A normal exposure level of fluoridated drinking water is about 2 liters a day. That will expose you to 2 liters of H2O and 1.4 mg of fluoride ions.  Try this experiment if you don’t believe water can be more poisonous than fluoride ions:  Ingest 10 times the normal level of water and fluoride ions for several days.
a) eat enough fluoride toothpaste to ingest 14 mg of fluoride ions a day for a week.
b) drink 20 liters of water a day for a week.
Let me know which of these chemicals is more harmful to your health.

Describe how you would conduct an experiment that would “prove fluoride is safe and effective for [everyone]”.
