Fossa sealing at the age of 8 is mainly for the eruption of the first permanent molar and molar teeth, depending on the development of the teeth.
1. Regarding fossa sealing, it is mainly for permanent molars. 8-year-old children have already erupted their first permanent molars, and in order to prevent the teeth from decaying, it is usually required for each permanent molar, but it must be required in the absence of caries. In addition, because the milk molar teeth have a long time to replace, milk molar teeth also need to be fossa sealing.
2. The operation of fissure sealing is also relatively simple, applying fluoride directly to the surface of the teeth, or using silver ammonium fluoride, which can effectively stop tooth decay and prevent the formation of cavities.
If you need to do fossa sealing, it is recommended that you take your child to the hospital for examination first, and the doctor will selectively do fossa sealing according to individual conditions. For those who do not meet the conditions, scraping is needed first to scrape away the decayed tissues so as not to aggravate the degree of dental caries.
