Both parents hope that the baby can grow a white and neat tooth, but when should the baby change his teeth? Why are the new front teeth crooked? Why is the gap between the new front teeth so large? Young parents are often confused. Some babies will have double-layer teeth, or deciduous teeth will fall off and new teeth will not grow. What should I do?
There are two teeth in a person's life. One is a deciduous tooth, which begins to grow when the baby is 6 months old. There are 20 teeth, about two years old. Starting with my first tooth, which was about 6 years old, I changed my second tooth, which is a permanent tooth. At this time, the deciduous teeth began to fall off in sequence, and the number of permanent teeth was 8 ~ 12 more than that of deciduous teeth, that is, each row of newly grown permanent teeth was 14 ~ 16, and the total number of permanent teeth was 28 ~ 32 (some people never had wisdom teeth).
First of all, parents don't have to worry about the baby's newborn front teeth being uneven or grinding their teeth.
After the new teeth grow out, the cutting edge (that is, the cusp) is uneven and needs to be gradually smoothed, and the baby will involuntarily bite and "align". When I was about 7 years old, the upper two front teeth came out. Parents found that the children's two front teeth were not next to each other, and there was a gap in the middle, fearing that the two front teeth would separate. In fact, this is the development process of teeth after eruption. After the teeth on both sides grow out, the front teeth will slowly close. If the gap is too large and affects the growth of teeth on both sides, so that the gap cannot be closed, you should go to the hospital to find a dentist to correct it.
Secondly, when the child's new front teeth grow out, many parents think that the child has "big teeth", which is ugly.
There is no need to worry about this. If the permanent teeth are as big as the deciduous teeth, as the children grow up day by day and the maxillofacial region develops into adulthood, the teeth will become ugly because they are too small.
Third, children often have "double teeth" when changing their teeth.
Finally, if permanent teeth are delayed, it may be that the position of permanent teeth in the jaw is abnormal, which hinders the growth of permanent teeth. It may also be related to children's health, nutritious diet and heredity. Take your child to the hospital for a comprehensive examination and symptomatic treatment. You must not use supplements, hormones and other methods to promote tooth growth, otherwise it will bring bad consequences.
Parents should always observe the growth of children's new teeth after their children begin to change their teeth. Some children have bad habits such as sticking out their tongues, sucking their fingers, licking their teeth, biting pencils and biting their lips when changing their teeth. Parents should correct it in time, otherwise it will cause tooth deformity and affect the child's bite force.
This is because the front teeth generally grow out of deciduous teeth, and when the child's deciduous teeth have not fallen off and new teeth grow next to them, double-layered teeth will appear. "Double-layer teeth" are not harmful, which will not only limit the normal development of children's jaws, but also affect the occlusion of upper and lower teeth, hinder chewing ability, and affect eating, digestion and absorption. Therefore, when children are found to have "double teeth", they should go to the hospital as soon as possible to remove deciduous teeth and give up the normal position of permanent teeth growth.
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 and other reasons, parents should also ask a doctor to make a retainer as soon as possible to ensure that the gap between them will not be narrowed, laying a good foundation for the normal growth of permanent teeth.
Frequently asked questions about tooth replacement;
Most children begin to change their teeth at the age of five or six, as early as four. Some children will lose their first deciduous teeth at the age of seven, which is caused by individual differences of children, so parents don't have to worry. Generally, tooth loss usually begins with the next two incisors, followed by the upper two incisors.
So, what may happen during the child's tooth change and how to deal with it?
First, tooth delay.
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.
Second, it hurts a little.
The process of tooth loosening and falling off is generally painless, but with the falling off of deciduous teeth, children's "six-year-old teeth" will grow out, which may cause gum swelling and make children 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.
The newly erupted permanent teeth may not be as white as deciduous teeth, but the difference is so subtle that almost no one will notice. Moreover, don't be surprised that children's new "big teeth" look incongruous with their faces, because their heads will continue to develop and their permanent teeth will not grow again.
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.
Third, changing teeth: What's wrong with being too early or too late?
Premature delivery: Generally, children'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, which may be systemic or just local oral reasons, such as metabolic disorder or periodontal disease.
Too late: 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 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.
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.
Fourthly, the crowding of deciduous teeth will cause the problem of permanent teeth arrangement.
Generally speaking, the reason for the crowding of 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, so whether permanent teeth are crowded or not is related to the space between deciduous teeth. 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.
5. How long does it take for the teeth to loosen and finally fall off?
The time for deciduous teeth to fall off is not fixed, which depends on the absorption degree of deciduous teeth roots when permanent teeth erupt, and some also depend on the position of permanent teeth or whether 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 can't wait for their permanent teeth to come out before their primary teeth fall off, resulting in two rows of teeth. This is not a rare phenomenon, but a "double tooth" phenomenon that often occurs when children change their 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.
