Children's tooth changing process

In the process of changing children's teeth, we will have two pairs of teeth in our life. As we all know, children's teeth change starts at about 6 years old, and our parents must take the baby's teeth and oral problems seriously. The following is the sharing of children's tooth changing process.

Children's tooth changing process 1 usually starts to erupt at the age of 6 1 permanent teeth, which are medically called "six-age teeth". Since then, deciduous teeth have been falling off and permanent teeth have erupted one after another.

◇6 years old: two lower incisors, the first molar behind the second deciduous molar, one on the top, one on the bottom, one on the left and right; The front teeth of the next two deciduous teeth fell off.

◇7 years old: two upper incisors and two upper deciduous incisors fell off.

◇8 years old: upper and lower incisors, upper and lower deciduous incisors fall off.

◇9- 10 years old: lower fangs and the first pair of fangs (one for the upper, lower, left and right),

The lower deciduous canine and the first deciduous molar (upper one, lower one, left one and right one) fell off.

◇ 10-ll years old: upper canines come out and upper deciduous canines fall off (one on the left and one on the right).

◇ll- 12 years old: the upper and lower second pair of canines (one left and one right) came out, and the upper and lower third deciduous molars fell off (one left and one right).

◇ 12- 13 years old: all deciduous teeth fall off, and only permanent teeth are molars in the future.

(12 years old as the second molar, 18 years old as the third molar, once every six years, hence the name 6-year-old tooth, but this tooth was not until about 30 years old, and some did not. )

The number of teeth in the tooth position and the time for changing teeth.

Four central incisors 6-7 years old.

4 lateral incisors 8-9 years old

The first pair of fangs is 4 10 years old.

Four single teeth 1 1 year

The second pair of tusks 12 years old.

Four first molars, 6 years old.

Four second molars 13 years old

The process of changing children's teeth 2 The process of deciduous teeth falling off and permanent teeth growing is called the period of changing children's teeth. Under normal circumstances, there will be corresponding permanent tooth germs under the root of deciduous teeth. Children's deciduous teeth generally begin to fall off at the age of 6. However, because everyone's physique is different, some children will start changing their teeth in advance, and some children will start changing their teeth later. Therefore, the time to start replacing one's primary teeth is about 4 to 8 years old, and it is usually changed from 12 to 13 years old.

Under normal circumstances, children's tooth replacement is the standard of loosening first and then lifting. The order of children's tooth change is as follows: the first new tooth, the central incisor, begins to grow when children are 6-8 years old; When the child grows to 8-9 years old, he begins to grow lateral incisors;

10- 12 years old children began to grow bicuspids, and the first bicuspids grew around the lateral teeth; When the child is 1 1- 12 years old, the left and right rows of teeth will slowly grow out; 12- 13 years old children began to grow second molars; The last third molar, that is, wisdom tooth, will not grow until after 17 years old, and it will grow until about 2 1 year old.

Because children change their teeth for a long time, many children may have fear when they change their teeth for the first time, so parents need to tell their children that changing their teeth is a normal physiological state and a process that everyone will experience. Don't be too alarmed.

When children change their teeth, it is recommended to take them to the stomatological hospital to take panoramic photos of their oral cavity. See if there are any extra teeth or congenital missing teeth. If so, it is recommended to see a doctor as soon as possible to determine the treatment plan.

When a child changes teeth, if the deciduous teeth have not fallen off and the permanent teeth have erupted, the deciduous teeth must be pulled out in time to avoid uneven dentition of the permanent teeth.

Parents should supervise their children to maintain oral hygiene during tooth replacement. Brush your teeth regularly and clean your teeth every day. Because there are many gaps in children's teeth, the permanent teeth and deciduous teeth in the mouth are staggered, which is easy to leave food residue in the gaps. If you don't brush your teeth correctly during tooth changing, it is very likely that the newly erupted permanent teeth will be decayed.

Children should have a light diet during tooth changing, and eat little or no irritating food to avoid gum inflammation and affect tooth growth. Children's teeth and bones are most prone to calcium deficiency during the critical period of development, so attention should be paid to timely calcium supplementation; Also pay attention to balanced nutrition. If children are picky eaters, parents need to urge them to correct them in time, so that balanced nutrition can make teeth develop better. In addition, give children less sugar. Eating too much sugar can easily lead to tooth decay.

Children's tooth changing process 3 What is the reason for children's late tooth changing?

How many teeth does the child change?

