What are the safe levels of fluoride?
Levels below 2 milligrams per liter are considered safe and beneficial to teeth and bones. A secondary standard for fluoride has been set by the Environmental Protection Agency (EPA) at 2 milligrams per liter to protect consumers against dental fluorosis.

The EPA has set standards for public water supplies for fluoride at 4 milligrams per liter. Some individuals that consume water in excess of 4 milligrams per liter over many years could get bone disease, which can include pain and tenderness of the bones.
