Greetings from the Bluff Park Back Porch, way up yonder on Shades Mountain (1,109′) in Alabama:

Among the problems presented there are also issues with fluoride in Africa and India.

Fluoride (/ˈflʊərd, ˈflɔːr-/)[3] is an inorganic, monatomic anion with the chemical formula F
(also written [F]

), whose salts are typically white or colorless.
Fluoride ions occur on earth in several minerals, particularly fluorite, but are only present in trace quantities in bodies of water in nature.
Many minerals are known, but of paramount commercial importance is fluorite (CaF2), which is roughly 49% fluoride by mass.[4] The soft, colorful mineral is found worldwide.
Yep!  It may be naturally occurring in your drinking water.

The fluoridation of water is known to prevent tooth decay[21][22] and is considered by the U.S. Centers for Disease Control and Prevention as “one of 10 great public health achievements of the 20th century”.[23][24]

Certain groups of US citizens are against fluoridation of drinking water.
