Will there be no more tooth decay after the fluoride and fossilization?

  The following will introduce to you that after fluoride and fossilization, no more caries will grow? This will take you about two to three minutes to browse, thank you for reading:

What is fluoride application? What is fissure closure?


Fluoride application, also known as "topical fluoride", is a relatively high concentration of fluoride applied to the surface of the teeth by a doctor to enhance the ability of the teeth to prevent caries. Nowadays, there are mainly two ways of fluoride application in China, namely fluoride foam and fluoride varnish. Fluoride foam is to make fluoride in the form of foam and squeeze it into the tray by the doctor; the child bites the tray and the fluoride can effectively penetrate into the tooth. The fluoride protective varnish, on the other hand, is more concentrated than the fluoride foam and is applied to the tooth surface by the doctor, which can also effectively prevent tooth decay.


Vulgarization is very effective for the prevention of dental caries in both milk teeth and permanent teeth. So what is a sulcus? We can all feel that the molar teeth, which are located at the back of the teeth, have uneven surfaces. This is because the teeth, especially the molars, are formed by the fusion of several cusps, and the intersection of the fused cusps is the "sulcus area". The sulcus area is particularly prone to food residue and plaque formation, but the toothbrush cannot brush the plaque in the sulcus. Therefore, regardless of whether it is a milk tooth or a permanent tooth, the sulcus is the part that is easy to be decayed. To seal the sulcus, after the tooth surface is cleaned, a layer of polymer resin material is applied to the sulcus to seal the sulcus, so that the food residue can no longer enter the sulcus, blocking the nutrient source of cariogenic bacteria in the sulcus, and effectively preventing tooth decay.




How old can my child be for fluoride application? When should a child not be fluoridated?


In some areas of China, free fluoride application service is available for preschool children. Children over 3 years old who can cooperate with the doctor can enjoy full mouth fluoride application service with the informed consent of parents. If the child is allergic, or during a cold, fever, or oral rupture, inform the doctor in advance and the doctor will assess whether the child can receive fluoride according to the situation. It is important to note that whether the fluoride foam or fluoride protective varnish is applied, it needs to be done by a professional dentist and cannot be done at home by yourself. For children under 3 years old, free fluoride application service is not available. Parents can bring their children to the hospital for examination, and the doctor will determine whether the child needs fluoride application based on the results of the oral examination.








How long does a fluoride application last? How long does the fluoride application take?


Generally, it is enough to apply fluoride once every six months. However, if the child has more caries in milk teeth, after curing the caries, it is recommended to go to the hospital once every 3 months for examination and fluoride application. For children who are prone to caries, the number of fluoride application can be increased appropriately. The operation time required for fluoride application is not long, the fluoride foam only takes 4 minutes and the child's cooperation is high.




Is it safe to apply fluoride? Can it cause dental fluorosis?

 Fluoride is relatively safe, but only the intake of fluoride in excess of the safe dose can cause harm to the teeth and body. Dental fluorosis is a condition in which a child consumes too much fluoride before the age of 7, resulting in "fluoride spots" on the permanent teeth that erupt after the age of 7. Research has proven that topical fluoride is safe and effective and does not cause dental fluorosis or excessive fluoride absorption.





Can both baby and permanent teeth be sealed? How old can a child be for a sealant?


Whether it is a baby tooth or a permanent tooth, as long as the sockets are deep and there is a possibility of decay, the sockets can be closed. If the child is able to cooperate with the dentist between the ages of 3 and 4 years old and the sockets are deep, we recommend the child to have the sockets of the baby teeth closed. First permanent molars begin to erupt at the age of 6 years and when they are fully erupted, they can have their sockets closed. Usually, the appropriate age for the first permanent molars to have their sockets closed is between 7 and 9 years old, and they can be examined at the age of 6. The second permanent molars usually erupt around 12 years old, and the appropriate age for sockets closure is between 12 and 14 years old. Parents should regularly take their children for oral checkups, some children have early teething, as long as they are fully erupted, they can do it if they meet the indications for doing the fissure closure.





Can I have a cavity sealant for a decayed tooth or a filled tooth?


In principle, we do not do it for decayed or filled teeth, but for intact teeth. Tooth that has been filled needs to be checked and evaluated by the doctor to see if there is still a deep sulcus before deciding whether the sulcus can be closed. There are several tooth surfaces, if the occlusal surface is decayed, but there is still a deep sulcus on the side, the sulcus on the side can be closed.




Do I need to have regular fissure closure? Is it necessary to have fissure closure beyond the age of fissure closure?


The effect of fossa closure is related to the retention time of the sealant, the longer the retention time of the sealant, the better the effect of caries prevention. The sealant is most likely to fall off within half a year, so we need to review it after half a year to see if the sealant is still there, if it falls off, we need to make it up in time. If the suitable age for the closure of the sulcus is exceeded, but the sulcus is still deep, you can still do the closure of the sulcus to prevent the occurrence of dental caries.


Is it better to do fluoride application and gully closure together to prevent tooth decay?


Fossa closure and topical fluoride are two kinds of caries prevention measures, which can be carried out at the same time, and the doctor needs to formulate the corresponding treatment measures according to the examination results. If the sulcus is deep, it is necessary to do sulcus closure; if the child has a high possibility of caries, it is also possible to do fluoride at the same time with sulcus closure.




Does having a fissure seal and fluoride prevent tooth decay?


After these two measures, it is necessary to brush the teeth carefully to prevent tooth decay. The sealant of the gutter closure will be worn out as the child grows, but the research shows that the possibility of tooth decay is greatly reduced for the teeth with gutter closure compared with those without it, and even if the teeth with gutter closure suffer from tooth decay, the degree of decay is much lighter than those without it.





What is the best way to prevent children from getting tooth decay?


The best way to prevent children from getting caries is for parents to reserve good health knowledge and give children good oral hygiene habits: parents feed children scientifically, clean children's mouth, take children to consult professional dentists to evaluate children's oral health condition as soon as possible after children's first teeth erupt, and cooperate with fluoride toothpaste and give children local fluoride coating and sulcus closure in time, so as to keep children away from caries.
