AIUI, that is correct.

Acute ingestion would be rather perilous to the organism. And that is
exactly why the ingredient for common rat poison is NaF. That and the
fact that NaF is odorless.
Chronic ingestion is another matter altogether. And there is the issue
of of age and dose-dependent result, which then brings the questions
of actual results of fluoride ingestion by different types of
The total amount of fluoride ingested by any arbitrary individual
cannot by controlled by water fluoridation. AISB.

The patient is not only uninformed of the drugging -- and again, its
not a nutrient but a toxic drug -- he is never monitored for side
effects of the regiment. Not only is the patient unmonitored for
long-term side effects, no patient has ever been.
We've seen in history the situation with TEL (tetraethyly lead), an
anti-knock additive. For years, that was considered to be safe, like
fluoride, and for years, we were told that there was no proof that it
was harmful in "small" amounts, all by the big companies General
Motors, DuPont Corp. Standard Oil and Charles Kettering.
Kettering is also implicated in the promotion of water fluoridation.

And worthwhile of discussion, even if top-posted.
Late for class now..
