This is all so fucking stupid!

Flouride provides unarguable protection from cavities. To do so it needs to come into contact with teeth.

Flouride also (very likely) has brain health implications. So you should not swallow it.

Obvious solution! : what every dentist already does, swish some flouride or hold it against your teeth, then spit it all out.

Our politicians who want to put it in, and keep it in the water can go right to hell for brain poisoning our youth.

Jokes on you, I’d pay $1 for the lot.

The problem is far greater than that.
