each other, and the gap between the two teeth disappears.

4. knowledge of tooth protection to protect teeth, we must first understand the structure of teeth. Teeth are the hardest organs in the human body. It has the functions of biting, tearing, grinding food and assisting pronunciation. There are two pairs of teeth in a person's life: one pair is deciduous teeth, the upper and lower jaws have 20 teeth, and 10 teeth. It began to erupt about half a year after birth and came out about two and a half years old. From 7 years old to 12, deciduous teeth fall off one after another. The other pair is permanent teeth, ***32, and the upper and lower jaws are 65,438+06 respectively. The deciduous teeth gradually change from the age of 6, and all the permanent teeth erupt around the age of 12 except the third molar. The third molar usually erupts after the age of 20, also called wisdom tooth. Wisdom teeth will never come out, so 28~32 permanent teeth are normal.

Teeth are divided into three parts: crown, neck and root. The crown is the part we can see, and it is the part where the teeth are exposed outside the gums. The surface of the crown is covered with a layer of enamel, which is the hardest tissue in the human body, and its hardness is similar to that of the time. The root is embedded in the alveolar process of the upper and lower jaws. The root surface is covered with a layer of cementum. The neck of the tooth is a slightly thinner part between the crown and the root of the tooth, which wraps the gum. Teeth are mainly composed of dentin, and the internal cavity is called tooth cavity. The cavity of movable teeth is filled with connective tissue, nerves and blood vessels, which are collectively called dental pulp. Blood vessels and nerves enter and exit from the apical foramen of teeth. When suffering from dental caries, bacteria corrode enamel and dentin and enter the pulp cavity, which stimulates nerves and makes the pain unbearable. (See Figure 37) Students should take the following measures to protect their teeth:

1. Develop good brushing habits. Rinse your mouth with warm water after meals and brush your teeth once in the morning and evening. Don't brush your teeth too often, it will damage your teeth, and don't brush your teeth for too long. Brush cheese

5. How old did the child start to change his teeth? Hello, we normal people usually have two kinds of dentition, namely deciduous teeth and permanent teeth. Under normal circumstances, deciduous teeth grow slowly in infancy from six or seven months, and gradually fall off from six or seven years old to grow permanent teeth. Generally, permanent teeth will be replaced at the age of 12 or 13. In the same year, girls will be younger than boys. Now you can consider calcium supplements and high-protein foods. By the age of 65,438+02 to 65,438+04 (the average age in China), all primary teeth were replaced. A * * * needs to replace 20 teeth, and a * * * needs to replace 4 front teeth. (Suitable for 6-7 years old) Upper and lower deciduous lateral incisors, one * *.
