When a child reaches a certain age, they begin to change their teeth. When changing teeth, there are many problems that need to be paid attention to in order to better maintain oral health and allow teeth to grow. There are many things you need to pay attention to during the tooth replacement process, and you need to know in advance. So what is the sequence of children's teeth replacement, and what are the precautions for children's teeth replacement? Let's take a look.

Children's tooth replacement start time

Teeth replacement in children generally starts around the age of 6. The physical loss of the first deciduous tooth mostly occurs around the age of 6, but it also occurs as early as the age of 4, or as late as the age of 7-8, so don't worry. Baby teeth that fall out naturally have no roots, and the shedding surface takes the form of nibbling. Parents should pay attention to observation, not to be confused with deciduous teeth.

The order of children's teeth replacement

When it is time for children to change teeth, parents can know which tooth grows first and whether deciduous teeth fall out through the sequence of children's teeth replacement.

Under normal circumstances, children's teeth are replaced according to the principle of symmetrical upper and lower rows of teeth, first lower and upper. The order of teeth replacement for children is as follows:

1. When the child is 6-8 years old, the first permanent tooth begins to grow, that is, the central incisor, and the first molar also grows slowly;

2. Lateral incisors begin to grow when the child is 8-9 years old;

3. The bicuspid teeth of children aged 10-12 begin to grow, and the first bicuspid tooth will grow first, that is, next to the lateral teeth;

4. When the child is 11-12 years old, the upper and lower fangs have gradually grown;

5. Children aged 12-13 begin to grow second molars;

6. The last third molar, the wisdom tooth, does not start to grow until the child is 17 years old, and the time to maintain growth is 21 years old, which varies from person to person.

Precautions when children change their teeth

1. Always pay attention to the development of teeth

Always pay attention to the growth of your child's deciduous and permanent teeth, and take your child to the dentist regularly, so that problems can be found at any time and resolved as soon as possible. If the tooth does not fall out, the tooth starts to loosen from the root until it actually falls out, which usually lasts for a few months, and it will fall out on its own if you are not careful, such as when you eat. But there are also teeth tied together like threads that never fall out and may interfere with chewing. In this case, you can have your child try to turn it. If the root is completely detached, it will fall off with a little twist. Never use force, let alone yank, because if the root is only half off, it will be pulled. The consequences can easily lead to injury and infection.

2. Eat more chewy food

When a child is about six or seven years old, permanent teeth begin to grow in, replacing the original deciduous teeth. Although some children's permanent teeth have already erupted, the deciduous teeth are often unwilling to "give in", forcing the permanent teeth to grow from the inside of the deciduous teeth, forming "double teeth", resulting in irregular arrangements of the permanent teeth. There are many reasons for the retention and loss of baby teeth. The most common is that the child eats too finely and does not give full play to the physiological stimulation of the teeth. The main function of teeth is to chew food, and chewing food can promote the growth, development and loss of the roots of deciduous teeth. Therefore, as the child grows older, the child should be allowed to eat more chewy food to maintain a good stimulating effect on the deciduous teeth and promote the deciduous teeth to fall off on time. When the child's incisors and back molars grow, you can add some corn, apples and other foods to make the tooth change completed smoothly.

3. Pay attention to correcting children's bad habits

During the period of tooth replacement, deciduous teeth and permanent teeth coexist, and the permanent teeth have just erupted, especially the "six-year-old teeth", which are "the key to occlusion". They are bulky and have many pits and grooves on the occlusal surface that are prone to trapping food scraps. In addition, most children do not brush their teeth thoroughly, and tooth decay is often prone to occur. The most important thing at this time is to teach children how to brush their teeth properly. During tooth replacement, when the deciduous teeth are loose and about to fall out, the child often licks the loose teeth with the tongue, or sticks out the tongue, bites the tongue, bites the finger or pencil, and licks the teeth with the tongue. These bad habits will affect the growth of children's teeth, lead to tooth deformation, will affect the normal eruption of permanent teeth, and should be corrected in time.

4. Protection of permanent molars

In particular, it is necessary to protect the first permanent molars that grow around the age of 6-six-year-old molars, because it has the effect of positioning and setting the height of the whole mouth, it has a great impact on the development of the lower jaw and face of children, and has a great impact on other permanent The eruption and alignment of teeth also play an important role. If the child has reached the age of changing teeth, and the permanent teeth have not yet erupted, take the child to the hospital for examination in time to obtain the help of the doctor, and it is normal for the permanent teeth to be slightly crowded and twisted.

5. Develop a good habit of brushing your teeth

It is necessary to urge children to brush their teeth every day. It is best to have an adult help brush their teeth at night before going to bed, especially the upper teeth are more difficult to clean and are most likely to cause dental caries. There are also six-year-old molars that are difficult to brush, because they are in the innermost part of the mouth, so use toothpaste and toothbrushes specially designed for children. In addition to brushing their teeth, it's a good idea to rinse your child's mouth after every meal to maintain oral hygiene.
