The order of children's tooth changing period is: children are about 6 years old, near the back of the last deciduous molar.
The first permanent molar, also called the sixth molar; Earlier or at the same time as the lower central incisor, the lower central incisor fell off at the age of 6, the upper central incisor fell off at the age of 7-8 and the lower central incisor fell off at the age of 7-8. 8-9-year-old deciduous upper incisors fall off and grow permanent upper incisors; At the age of 9- 12, the first and second deciduous molars fell off, and the first and second pairs of canines grew. 10 ~ 12 years old, deciduous teeth fall off and permanent teeth grow out.
The whole tooth changing period is an important period for children to protect their teeth.
First of all, the earliest eruption of the first permanent molar, that is, the six-year-old molar, plays a role in positioning and setting the height of the child's maxillofacial region, and has an impact on the eruption and orderly arrangement of other teeth. Protecting it can benefit you for life.
Secondly, attention should be paid to correcting children's bad habits during tooth changing. During the 6-7 years of changing teeth, children usually have bad habits, such as biting their nails, biting their lips, sticking out their tongues and licking their teeth. , can directly affect the dentition, facial development asymmetry, thus leaving a lifelong regret in appearance. Although some permanent teeth have erupted, some deciduous teeth have not fallen off, so they should be removed from the stomatology department. For some stubborn bad habits that you can't correct, you should go to the stomatology department as soon as possible and put on an appliance to help correct them.
Third, 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 age-related diseases of deciduous molars, 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.
Fourth, permanent teeth should be observed and corrected regularly. When changing teeth, the anterior permanent teeth erupt under 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.
Fifth, educate children in tooth changing period to pay special attention to dental care. When changing teeth, teeth are irregularly arranged, permanent teeth erupt and deciduous teeth stay, resulting in double rows of teeth. At this time, if you eat more food containing sucrose and don't pay attention to oral hygiene, it will lead to poor tooth cleaning and food retention, which will easily lead to dental caries of deciduous teeth and permanent teeth.
Therefore, at this time, we should pay attention to educating children to brush their teeth carefully and eat more foods containing fiber, which will help children clean their teeth and promote the growth and development of jaws and maxillofacial regions.
