Is it obvious that the pit and fissures are sealed or the tooth decay? Don't worry, you may have made these 4 mistakes

Research studies have confirmed that pit and fissure sealing can effectively help children prevent tooth decay. But there are still many parents who find that: Mingming has done pit and fissure sealing for the baby early in the morning, and the tooth still grows. What's going on? Don't worry, the child's tooth decay may be caused by the following 4 situations.

Situation 1: After the pit and fissure sealing is performed, the pit and fissure sealing is not regularly reviewed in the hospital

. The pits and fissures are sealed to prevent cariogenic bacteria and sugar-containing acidic metabolites from accumulating in the pits and fissures, a caries prevention measure that corrodes teeth. So, after the pit and fissure sealing, is there no need to go to the hospital? In fact, even with strict dentistry, the probability of pit and fissure sealants falling off is as high as 5-10% per year. Because the pit and fissure sealant has to come into direct contact with food when chewing, the surface will be worn over time. If you eat hard food frequently, the risk of the sealant falling off will be higher. In addition, if the cooperation of the children is not high, the moisture barrier is not done well when the pits and fissures are sealed, which will cause saliva pollution and increase the risk of the sealant falling off. Therefore, after the pit and fissure sealing, you should go to the hospital for a review every 3 to 6 months. If the sealant is found to be incomplete, it must be repaired in time.

Situation 2: There is no caries in the sealed part of the pit and fissure, but other parts are damaged.

The pit and fissure is sealed, but the deep pit and fissure of the molar is protected. , for other parts of the tooth (such as the exposed occlusal surface, the adjacent surface between the teeth, the lingual surface and the buccal surface, etc.) is not protective. Therefore, in addition to pit and fissure sealing, it is also necessary to regularly apply fluoride to the tooth surface other than the pit and fissure. An appropriate amount of fluoride can not only promote the mineralization of teeth and bones (both inhibiting the demineralization of tooth enamel and promoting the remineralization of demineralized enamel), but also interferes with the metabolic activity of cariogenic bacteria, inhibits bacterial adhesion and acid production, and can effectively Reduce caries rates. Moreover, fluoride penetrates better on smooth tooth surfaces, and if combined with pit and fissure sealing, it can provide ideal protection for the entire tooth. It should be reminded that whether it is pit and fissure sealing or fluoride coating, the protective effect on the adjacent surface is very limited. Therefore, it is necessary to use dental floss regularly to remove the food residue embedded in the adjacent surface (it is difficult to brush with a toothbrush), Do a good job of cleaning adjacent surfaces. In addition to regularly applying fluoride, sealing pits and fissures and using dental floss, parents should also urge their children to brush their teeth with fluoride toothpaste in the morning and evening to keep the mouth clean, and at the same time reduce the intake of high-sugar foods to effectively prevent tooth decay.

Situation 3: The timing of pit and fissure sealing is inappropriate

The timing of pit and fissure sealing should be determined according to the time of the eruption of the child's teeth. Usually, deciduous molars will erupt at the age of 3~4, and the first permanent molars (ie, the 6th-year-old teeth) will erupt at the age of 6-7 years; and the second permanent molars (ie, the one behind the 6th-year-old teeth) will not erupt until the age of 11~13 years old. sprout. Therefore, the timing of pit and fissure sealing should be selected at the three age stages of 3-4, 6-7 and 11-13 years old. It takes about 1.5 years from the eruption of the first permanent molars and the second permanent molars to the complete exposure of the pits and fissures, and the establishment of occlusion between the upper teeth and the lower teeth. Doing it again during exposure can ensure a higher success rate of pit and fissure sealing. If the teeth are only partially erupted, some of the pits and fissures will be covered by the gums. If the pits and fissures are sealed at this time, it is difficult to clean and dry the tooth surface, resulting in the sealant will not stick firmly and easily fall off. Of course, for those children who are prone to tooth decay and have symptoms of tooth decay before the teeth fully erupt, pit and fissure sealing can also be done in advance to protect the teeth with a high risk of caries, and do it again after the teeth fully erupt. The fissures can be closed.

Situation 4: There is no filling after tooth decay, only pit and fissure sealing is done

If the child's pit and fissure has already developed tooth decay, it is usually not recommended to give a cavity. The position is to seal the pit and fissure, but to clean the decayed dentin and fill the tooth as soon as possible. If the cavities are not treated, the pit and fissures are reluctantly sealed, not only the sealant will fall off due to the poor adhesion, but also cover the progress of the cavities. Therefore, once you find that your child has cavities, you must go to the hospital in time to fill up the small cavities, and then seal and protect the pits and grooves without cavities. In short, although pit and fissure sealing is currently recognized as a good method to effectively prevent pit and fissure caries, it is necessary to choose the right time to do pit and fissure sealing according to the child’s tooth eruption and caries. Review regularly.
