Sources: Fluoride is found in most city water supplies. Treated drinking water is a source of fluoride and foods and beverages that have been grown in areas where the drinking water has been fluoridated and then used in the manufacture of those products. It is also found in fish and tea.

Functions: Fluoride’s primary function in the human body is to strengthen the bone and it is known to prevent tooth decay. Experts contend that fluoride strengthens the teeth’s enamel by strengthening the mineral composition of the teeth themselves. Once the composition of a tooth is strengthened by fluoride it can then ward off or at least be more resistant to attack from acid accumulation in the mouth. Fluoride intake is ideally begun early in childhood when the formation of teeth and bones is still taking place, therefore strengthening the initial buds for the future. Fluoride is known to aid in strengthening developing bone structure.

Even though it is so important to proper functioning of the human organism, fluoride deficiency does occur but typically only in regions where water that is regularly consumed is not treated with fluoridation. Of more concern with fluoride is excess intake.

Fluoride taking in large quantities over time slowly poisons the human body. Prolonged intake of treated water that contains more than 2 parts fluoride per million (ppm) can lead to discolored, mottled or brownish enamel on the teeth. Extremely high concentrations, over 8 ppm can contribute to bone disorders, kidney, liver and adrenal failure as well as the heart, reproductive system and central nervous system. This is especially dangerous in young children and the elderly.

But it is advisable to consume it with the consultation of a doctor.
