Whether children like it or not, their baby teeth will fall out one day. 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 (generally speaking, deciduous teeth grow early and fall off early). Tooth loss usually begins with the next two incisors, and then the last two incisors.
Special nursing care of children during tooth replacement
Health care during tooth changing is very important, which is directly related to whether the children's teeth are neat and beautiful in the future. Therefore, young parents should strengthen the care of their children during this period, so that their children can have good teeth in the future.
Please pay attention to whether the deciduous teeth are stuck or fall off prematurely.
There is a certain time and order for deciduous teeth to fall off, which should not be called deciduous teeth retention. The consequence is often that permanent teeth cannot erupt in normal positions. 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, a gap retainer (customized by the Department of Stomatology of the hospital) should be installed at the gap of the deciduous teeth to prevent the teeth on both sides from tilting, so as to keep the eruption position of the permanent teeth until the permanent teeth erupt.
Pay attention to whether permanent teeth are difficult to erupt.
The deciduous teeth fall off prematurely, and children are used to chewing and licking with gums, which will become thick and tough, hindering 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.
The eruption of permanent teeth should be observed and corrected regularly.
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 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.
Pay attention to the cleanliness of the child's mouth.
When changing teeth, both deciduous teeth and permanent teeth exist, and the permanent teeth just erupt, especially the "six-year-old teeth", which are the "key to occlusion" and have a large volume, and there are many pits on the occlusal surface, which are easy to retain food residues. In addition, most children don't like brushing their teeth and like sweets, so dental caries often occur. 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.
Pay attention to correcting children's bad habits.
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.
Pay attention to the malocclusion of teeth.
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.
Pay attention to the 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, attention should be paid to the timely treatment and prevention of deciduous molar caries, and there must be no misconception that deciduous teeth will be replaced sooner or later. If they are broken, there is no need for treatment. 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.
Eat chewy food when changing teeth.
When the child is about six or seven years old, permanent tooth buds 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 not 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 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.
Frequently asked questions about tooth replacement q&; A
Teeth won't fall out?
It usually lasts for several months from the beginning of root loosening to real shedding, and it will fall off when you are not paying attention, such as when eating. However, some teeth are like a tied thread that will never fall out. At this time, it may affect chewing or make children feel unhappy. In this case, you can ask the child to try to turn it around. If the root of a tooth falls off completely, a slight rotation will make it fall off, but it must not be forced, let alone yanked, because if only half of the root falls off, the consequences of forced pulling are easy to cause injury and infection.
It hurts a little?
Generally, the process of tooth loosening and shedding is painless, but with the shedding of deciduous teeth, the child's "six-year-old teeth" will grow out. (Children begin to grow their first permanent molars at the age of 6, which are located behind the last deciduous teeth in the upper and lower jaws. Because they began to erupt at the age of 6, they are also called "six-age teeth". ) This may lead to swollen gums and make children complain about toothache. If the pain is severe and you need to see a dentist, the doctor will decide whether it is necessary to diminish inflammation and relieve pain.
New permanent teeth may not be as white as deciduous teeth, but the difference is so small that almost no one will notice. Moreover, don't be surprised that the child's new "big teeth" look incongruous with his face. Their heads will continue to develop, but their permanent teeth will not grow any longer.
After all, changing teeth is a process. Children may complain that they can't chew. Even if he doesn't eat well, he should ensure a reasonable and balanced diet. He can make some foods that are easy to chew and swallow, such as vegetable soup and broth, to ensure the needs of the body. At the same time, encourage him to keep brushing his teeth and clean his mouth.
Tooth change: too early? Too late?
Premature delivery: The average child's first tooth falls off between 5 and 7 years old. If the teeth fall off before the age of 4, it is usually caused by internal reasons, which may be systemic or just 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. (Some people think that deciduous teeth will be replaced sooner or later, and it doesn't matter whether it is early or late, but normal deciduous teeth can promote jaw development, maintain the eruption position of subsequent permanent teeth, and guide the eruption of subsequent permanent teeth. If the deciduous teeth are missing prematurely due to trauma, periodontal disease and other reasons, children should be taken to see a doctor to make retainers to ensure that their gaps will not narrow and lay 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.
Too late: if the child is over 7 years old and has not lost his teeth, he should also be taken to the hospital for examination. Doctors usually take an X-ray to check whether the permanent teeth are embedded in the gums or have any developmental problems. Generally speaking, the delay in changing teeth will not have any big impact on children. On the contrary, some doctors also believe that permanent teeth can be "bred" under the gums for a long time, making them grow strong and break through the "imprisonment" of the gums smoothly.
How long does it take for the teeth to finally fall off?
Q: One of my son's teeth began to loosen five weeks ago, and it hasn't fallen off today. It looks very stable. The permanent teeth have been exposed from the back, and there seems to be an inward growth trend. I'm very worried. If primary teeth don't make room for permanent teeth in time, will they have to be filled in the future?
