Can you tell me the health concerns for having fluoride in the drinking water?
<|assistant|>
The health concerns of consuming fluoride in drinking water include increased risk of hypothyroidism, increased chance of developing kidney disease, increased chance of developing certain bone and teeth disorders and an increased chance of developing a dental fluorosis. In addition, high levels of fluoride have been linked to brain damage and other neurological problems. 
 
Furthermore, excess exposure to fluoride, in addition to having adverse effects on the health of those ingesting it, may also lead to environmental and biological damage. Excessive fluoride exposure has been linked to increased rates of aphthous ulcers, lowered intelligence, and thyroid dysfunction. In severe cases, fluoride poisoning may be lethal.
