To a person who is knowledgeable concerning body chemistry and function this is a ludicrous question. To any doctor or dentist or pharmacologist, each of whom has been required to study organic and biochemistry as well as human physiology, this question should seem absurd.
How much poison is dangerous for people knowingly to ingest?
Fluoride is a very dangerous toxic substance. It has the capacity to do serious damage or even to kill.
On every fluoride toothpaste package a standardized warning is posted, warning against ingestion of the toothpaste. The warning reads that if more than the normal amount used for brushing should be swallowed that immediate medical attention should be sought.
How much actual fluoride is this?
On the toothpaste cartons that I have examined, the amount of fluoride ranges from 0.15% to 0.24%.
Thus according to the usual amount of toothpaste promoted by the toothpaste manufacturers, that is, one inch squeezed onto the toothbrush, an amount weighing about 1.5 grams, the total amount of sodium fluoride would be about 3.6 milligrams (0.0036 grams).
If the calculations are made using the lower percentage the amount of fluoride is even less.
In both cases, both higher and lower percentages, the warning is the same, that anything more than this should be considered cause for seeking immediate medical attention.
Now . . .
. . . consider the amount that is commonly added to municipal water supplies:
According to the U.S. Department of Health and Human Services the current standard is 0.7 to 1.2 mg/liter.
The U.S. Department of Health and Human Services also has announced a proposal to reduce this amount to 0.7 mg/liter.
How much water do humans need to consume daily?
According to the Mayo Clinic’s article “Water: How much should you drink every day?”,
“The Institute of Medicine determined that an adequate intake (AI) for men is roughly 3 liters (about 13 cups) of total beverages a day. The AI for women is 2.2 liters (about 9 cups) of total beverages a day. ”
For a man such as myself, who works outdoors, on a hot summer day this consumption is 2 to 3 gallons or 7.57 to 11.36 liters.
Consider the amount of fluoride that the toothpaste warning says is cause for seeking immediate attention. On the carton that lists 0.24% the amount of 3.6 milligrams is the amount. On the carton that lists 0.15% the amount of 2.25 milligrams is the amount. According to the warning, anything exceeding this is cause for seeking immediate medical attention.
For children, the ADHA recommended amount of toothpaste is limited to 0.25 grams or a mere 0.6 milligrams of sodium fluoride.
And how much is the amount of fluoride being added to municipal water?
0.7 to 1.2 milligrams per liter!!!!
This is like telling one’s children to brush their teeth and be sure to swallow it all every time that they brush.
How many parents would do such a thing?
What sort of dentist or doctor or pharmacologist would sign a statement saying that this is safe?
If you would like to see the official list, here it is.
My wife and I will be seeking another dentist, one who does not say that it is a good idea for the city to poison its citizens.
