Children should pay attention to changing their teeth.
Note 1: Time and sequence of deciduous teeth falling off.
There is a certain time and order for deciduous teeth to fall off. Teeth usually fall off from 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 situation? 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.
Note 2: Is it difficult for permanent teeth 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. 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 and torsion, 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 arrangement of deciduous teeth is still uneven after complete replacement, you should see a doctor in time to avoid delay in treatment and cause correction difficulties.
Note 3: Correct your child's bad habits.
When changing teeth, deciduous teeth and permanent teeth exist at the same time, and permanent teeth just erupt, especially "six-year-old teeth", which are the "key to occlusion", with large volume and many pits on the occlusal surface, and are easy to retain food residues. In addition, most children are prone to dental caries because of incomplete brushing. The most important thing at this time is to teach children to brush their teeth correctly. In the process of 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 and should be corrected in time.
Note 4: Dislocation and occlusion of teeth will affect the appearance.
During the tooth changing period, the child's teeth are changing, the jaw is developing, and then the occlusal relationship is gradually established, and sometimes temporary malocclusion occurs. In the process of tooth development, they can often adjust themselves and return to normal. Some malocclusion deformities, such as the gap between the upper teeth caused by the low labial frenum position of the upper lip, cannot be adjusted by itself, which will affect the facial development. You should go to the hospital for treatment, otherwise it will affect the child's appearance.
Note 5: Prevention and treatment of deciduous molar caries.
Primary molars are prone to dental caries during tooth replacement, such as apical lesions caused by dental caries, which can affect the growth and eruption of secondary permanent teeth. Therefore, we should pay attention to the timely treatment and prevention of deciduous teeth caries, and we must not have the wrong idea that "deciduous teeth will be replaced sooner or later, and if they are broken, there is no need to treat them." 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, resulting in uneven dentition.
Note 6: Eat chewy food when changing teeth.
When the child is about six or seven years old, permanent teeth 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 eat more chewy food to maintain a good stimulating effect on deciduous teeth and urge them to fall off on time. When the child's front teeth and back molars have erupted, you can add some celery, corn, apples and other foods to make the tooth change complete smoothly and let the child have a healthy and tidy tooth.
Changing teeth is a process that every child must go through. As parents, we should closely observe the development of children's teeth, so that children can successfully pass the tooth changing period and grow a healthy and beautiful tooth.
(1) Observe the changes of children's teeth.
With the growth of children's age, small deciduous teeth can no longer adapt to the growth of jaws and the increase of chewing power. Primary teeth began to fall off physiologically at the age of 6, and all of them were replaced by permanent teeth at the age of 12. Due to the growth and development of permanent tooth germ in jaw and the movement of teeth to occlusal surface, the root tissue of deciduous teeth is absorbed, and the deciduous teeth gradually loosen and finally fall off. The deciduous teeth have no roots, and the deciduous teeth are biting. Children should pay attention to observation when deciduous teeth fall off, so as to distinguish them from broken roots of deciduous teeth.
(2) Try to avoid children being injured.
Some parents will feel uneasy and suspicious when they find their children's newborn permanent teeth loose. In fact, this is because the newly erupted teeth have not been fully formed, the pulp cavity and apical foramen are large, and the cementum at the apical part is very thin. During this period, if the apical inflammation is caused by trauma and infection, the apical foramen can no longer be closed, which is very troublesome to treat. The age when children change their teeth is a lively and active period, and it is easy to suddenly collide and fall down during running, frolicking and slapstick, resulting in maxillofacial trauma, especially the upper teeth. Therefore, in this period, parents should pay more attention to let their children avoid injury.
(3) Don't worry about the gap between the front teeth.
Some parents found that there was a gap between their children's two new front teeth, and some even showed a figure of eight, and they were very worried about their children's front teeth. In fact, the eruption of permanent teeth has a certain time and order. The eruption time of upper central incisors (commonly known as incisors) is 6-9 years old, and lateral incisors are 7- 1 1 year old. Therefore, at the age of 7- 1 1, there will be a gap between the child's two front teeth. As long as the lateral incisors erupt, the gap disappears naturally. Occasionally, there may be extra teeth between the two front teeth, which may cause a gap between the two front teeth. This can be confirmed by X-ray examination, and then the extra teeth are removed to close the gap.
(4) "Tiger tooth" can't be pulled out.
In the order of the exchange of primary teeth and permanent teeth, the eruption of canines is later than that of the first pair of canines. Because the alveolar bone in the anterior tooth area is occupied by other teeth when the fangs erupt, they can only erupt from the labial side, so some children's fangs often protrude to the labial side to form "tiger teeth". Some parents think this tooth is ugly and ask the doctor to pull it out. This is not right. Fangs are the longest and strongest teeth in the whole mouth, and their function of tearing food is irreplaceable by other teeth. If you lose it, children will often be unable to chew sugar cane or eat ribs, which will also affect their chewing power. If correction is needed, the doctor will also pull out the first or second bicuspid teeth to achieve the purpose of correction.
