Sadly, the harmful effects of fluorides not only just alter the aesthetic appearance of teeth but also affect the other body organs.
In aborted human foetuses collected from endemic fluorosis area, it was found that accumulation of fluorides in brain tissue causes disruption of certain neurotransmitters and receptors in nerve cells and also increased numerical density of volume of nerves and undifferentiated neuroblasts.
Trendley Dean, a dentist working for the US Public Service, was studying the harmful effects of fluoride, and in 1950, he demonstrated that fluoride therapy, in small amounts, has obviC...
It forms inorganic and organic compounds called Fluoride.

Summary: Fluoride is an important parameter as far as water quality is concerned.
The guideline of World Health Organization is that 1.5 ppm of fluoride is the desirable upper limit in drinking water and the recommended levels are 0.5 to 0.8 mg/L.
 Also vitamin D helps in the absorption of calcium, which is an ideal antidote for fluoride because of its binding with fluoride to form insoluble complex calcium fluoride.

Objective: To investigate the effect of high-dose fluoride on antioxidant enzyme activities of amniotic fluid and fluoride of serum in rats.
In its comprehensive 2006 report Fluoride
in Drinking Water: A Scientific Review of EPA's Standards, the US National Research Council concluded, "It is apparent that fluorides
have the ability to interfere with the functions of the brain and the body by direct and indirect means." (42)
In the Public Health Command Region-West (PHCR-West) Area of Responsibility, shown in Figure 1, none of the CWSs serving more than 3,300 people that adds fluoride
does so at optimal levels, based on 2013 water quality data reported in annual consumer confidence reports (CCRs).* However, some CCR data appear to be incomplete for CWSs practicing fluoridation.
Objective: In children, excessive ingestion of fluoride
from different sources including bottled drinking water and flavoured beverages or soft drinks can lead to the development of dental fluorosis.