All 20 deciduous teeth should be replaced, and all 20 deciduous teeth should be replaced. Children begin to sprout deciduous teeth from about 6 months old, and from mandibular front incisors to about 2.5 years old, 20 deciduous teeth will sprout (upper row 65,438+00, lower row 65,438+00); Generally, teeth are changed at the age of six or seven, in the order of deciduous teeth. By the age of 12- 13, all primary teeth were replaced by permanent teeth.

The reason why deciduous teeth don't fall out

There are several situations in which deciduous teeth do not fall off:

First, when changing teeth, new and old teeth coexist, and deciduous teeth should be pulled out. The deciduous teeth have no roots, and the deciduous teeth are eating. After the deciduous teeth are pulled out, the permanent teeth will slowly move to the original position of the deciduous teeth because of the push of the tongue. At this time, if there is enough space, the permanent teeth can grow straight. If we ignore the juxtaposition of primary teeth and permanent teeth, it may lead to irregular tooth arrangement or uneven occlusion, and it is easy to cause tooth decay because of incomplete cleaning.

Second, the serious caries of deciduous molars leads to periapical infection, which leads to the adhesion and retention of deciduous roots. At this time, bad teeth should be repaired and treated as soon as possible.

Third, the position of the permanent tooth embryo is abnormal, and the eruption is abnormal. Permanent teeth will erupt out of position, and the root of deciduous teeth will not be absorbed completely or partially, resulting in retention of deciduous teeth.

Therefore, the baby's deciduous teeth will not fall off during the tooth changing period. Parents should take their children to the hospital for examination in time and ask the dentist to handle it correctly.

What is the reason why children change their teeth late?

Mainly related to individual differences, there is no need to worry too much.

Most children begin to change their teeth when they are five or six years old, as early as around four years old. Some children will delay losing their first deciduous teeth until they are seven years old, which is caused by individual differences of children, so parents need not worry too much.

Whether growth and development are retarded.

It is related to growth retardation, calcium deficiency in children, tooth dysplasia and late tooth replacement.

How to care: For the health of children's gums, mothers should supplement calcium for their children according to their conditions. Eating fish, shrimp, crab and other aquatic products can supplement calcium, drinking milk, soybean milk and other dairy products can also supplement calcium, and drinking Long Mu Zhuanggu Granule, which has the effects of strengthening tendons and bones, regulating stomach and strengthening spleen, can also supplement calcium. While supplementing calcium, mothers should also pay attention to their children's diet. Don't let children eat fine food often, and eat chewy food properly during teething and tooth changing.

Retention of deciduous teeth is a common problem.

Falling off with deciduous teeth is too slow, which is a common problem in oral cavity. Retention of deciduous teeth is harmful to oral cavity. In the later stage, the permanent teeth grow out, but the deciduous teeth do not fall off, which easily leads to tooth cracking and irregular arrangement.

Suggestion: Mothers should pay close attention to their children's gum health, learn more about the reasons why children change their teeth late, and take preventive measures as soon as possible. If the child changes teeth late or the permanent teeth are not in place, the deciduous teeth should be pulled out in time.

So is it too late for deciduous teeth to come out and change their teeth?

Some children's deciduous teeth grow late, and parents worry that their children will change their teeth in the future. Generally speaking, children's deciduous teeth begin to erupt from 6 months to 1 year old, and the time difference is normal within 2 to 3 months, so don't worry too much. However, the time of tooth replacement is not necessarily related to the eruption time of deciduous teeth, but more related to gender and genetic factors.

Of course, pay attention to the fact that children change their teeth too late. If the child has not started to change his teeth after he is 9 years old, he should take the child to the dentist to find out if there are other factors that prevent him from changing his teeth.

It's late to change teeth, so it's recommended to take your child to have a 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 if permanent teeth are bred under the gums for a long time, they can be very strong and can successfully break through the imprisonment of gums.

Suggestion: If the child changes teeth late, the mother should go to the hospital to take an oral X-ray to check the gum condition. If the permanent tooth embryo exists, the child's gums will be healthy and the time for teething will be late.

Children's tooth changing sequence

At the age of 6, the first permanent molar, also known as the six-year-old molar, grew right behind the last deciduous molar.

When the lower central incisors grow out earlier or at the same time, the lower central incisors fall off at the age of 6, and the lower central incisors of permanent teeth grow out;

At the age of 7-8, the upper central incisors of the breast fall off, the upper central incisors of the permanent teeth grow out, the lower central incisors of the breast fall off and the lower central incisors of the permanent teeth grow out;

8-9-year-old deciduous upper incisors fall off and grow permanent upper incisors;

9- 12 years old, the first and second deciduous molars fall off, and the first and second pairs of canines grow out;

10- 12-year-old deciduous teeth fall off and permanent teeth grow out.