(5) Understand the period of "temporary mismatch"
Finally, it is worth mentioning that during the alternation of primary teeth and permanent teeth, the arrangement of teeth is often mixed, sometimes even messy, which is called temporary malocclusion in medicine. Some parents are very worried about this and ask doctors to correct it as soon as possible. In fact, there is a potential tendency for human teeth to be arranged neatly. When deciduous teeth and permanent teeth alternate, the tooth arrangement may adjust itself. Before deciduous teeth and permanent teeth alternate, there is no need to rush to correct them, but to observe and follow up. Some children's permanent teeth will slowly line up. Even if correction is needed, it should be done after the replacement of deciduous teeth and permanent teeth. Usually at the age of 13- 15, when the permanent teeth erupt to a certain height, the manufacture and wearing of our appliance can be accurate and effective.
If you want to change your teeth, chewing exercise is essential.
It is time for my son to change his teeth. But the new teeth have come out, and the longer they are, the bigger the old deciduous teeth are. My son feels awkward when eating. I'm a little worried. Grandma said, "It's all right. Children change their teeth like this. " After a few days, the old deciduous teeth are still growing firmly there. I was worried that this would make my new teeth grow crooked, so I took my son to the dentist. The dentist examined my son's teeth and told me and my son that this old deciduous tooth must be pulled out. Otherwise, new permanent teeth with dark hair will grow out from the lingual side or labial side of deciduous teeth, forming "double-layer teeth", resulting in irregular arrangement of permanent teeth. This tooth of my son has been pulled out. I asked the dentist, "Why is the baby's deciduous teeth like this? Will he have to go to so much trouble to change every tooth in the future? " The son is also very strange: "Why don't other students have their teeth pulled out?" The dentist gave us a simple answer: "There are many reasons for the delay in the extraction of deciduous teeth. The most common reason is that the food children eat is too thin and does not give full play to the physiological stimulation of teeth. The main function of teeth is to chew food, which can promote the growth and development of milk roots and their natural absorption and shedding. Therefore, with the growth of children's age, children should be allowed to eat more chewy foods, such as jellyfish, beef jerky, peanuts, sugar cane and spiced beans. So as to maintain a good stimulating effect on deciduous teeth and promote them to fall off in time. When the child's front incisors and back molars have erupted, eat crude fiber food, such as celery, corn, apples and so on. In order to increase, you can successfully complete the tooth replacement. " My son and I realized that changing teeth had something to do with eating. When we got home, we told grandma what the dentist said. Grandma said: "Yes, things are getting more and more elaborate now, and I'm afraid the child will not digest well." The dishes cooked at home are also soft and rotten, and it seems that they really need to be changed. "
Children should prevent deciduous teeth from falling off when changing their teeth.
The child began to change his teeth at the age of five or six. Generally speaking, permanent teeth will be directly below deciduous teeth, and the roots of deciduous teeth will be absorbed during eruption. In this way, the deciduous teeth will be shortened like a tree without roots, and the roots will slowly shake until they fall off. Even if it is not pulled out, the deciduous teeth will fall off by themselves.
In the process of changing teeth, some children will have deciduous teeth but permanent teeth. Some parents think this is because there is too much calcium, but this situation has little to do with calcium. The main reason is that the deciduous teeth are densely arranged and the permanent teeth are large, so the original deciduous teeth can't accommodate the new teeth, so the new teeth can't grow normally under the deciduous teeth, resulting in the root of the deciduous teeth not being absorbed, the old teeth not falling off, and the new teeth have grown out.
The dentist pointed out that when children change their teeth, the old and new teeth coexist, and the deciduous teeth should be pulled out. After the deciduous teeth are pulled out, the permanent teeth will slowly move to the original position of the deciduous teeth due to the thrust of the tongue. At this time, if there is enough space, the permanent teeth can grow straight. If we ignore the juxtaposition of new and old teeth, it may lead to uneven tooth arrangement or improper occlusion, which may easily lead to tooth decay due to incomplete cleaning. Therefore, parents should pay special attention to the overlapping phenomenon of new and old teeth during their children's tooth replacement and deal with it correctly.
Changing teeth should also be "disciplined"
More and more older children and children begin to pay attention to their oral beauty, or wear braces, or have surgery, saying that it is not an exaggeration to arm their teeth.
It is said that wearing braces is also a fashion in Japan, Europe and America. In fact, it is not the popularity of braces, but the loose teeth and unscrupulous growth that affect the owner's appearance.
In fact, if the strict "standard normal jaw" is taken as the reference data, the malocclusion rate of adolescents in China can be as high as 80-90%. Knowing this figure, it is not difficult for us to understand why more and more parents are beginning to pay attention to their children's dental problems.
The causes of malocclusion are not only human evolution factors, but also environmental and replacement factors. Parents should be reminded that it is best to correct malocclusion from the age of 12. Before this, the baby's deciduous teeth may not have been replaced. After that, it will take more time and energy to correct them.
