Fluorine (Fluoride)

Description:Fluoride occurs naturally in soil and water of many areas. This mineral is also used in pest control chemicals. The maintenance of teeth integrity is partially due to the presence of fluorine. The reasoning behind this that fluoride reduces the amount of acid that is formed in the mouth by carbohydrates. The deposition of calcium is also increased when fluoride is present, resulting in stronger bones. There are several forms of this mineral. Sodium fluoride is found (in small amounts) in drinking water, calcium fluoride found in nature, and hydrogen fluoride is simply dangerous. If you live in an area where the water supply already contains fluorine, you have a perfect source. Other sources of fluorine are seafood, cheese, milk, meat, and tea; however, the fluorine is lost in instant teas.

Absorption/Storage:90% of the fluorine ingested is absorbed by the intestine and transported by the circulatory system (bloodstream). The teeth and bones then absorb about half, and the other half is excreted through the urine.

Dosage/Toxicity:The following amounts are suggested: newborns-6 months 0.1-0.5mg, infants 6 months-1 year 0.2-1.0mg, children 1-3 years 0.5-1.5mg, children 4-6 years 1.0-2.5mg, children 7-15 years 1.5-2.5mg, adults 1.5-4.0mg. When taking larger doses, consult a physician. A toxicity of fluoride causes the central nervous system to malfunction. This begins with the eyes and then moves on to other parts of the CNS. Eventually, the rhythm of the heart is messed up causing a heart attack. In large amounts, the teeth may become discolored. Also, during the formation of teeth, fluoride accumulates on the enamel leaving a white chalky substance. The teeth are strong; however, this is not practical due to cosmetic reasons. Other serious problems may arise due to a toxicity. These problems include calcification of the ligaments and tendons and degenerative changes in the kidneys, adrenal glands, heart, liver, and eventually the reproductive organs.

Deficiency:Fluorine deficiencies are uncommon in the U.S. because fluorine is usually found in the water. However, the teeth are poorly developed and caries may result from a deficiency in fluorine.

Common Uses:Fluorine is used in the prevention of tooth decay and gum disorders. Since fluorine is used to help calcium be deposited, this mineral is effective in maintaining bone density and growth. Osteoporosis is also treated with fluoride. The fluoride found in toothpaste kills enzymes that cause tooth decay. Dental treatments involving fluoride gets between the teeth and gums.

Precautions:Consult a physician if pregnant, symptoms of nausea, diarrhea, or dizziness last more than a week, or if new symptoms appear.
