How much fluoride is in the body?

Total fluoride in bone tissue is 2.5 g, in enamel is only 0.1 g. In the enamel, fluorine is contained in the form of crystals of fluorapatite - Ca5F( PO4) 3.In the enamel, hydroxyapatite crystals predominate, but upon interaction with fluorine the hydroxyl group is replaced by a fluorine ion, resulting in the formation of a "stable fluoride" - fluorouppatite. What is the difference? Fluorapapatite is several times stronger and more stable , less soluble. The more fluorampatia, the stronger the enamel.

Positive action of fluoride

  1. Forms a "labile" calcium fluoride on the surface of the tooth, which protects the enamel when exposed to acids;

  2. Suppresses the life of bacteria;

  3. Slows down the cleavage of simple carbohydrates - worsens the nutrition of harmful bacteria;

  4. Prevents the attachment of bacteria to the surface of the enamel and gums - additional prevention of caries;

  5. Strengthens microcirculation in the salivary glands - enough saliva is produced, enriched with calcium ions;

  6. Strengthens local immunity( by activating macrophages);

  7. Bactericidal, bacteriostatic action;

  8. Microdoses of fluoride positively affect the biological state of the organism, normalize protein and mineral metabolism.

Fluorine as a chemical element is indispensable for human health.

Who is harmful to fluoride?

In Russia, the fluorine content in different sources of water is not the same. In areas where the fluoride concentration of is more than 1 mg / liter , people develop diseases such as fluorosis and caries. To such people reception of fluorine is counter-indicative, since.acts destructively. Conversely, in regions where fluoride in water is not enough - less than 0.5 mg / liter , there is also a high incidence of caries, gingivitis, periodontitis.

Ideal fluoride concentration

Optimum concentration of fluoride 1,0-1,2mg / liter of drinking water is considered optimal.

Drinking water in Russia

Note the fluorine content in water: at low concentrations, fluoride is recommended to be taken additionally, at high concentrations - avoid exposure to fluorine pastes, try to drink bottled water without fluoride.
