Prevention of dental caries should start in early childhood. From the baby’s upper and lower milk incisors eruption to 20 milk teeth gradually grow, should pay attention to the prevention of dental caries. The good or bad of the child’s teeth is closely related to the parents’ protective awareness of dental caries. Nowadays, changes in eating habits, food is too soft, too fine, sticky, food or sugar is easy to stay in the child’s milk incisors teeth and large and small milk molar occlusal surface of the fossa, fissure, teeth. Therefore, children should be allowed to drink some water or learn to rinse their mouths after eating and make it a habit. Young children’s incisors can be fine soft gauze dipped in light salt water to wipe the surface of the teeth; 1 year and a half – 2 years old children with large and small molar teeth gradually eruption, you can teach children to learn to brush their teeth. Because the surface of the child’s milk teeth and young permanent teeth are often attached to a layer of bacteria and saliva by a mixture of protein film, medically known as plaque. Rinsing and brushing can reduce and continuously remove this plaque and reduce the occurrence of dental caries. After the eruption of milk teeth, you should often give your child some tender vegetable hearts, because vegetable food contains more fiber, rougher food not only helps children’s overall nutritional intake, but also prevents dental caries and is conducive to oral hygiene. Expert research has found that too much candy and snacking for children is not only bad for the stomach and intestines, but also bad for the milk teeth. To avoid eating candy before bedtime, especially do not sleep with candy. What medical measures are available for early prevention of dental caries? First, fluoride caries prevention This is a kind of caries prevention measures to enhance the teeth’s ability to resist caries. Fluoride has an inhibitory effect on acid-producing bacteria and caries-causing streptococci. In areas without running water and lack of fluoride, fluoride can be added to the water source under the guidance of the local health department; the use of fluoride toothpaste can also reduce the caries-causing streptococcus and lower the incidence of dental caries. Topical application of low concentration (1%-2% NAF) sodium fluoride solution. Regularly (4 times a year), dentists can be asked to apply 2% sodium fluoride solution, 75% sodium fluoride glycerin paste or use other fluoride drugs to prevent caries, such as fluoride gel, acid phosphate fluoride gel, ADFI anti-caries gel, etc., to prevent and treat caries. Fissure closure therapy against caries This is a comprehensive treatment anti-caries technology combining synthetic polymer materials and acid etching technology, and it is also a more effective anti-caries treatment technology in recent years. It is suitable for the occlusal surface of children’s large and small molar teeth and young permanent teeth, especially for the closure treatment of molar teeth in the grooves, nests and fissures which have the tendency to suffer from caries. Generally, 3-4 years old is appropriate; the fossa sealing treatment of young permanent teeth is appropriate at the age of 6-7 years old; the upper and lower mandibular molar and the second molar are usually closed at the age of 12 years old or so is appropriate. The general principle of technical operation is that the fossa and fissure of milk molar and young permanent teeth should be sufficiently dehydrated and dried after treatment by acid etching technology, and then closed up tightly with synthetic polymer material in time. This treatment is more effective in preventing the occurrence of dental caries. After the fissure sealing treatment, you should still have regular checkups or ask your doctor to review the treatment. If the sealant (milky-white resin-like material) falls off, you should ask your doctor to perform the sealing treatment again. Fillings for shallow cavities in the fossa and adjacent teeth When cavities of about 1-2 mm have appeared in the fossa, fissure or adjacent teeth of the child’s milk molar and young permanent teeth, the traditional and reliable filling method (commonly known as filling) should be used to fill the cavities. In particular, the large and small molar teeth and young permanent teeth in the back of the child should preferably be treated with fillings made of silver amalgam material. The main points are to remove the carious tissues, to protect the pulp (nerve), to make a good fixed, force-resistant cavity (especially in young permanent teeth), and to fill the cavity in a timely manner after disinfection, dehydration, and adequate drying. In areas that do not have standardized medical treatment or if the child is unable to cooperate with the treatment, composite resin-based filling materials or glass ionomer-based filling materials can also be used for filling. After caries filling treatment, parents should always observe or ask the doctor to review the treatment under good light conditions, and if it is found that there is a tendency of caries change at the edge of the filling, the filling treatment should be redone again. The restorative and filling treatment of caries, especially the treatment of caries occurring on the neighboring surfaces of teeth, is quite difficult and requires close cooperation between parents and children. In medically developed areas, treatment can be provided by experienced dentists or pediatric dentists. Early detection and early treatment, twice the result with half the effort! Both reduce pain, but also reduce the economic costs. Caring for your child’s teeth is caring for your child’s health, and it’s a lifetime of health.
