Then the content of this issue is: Is it necessary for children to do pit and fissure sealing? Listen to me! Then let's take a look!

Is it your child? I like soda water, sweets and desserts, often go to bed without brushing my teeth, and begin to replenish water immediately after brushing my teeth. In short, he tried every means to destroy his teeth!

Indeed, it is difficult for parents to teach their children how to maintain their teeth when they are naughty. Therefore, we must take some precautions in advance to prevent the child's teeth from breaking before being replaced!

Among them, pit and fissure sealing is a very important method to prevent caries, because the surface of human teeth is not completely smooth, but there are many cracks, especially in posterior molars, and the pit and fissure on the surface are deep and complicated. .

When brushing teeth, it is difficult for the bristles of the toothbrush to enter these pits and gaps for cleaning. In addition, the quality of children's brushing is not high, and food residues may remain in these pits and gaps, which may easily lead to tooth decay.

Therefore, pits and cracks have become the high incidence period of tooth decay. For newly erupted but not yet fully developed teeth, sealing these pits and cracks is the best way to prevent tooth decay.

Don't think that your deciduous teeth can be replaced just because they are rotten, so it doesn't matter! The highest-ranking "six-year-old tooth" in the oral cavity is an irreplaceable deciduous tooth. If you ignore the early protection, you will regret it until you have serious dental caries!

In addition, parents should not worry that their children will feel uncomfortable when sealing pits and cracks. The principle of pit sealing is actually very simple. Fill the pits and cracks with polymer resin materials that are harmless to human body. Resin can remain in pits and gaps for a long time after hardening, just like covering teeth with a protective layer to protect enamel from bacteria and metabolites, thus preventing dental caries.

So when should we close the pits and cracks of children of all ages?

Most children's dentists with oral precision say that the three periods of 2 ~ 3 years old, 6 ~ 7 years old and 1 1 ~ 13 years old are suitable for the sealing of dental pits and teeth!

The first method is to close the pits and crevices of newly erupted deciduous teeth when they are 2 ~ 3 years old.

Secondly, at the age of 6 ~ 7, the newly erupted pits and cracks of 6-year-old teeth were closed;

Finally, at the age of 1 1 ~ 13, the pits and fissures after the eruption of the second permanent molar were closed.

The results of the third national oral health epidemiological survey show that the caries rate of primary teeth of 5-year-old children in China is 66%, and the caries rate of permanent teeth of 12-year-old children is also 29%.

More than 90% of children's permanent tooth caries are pit and fissure caries. If we can effectively prevent and control dental caries, the prevalence of dental caries in children and adolescents will be greatly reduced.
