What's wrong with children's sawtooth?

When children are about six years old, they will grow their first permanent molars. These teeth are called six-year molars. They will not be replaced, so they must be cared for regularly, otherwise they will easily cause early caries. The development of teeth involves the fusion of many parts. If the tip of the developing leaf is too long, it will lead to serrated teeth. So what is the matter with children's serrated teeth?

First, what is wrong with children's jagged teeth? This is normal. This is a unique characteristic of the development of new teeth and will grow out after a period of time. But this is not the enamel hypoplasia mentioned by the friend above. Enamel hypoplasia is a disease, which belongs to enamel abnormality and is a disease of abnormal tooth structure. Causes of enamel developmental abnormalities: local, hereditary and systemic (such as congenital syphilis, malnutrition, infectious diseases, etc.) Enamel dysplasia is a reduction in the amount of enamel formation, not a reduction in mineralization quality.

Second, children usually start to change their teeth around the age of 6. The physiological shedding of the first deciduous tooth usually occurs around the age of 6, but it can also occur as early as 4 years old, or as late as 7-8 years old, so there is no need to worry. Naturally fallen deciduous teeth have no roots and the fallen surface appears eroded. Parents should pay attention to observe and not confuse them with broken roots of deciduous teeth. People grow teeth twice in their life, namely deciduous teeth and permanent teeth. There are 20 deciduous teeth, which usually start to erupt around 6 months old and are fully grown at 2-3 years old. There are 28-32 permanent teeth (the number of wisdom teeth is 0-4), which usually start to grow around 6 years old and 28 are fully grown at 12-13 years old (wisdom teeth vary from person to person). Therefore, the tooth replacement period is usually between 6 and 12 years old. There are certain rules for tooth replacement. Simply put, it is a certain time and a certain order, following the principle of "left-right symmetry, first lower and then upper". Left-right symmetry, first lower and then upper refers to teeth with the same name.

Children's tooth replacement period is relatively long, generally taking 6-7 years. During this long period, if children have some bad habits, such as biting lips, licking lips, biting tongue, sticking out tongue, sucking fingers, biting nails, etc., it may cause deformities such as uneven teeth, malocclusion and facial asymmetry, affecting tooth function and facial appearance. Therefore, we should always pay attention to correcting these bad habits of theirs. If you have habits that you cannot correct yourself, you should see a dental specialist as soon as possible and wear braces to help correct them. Pay special attention to the maintenance of your teeth, keep your mouth clean, brush your teeth in the morning and evening, and rinse your mouth after meals. If you have crowded or twisted teeth, large spaces between teeth, or dental diseases such as caries, you should see a doctor promptly.
