Ok, so I was interested in https://fourthievesvinegar.org/tooth-seal/ Was happy that they say it's completely safe but... there's no linked study that proves it's safe. On what basis is it safe?

There's been multiple recent studies linking higher fluoride amount with reduced intelligence in children. How is that different?



fwiw - if you click through to the complete instructions PDF they do link to multiple different studies on the topic: https://fourthievesvinegar.org/wp-content/uploads/2024/09/to...


I don't believe you are supposed to ingest the tooth sealant.


Well yes and they do mention you shouldn't leak it but given that it's on your teeth, how much leaches? Given that it degrades over a year


The fluoride added to the drinking water in the US exposes you to many more times than using a fluoride tooth paste, so any leeching from this is likely inconsequential. There's also papers linked in the website and it appears that it's an improved version of the silver diamine fluoride treatment, which a quick search reveals is FDA approved.


it's different because the risk analysis for individual decisions is completely disparate from the risk analysis of policy decisions.

How is it connected?

Also I'd be interested in you're citation for the fluoride assertion, the last I remember that was a conspiracy theory and the actual published research was mixed and inconclusive?


> it's different because the risk analysis for individual decisions is completely disparate from the risk analysis of policy decisions.

That's true, but when doing the risk analysis for individual decisions, it helps to have actual data to make that analysis. The website says it's safe without justification to say why it's safe, how it's similar to known-safe mechanism, etc.. "Trust me bro it's safe" is not exactly confidence inducing.

There's this recent report. This is for countries where children received fluoride exposure amounts higher than 1.5 mg fluoride/L of drinking water which is higher than what you'd get in the US.

Most of the studies that show lower IQ are in Canada, China, India, Iran, Pakistan, and Mexico where those levels can be reached.
