I'll ask you "Fluoride or not"

Some scientific knowledge about fluorine!

Fluorine is a chemical element with the symbol F and atomic number 9. It is a pale yellow gas with a strong pungent odor. Fluorine is widely present in nature, mainly in the form of fluoride in rocks, soil, water and air.

The role of fluoride:

1. Enhance the acid resistance of teeth: Fluoride can combine with the minerals in the teeth to form a hard protective layer of fluoroapatite, thereby enhancing the acid resistance of teeth and preventing the occurrence of caries.
2. Promote bone health: Fluoride can promote bone growth and development, enhance bone density and strength, and prevent the occurrence of osteoporosis.
3. Prevent water fluoride disease: In some areas, the fluoride content in the water is too high, which can lead to the occurrence of water fluoride disease. Fluoride can combine with calcium, magnesium and other ions in the water to form insoluble fluoride, thereby reducing the fluoride content in the water and preventing the occurrence of water fluoride disease. 

How to use fluoride correctly:

1. Use fluoride toothpaste: fluoride toothpaste is one of the effective ways to prevent tooth decay. When using fluoride toothpaste, pay attention to the correct brushing method, squeeze the toothpaste on the toothbrush, brush your teeth gently, and do not use too much force to avoid damaging the teeth and gums.
2. Drink the right amount of water: In some areas, too high or too low fluoride content in water can cause health hazards. Drinking the right amount of water can maintain the body's water balance and also avoid excessive fluoride intake.
3. Reasonable diet: Some foods are rich in fluoride, such as seafood, tea, milk, etc. A reasonable diet can intake an appropriate amount of fluoride, but can also avoid excessive intake of fluoride.
