we moved to a rural area in 2005 with clean, but unfluoridated well water. had a son. brushes twice daily for 2 minutes a time like everyone else in the house.

he had an excessive amount of cavities and the dentist did not use any supplementation. This was painful and unnecessary for my son (we stopped using that dentist when it was clear this isn't 'normal').

i realize this is n=1. but apparently calgary [0] also realized this was having an opposite effect as well. (yes i realize this is slightly different than supplementation in the parent article but the supplementation would have saved my kid from unnecessary cavities.)

EDIT: clarity on 'supplementation'

Here in Europe we get our fluoride from our toohpaste. Was your sons toothpaste flourinated?

[fazeirony]

absolutely. but i think there's at least some evidence that lack of appropriate fluoridation is beneficial. certainly in my anecdotal example (ofc, i didn't grow up in this town and every town in the US has wildly different fluoride levels in the municipal water systems).

Nowadays you get way more sugar in, well, all and every product
