Can you tell me the health concerns for having fluoride in the drinking water?

The health concerns of having fluoride in the drinking water involve both beneficial and adverse effects. Fluoride is considered beneficial in reducing tooth decay when consumed in optimal levels. In excess, however, fluoride can cause teeth to be more prone to staining, lead to skeletal fluorosis, and even impact the brain and nervous system. Additionally, fluoride can affect kidney disease and diabetics and can interfere with other pharmaceuticals or nutritional supplements, such as vitamins and minerals.
