Fluorine :

10-20 mg of fluorine in its ionized form is present in the blood. Although not strictly essential, fluoride enhances well-being. Fluoride is found in the bones and teeth. 

Sources:

• Drinking water, tea, salmon and sardine.

Requirement:

• 1-2ppm (since fluorine is absorbed through water it is expressed as ppm).

Absorption and excretion: 

• Easily absorbed from small intestine.
• More than half of the ingested fluoride is excreted through urine and the rest is deposited in bones, where there is accumulation with age.

Functions:

Tooth development and dental health:-

• Fluorine is required in traces for development of teeth.
• Helps in prevention of dental caries.
• Large amounts causes fluorosis involving mottling of the enamel. In these conditions, enamel is stratified and it has dull white patches. Tooth shows brown stains and pits.

Bone development :-

• Promotes bone development. 
• Increases calcium and phosphate retention and prevents old-age osteoporosis. 
• Increased uptake enhances osteoblastic activity, calcium deposition and density of bones. 
• Fluoride is an inhibitor of enolase, blocking this enzyme inhibits glycolysis.