A: The time for deciduous teeth to fall off is not fixed, depending on the absorption degree of deciduous teeth roots when permanent teeth erupt. And some depend on the position of permanent teeth or whether the deciduous teeth have been traumatized. Sometimes this will lead to the root of deciduous teeth can not be completely reabsorbed, so that deciduous teeth can not fall off on their own, and dentists need to take them out by surgery.
Some children want to drill out their permanent teeth before their deciduous teeth fall off, and as a result, they grow two rows of teeth. As you said, the two permanent incisors under the child grow behind the deciduous teeth, which is not a rare phenomenon, but a "double tooth" phenomenon that children often have when changing teeth. This is probably caused by the root of deciduous teeth not being completely reabsorbed. Doctors can generally determine the relative position of deciduous teeth and permanent teeth through oral X-ray photography to help him diagnose whether deciduous teeth can fall off or need to be pulled out. Once deciduous teeth fall off or are pulled out, permanent teeth usually grow to the correct position, but if there is not enough room for permanent teeth to grow, early intervention is better than later correction.
Can crowded deciduous teeth lead to permanent teeth arrangement problems?
Q: I heard from a friend that if the baby's deciduous teeth are not closely arranged, but there is a gap, it will be beneficial to the growth of permanent teeth. But my daughter's deciduous teeth are next to each other, and there seems to be no room. Will this bring problems to the arrangement of permanent teeth?
A: Generally speaking, the reason for the crowded permanent teeth is the contradiction between the width of the teeth themselves and the width that the dental arch can provide. Because the size of teeth has been determined long ago, the width of dental arch is generally set before the age of 3, and whether permanent teeth are crowded or not is related to the space between deciduous teeth. As your friend said, if the deciduous teeth are closely connected, it is more likely to cause permanent teeth crowding. But it is not absolute, because the permanent molars that children grow will be smaller than the deciduous molars, which will prepare a little space for other teeth. If necessary, you can use this space to relieve the crowding of front teeth, which depends on the advice of dental plastic surgeons.
Why do some children have sparse teeth and cracks? Does it need to be corrected immediately?
Children's teeth are sparse and there are three common situations.
The deciduous teeth are sparse and have cracks, which is also called physiological gap. The existence of these gaps is beneficial to the dentition arrangement after the eruption of permanent teeth in the future.
When changing teeth, there is a gap between the two upper incisors, which is a temporary phenomenon in the process of changing teeth. With the eruption of the teeth on both sides of the front teeth, the gap will gradually decrease to completely disappear, but when the gap between the two front teeth is particularly large, please ask a doctor to check whether there are more teeth.
There are cracks in the sparse permanent teeth. One is that permanent teeth are smaller in shape, such as fangs or too small teeth. The other is that permanent teeth have congenital missing teeth. You can go to the hospital and ask a doctor to close the gap through orthodontics or restoration.
The child's newly changed tooth looks particularly big. Will it get smaller in the future?
The front teeth that have just been replaced by children are particularly large and do not match the face. Some people call this period the "ugly duckling" stage of children.
Indeed, after the eruption of teeth, the size of the crown will no longer change, but the alveolar bone of children will increase with the continuous development of the root, and the mandible will also increase with the increase of the number of permanent teeth. With the growth and development of children, the face gradually becomes bigger and fuller. At that time, the child's face and teeth will become symmetrical and harmonious, and the front teeth will not feel particularly large.
Pay special attention to
Always check whether your child's deciduous teeth fall off on time, and don't pull them out easily to avoid dislocation and deformity when permanent teeth grow out.
Pay attention to observe whether the child's permanent teeth gradually erupt with the deciduous teeth falling off. If it is found that permanent teeth cannot erupt after deciduous teeth fall off, you should go to the hospital to remove a small piece of gum to expose the edge of the crown, so that permanent teeth can erupt as soon as possible.
Prevent "double-layer teeth", that is, permanent teeth have erupted, but deciduous teeth have not yet fallen off. On the one hand, it will cause permanent teeth to fail to erupt in the normal position, on the other hand, it will affect the normal development of the jaw, and it should be corrected at the hospital immediately.
You need more calcium during tooth changing, so you should pay attention to strengthening nutrition for your child and eat more foods rich in vitamins and calcium, such as vegetables, fruits, milk and shrimp skin.
Tetracyclines will be deposited on bones and teeth, which will make the newly grown permanent teeth yellow, so they should be banned before and during tooth replacement.
Educate children not to lick the erupted permanent teeth with their tongues frequently, so as to avoid protruding front teeth or malocclusion of upper and lower teeth.
Educate children to develop good hygiene habits. Brush your teeth in the morning and evening, and rinse your mouth after meals or snacks such as candy. When choosing children's dental care products, children's soft toothbrush and children's fruit-flavored toothpaste should be selected.
