Is water pollution a cause for dental fluorosis?

No: Fluorosis is caused by a high concentration of Fluoride in one's water supply.

No: In agreement with dr stoval. It is abnormally high natural flouride concentrations in the drinking water, ingested for a long time, that cause flourosis.

Fluorosis: Dental fluorosis is a result of too much Fluoride in the diet, typically coming from water in areas that have very high naturally occurring fluoride. This can be adjusted by municipal water treatment plants. Water pollution has many other hazards, but too much Fluoride is seldom one of those risks. If you are on well water then it might be wise to have the Fluoride level tested by lab.

Definitely, no: Only a child may get the enamel fluorosis if he or she gets too much fluoride during the years of tooth development. It is irrelevant if water is polluted.