Why is it so hard to find a beautiful woman with "teeth like shells"
The ancients often used the word "teeth like scallops" when describing beauty. According to modern people's aesthetic concept, people with neat white teeth are not only beautiful, but also more confident. Why are there so few "teeth like scallops" now, but so many people with irregular dentition? Shen Gang, a doctor at City Nine Hospital, explained the reason.
The first is the factor of evolution. In the process of human evolution, many organs are degenerating, and the degree of degeneration of each organ is different. Relatively small alveolar bone can not accommodate relatively large teeth, resulting in uneven crowding of teeth.
Followed by environmental factors. Because of "never tired of eating essence and cooking essence", the chewing function can't be fully exerted, and the alveolar bone can't be stimulated enough, which limits the growth of the jaw, resulting in crowded teeth. Other children have the habit of sucking their fingers, licking their tongues, biting their lower lips and breathing through their mouths when they are young, which has a bad influence on the normal eruption and position arrangement of teeth, and also causes uneven dentition.
Replace obstacles. For example, premature or overdue deciduous teeth will lead to the eruption of hereditary permanent teeth, which is also an important reason for uneven dentition.
"However, it is hard to find an ideal jaw with absolutely neat teeth in life. It is good for the average person to reach the standard jaw. Therefore, there is no need to affect confidence. " Dr. Zou Derong from the Department of Stomatology of Shanghai Sixth Hospital said.
When will children learn to brush their teeth?
Studies have proved that tetracycline drugs can cause discoloration of children's teeth. It is necessary to add complementary food to children in time, which can not only supplement nutrition, but also help the development of deciduous teeth, such as adding biscuits and baking steamed bread slices to exercise the chewing ability of deciduous teeth. Give some fruits and vegetables to children about 2 months old.
Many parents often wait for their children to brush their teeth before they start to develop the habit of brushing their teeth, but it is too late. Once a child's deciduous teeth erupt about 6 months after birth, after breastfeeding or eating, parents should wrap gauze on the index finger to help clean the tooth surface, teach color teeth at about 3 years old, and help the child brush his teeth under the supervision of parents before 4 years old.
Children should use the brush edge method. First, use the children's health care toothbrush, with a small brush head and soft bristles. Brush your teeth along the direction of the crown, which can not only brush off the food soft dirt on your teeth, but also massage your roots. Children should choose medicinal toothpaste, such as fluoride toothpaste, which can remineralize enamel and prevent bacteria from adhering to the tooth surface.
In addition, parents should urge their children to develop good hygiene habits.
Are your children's teeth neat?
How do I know if my child has dentition disorder? The following are the four main manifestations of uneven teeth summarized by Associate Professor Qian of the Ninth Hospital. Look at the baby's teeth and you will understand:
Tooth crowding
The tooth arrangement in the dental arch is not a natural and beautiful arc, but protrudes forward or sinks inward, or even overlaps with each other.
Protrusion of upper anterior teeth
The teeth in the front section of the upper arch protrude forward, driving the upper lip upward, which will seriously lead to the failure of the upper lip to close naturally.
Protrusion of lower anterior teeth
Contrary to the normal mandible, the lower incisors bite in front of the upper incisors, driving the lower lip to protrude forward.
Upper and lower teeth protrusion
Commonly known as "fangs". The upper and lower teeth protrude forward at the same time, which makes the whole lip protrude forward, which seriously leads to the failure of the upper and lower lips to close naturally, forming a "lip opening and tooth opening".
How old is the best time to correct teeth?
By the age of 12, most of the permanent teeth in the mouth have erupted, and the irregular teeth are basically shaped. During this period, the development of children's maxillofacial region is still in a period of rapid growth and development, which makes the efficiency of tooth movement and alveolar bone reconstruction reach the best level. In addition, at this time, children's psychological development has become increasingly mature, so dentists generally believe that 12 years old is the best period for orthodontics.
Orthodontics is mainly carried out by wearing appliances. Before wearing the appliance, the doctor will take a picture of the child to understand the development of the jaw and make a plane design. Sometimes it may be necessary to pull out the first and second fangs at the back first to make room for the normal arrangement of teeth.
After the teeth are fitted with the appliance, they need to be reexamined in the hospital once every one to two weeks at first, and the doctor will adjust the tightness of the appliance, and the reexamination time can be extended to one to two months later. In this process, what parents need to do is to cooperate with doctors, help children overcome the pain and tingling caused by discomfort, protect corrective devices, cooperate with the application of replacing rubber bands and extraoral arches, and follow up in time in strict accordance with the requirements of doctors.
Usually, it takes about two years for the appliance to reach a stable and satisfactory standard jaw state, and then it needs to wear a retainer for six months to one year to further consolidate the orthopedic effect. Therefore, orthodontics is also a long and slightly painful process, and parents and children should make corresponding psychological preparations.
