Don't mistake "six-year-old teeth" for deciduous teeth.

There are two pairs of teeth in a person's life: primary teeth and permanent teeth. When the child is about 6 years old, the teeth that erupt at the back of the dentition, that is, behind the second deciduous molar, are the first permanent molars, that is, the child's first "lifelong" big teeth. Because the first permanent molar often erupts from the mouth when the child is about 6-7 years old, it is used to being called "six-age tooth".

"Six-year-old teeth are the first permanent teeth to erupt. They will accompany people for a lifetime, so they play a very important role in the mouth. " Director Chen said that because "six-year-old teeth" do not experience the process of deciduous teeth falling off when they erupt, they are often ignored by parents, thinking that deciduous teeth need permanent teeth to be replaced, thus ignoring their dental caries.

Now more than 10 children come to see a doctor every day because of the tooth decay of "six-year-old teeth". Among them, 90% parents didn't know it was a "six-year-old tooth" at all, and they all mistook it for a deciduous tooth. As we all know, severe dental caries may lead to the removal of "six-year-old teeth" and become permanent tooth loss. This will not only greatly reduce the chewing function of children, resulting in malnutrition of children, but also affect the development of jaws.

The "six-year-old tooth" is broken and even affects the appearance.

In fact, there are four "six-age teeth", which are the first "big teeth" on the left and right sides of the upper and lower rows of teeth. It is the strongest in the permanent dentition, with the largest crown, the largest cusp and the widest chewing area, and bears more biting force and chewing function than other permanent teeth.

At the same time, "six-year-old teeth" are located in the middle of the whole dental arch and become the main pillar of the dental arch, which is of great significance for maintaining the normal arrangement of upper and lower teeth, maintaining the correct occlusal relationship and ensuring the normal development of maxillofacial region. The premature shedding of "six-year-old teeth" is likely to cause abnormal development of children's facial bones, which will lead to changes in appearance and irreparable consequences.

The newly erupted "six-year-old tooth" is not very firm, and the unpaved occlusal surface is uneven, and the pit and groove are deep, so it is easy to accumulate food residues and dental plaque, which is not easy to clean, so it is eroded by bacteria and prone to dental caries. The pit and fissure sealing method can fill the pit and fissure with deep occlusal surface before the occurrence of dental caries, so that food residues and dental plaque are not easy to accumulate and the effect of preventing dental caries can be achieved.

As parents, we should also help our children maintain good oral hygiene and develop a good habit of loving their teeth. They should take their children for oral examination regularly. Parents should also teach their children the correct way to brush their teeth: brush 1 time every morning and evening, focusing on cleaning the occlusal and buccal surfaces of "six-aged teeth". Director Chen reminded that some dental caries can only be found by dental instruments. It is best for parents to take their children for an oral examination every winter and summer vacation to find and treat tooth decay in time, so that children can have healthy and good teeth.
