What Are Primary Teeth?

Deciduous teeth (deciduous teech), the first group of human teeth, a total of 20 teeth, upper and lower jaws each 10. There are two dentitions in a person's life. The first dentition is called the deciduous dentition, which consists of 20 deciduous teeth. From the first 6 months of birth, the first deciduous teeth have emerged, and about 20 deciduous teeth have emerged at about 2 1/2 years old. From 6 to 7 years old to 12 to 13 years old, deciduous teeth gradually fell off and were replaced by permanent teeth. Permanent teeth are the second secondary dentition after deciduous teeth are lost. If they are lost due to illness or accidental injury, there will be no replacement.

Basic Information

Chinese name

Baby teeth

Auxiliary pronunciation

Some babies have "leakage" in speech due to missing teeth (especially the incisors of the upper jaw). Not only can they not express their personal ideas clearly, they may also be ridiculed by other children, causing serious damage to the young mind.

2. Good for chewing

In the process of growth and development, the baby needs a lot of high-quality nutrition, and the intake method is almost dependent on the oral cavity. And for deciduous teeth that are responsible for chewing to facilitate digestion and absorption by the body, if some or all of the chewing function is lost due to cavities or other diseases, it will cause the nutritional absorption function to be blocked, affect growth and development, and cause future nutritional disorders or frailty.

3. "Space maintenance" function before permanent tooth growth

Below each deciduous tooth, there is a developing permanent tooth. After the deciduous tooth is lost, the permanent tooth can sprout, replacing the original deciduous tooth. Therefore, it can be said that the deciduous tooth is a space maintainer before the permanent tooth eruption.

4. Harmonious appearance

A baby with a high self-esteem may inferiority to a bad tooth, and dare not speak or laugh, and the face close to the mouth may also be collapsed due to missing teeth, which will affect the appearance of the face. These factors may cause the baby's social fear and directly affect the relationship.

5. Promote normal jaw bone development

The development of deciduous teeth has a decisive influence on the physiological and psychological development of young children. If there are diseases such as tooth decay, they should be treated as soon as possible. Because unilateral tooth lesions can make the baby chew on one side only to avoid pain. For a long time, it may cause facial imbalance. Parents feel distressed, and the baby may not dare to make friends because of inferiority.

1. Because children like to eat soft and sweet foods, such as cakes, biscuits, candy, juice, etc., they are susceptible to dental caries.

2. If the caries of deciduous teeth is not treated in time, it will have some adverse effects on children themselves. First, the occurrence of dental caries will destroy the normal structure of children's teeth.

3. The appearance of cavities often makes children feel pain and plug their teeth as soon as they touch the cavities when eating, so they are afraid to chew and concentrate their strength on the healthy side of the teeth. 4. Long-term asymmetric development of children's jawbone and masticatory muscles, and even cause left-right asymmetry of the face. The carious cavity will be gradually enlarged by bacterial corrosion, which affects the normal development and eruption of permanent teeth, which may cause wrong teeth and deformities.

Drug therapy

The application of medicine to treat dental caries is mainly applicable to the superficial caries with a wide range of caries. The initial caries that have not yet formed a cavities can inhibit the development of dental caries, but can not restore the shape of the teeth.

2. Carious tissue filling method

This is often referred to as fillings. For teeth that have formed a substantial defect, filling is currently the most widely used and effective method, and it is the most commonly used method for treating carious tissue. The filling material is mainly used to fix the filling material on the teeth to restore the defects and functions of the teeth, so as to maintain the shape of the teeth and maintain the integrity of the dentition.
