Heard this in a lecture. I do not keep reference studies in the back
of my head.
If you are looking for that data talk to the researchers.

Wrong. This exchange is now limited to outer enamel not miniralization
of dentin inside the tooth which is where caries spreads.

Hydroxyapatite is a good ion exchanger.
There is more in a tooth than hydroxyapatite.

Well not exactly NADA.

F ionic bond is much stonger than OH bond in an acidic environment
such as a periodontal pocket with a flora of bacteria or within
infected dentinal tubules by strep mutans.
That is the basis for ozone treatment for reminerization of dentin.

Discussed???? This is now recommended preventative therapy for post
menopausal women for osteoporosis.

OK Duration of exposure is directly related to quantity over time
however this quantity can not be compared to acute toxicity as
observed by injecting large amounts of fluoride.

Individual susceptibility is not a major factor here to absorbtion of
F into bones and teeth from ingestion.
