Chronic fluorosis will first affect the baby's tooth development, making the teeth rough and dull, and spots and stripes appear on the tooth surface, which is yellow and forms dental fluorosis. Once dental fluorosis is formed, it can never be recovered.

Be alert: children with chronic fluorosis!

Dried fish is made of marine fish, which is not only rich in nutrients such as protein, calcium and phosphorus, but also delicious. According to the determination, the fluorine in fish fillets is more than 2,400 times that of cattle, sheep and pork, and more than 4,800 times that of fruits and vegetables. However, the daily physiological requirement of human body for fluoride is only 1 ~ 1.5 mg. If you ingest more than 4 ~ 6 mg of fluorine from food every day, fluorine will accumulate in the body and cause chronic fluorosis over time. Therefore, children should eat less fish fillets.

Can children use fluoride toothpaste?

Fluorine is an essential trace element for normal metabolism and normal development of teeth and bones. Appropriate fluoride supplementation is a very important preventive measure in childhood, which has a good caries prevention effect in the process of enamel formation and mineralization. Because human milk or milk contains only a very small amount of fluoride, children living in low fluoride areas and caries-prone areas should be supplemented with fluoride from 6 months after birth. Fluoride drops are the main way for children to supplement fluoride. Children aged 3-6 can use fluoride tablets, but excessive fluoride will do some harm to their health. Therefore, the supplementary doses of fluoride tablets and fluoride drops should be prescribed by dentists and subject to the guidance and supervision of oral preventive health professionals.

Children can use fluoride toothpaste, which is one of the local methods to prevent dental caries by using fluoride. However, too young children may accidentally take and swallow fluoride toothpaste during brushing. It is suggested that children under 6 years old should use fluoride toothpaste under the supervision and guidance of their parents, and apply a small amount each time, about the size of soybean grains or about 5mm of toothpaste. In areas with high fluoride content in drinking water and endemic fluorosis, fluoride toothpaste is not recommended for children under 7 years old.
