These doctors tell you about as much as they can without facing a lawsuit. They have to be careful because SOLVAY has gone after people before who have tried to stop their poisoning of the worlds population through fluoride. ( they hold the monopoly on fluoride ) The head of Bilderberg is a Solvay by birth and his name is Etienne Davignon.
The truth is Fluoride isn't safe at any level and should not be in toothpaste either. Big money and lobbyists have kept the truth from coming out. Listen to the doctors as they explain Flouride is a poison.
If it wasn't why do you think the warning label on fluoride toothpaste warns to contact emergency room / contact poison control center immediately if your child swallows it? It's a poison. So why is in your water, Marty? Duh!!!

Because a child is smaller than an adult, and adult toothpaste has a flouride concentration based on an adult's body mass. Toxicity is basically measured in mg/kg, and since children have less kg, the dose for them is less.
There is also a difference between exposure via mucous membranes (in your mouth when you brush) and through the digestive system, which is FAR more efficent in getting substances into your bloodstream.
The labels are based on overly cautious companies who probably sued when a 2 yr old ate a whole tube of giant toothpaste and got sick. again, think mg/kg and dose location.
As for in water, the dose is so low that you would have to drink 1,000's of gallons in a few minutes to get the mg/kg up to where you would be in trouble.
And how much money is the flouride production business worth?
Soluble fluoride salts, of which sodium fluoride is the most common, are only mildly toxic, although they have resulted in both accidental and suicidal deaths from acute poisoning.[3] The lethal dose for most adult humans is estimated at 5 to 10 g (which is equivalent to 32 to 64 mg/kg elemental fluoride/kg body weight).[
