I’m very much anti fluoride in drinking water. And did not buy fluoride tooth paste for my kids until they learned to spit.

But 1) kids brush teeth to form a healthy habit, and protect their gums. Kids who do not brush teeth often develop gum disease which can cause tooth loss in the future as adults.

2) residual fluoride isn’t anything to worry about. Just spit the toothpaste out. If you’re super worried about fluoride then look for calcium fluoride toothpaste which is not poisonous.

3) sloshing vodka or whiskey around doesn’t remove plague from your teeth and you will suffer tooth decay regardless.

Whats the point of calcium fluoride in your toothpaste, the water solubility is very low I would suspect it to do almost nothing, could be wrong, never heard of this. Generally soluble salts like sodium or tin fluoride are used.

Sodium fluoride is a by product of aluminium production and is poisonous in high dosage. That’s why people are so anti fluoride.

Calcium fluoride is naturally occurring and was what was discovered to be so good. Well the water it was first discovered was contaminated with sodium fluoride from aluminium but the water that promoted the research was calcium fluoride.

But while sodium fluoride is poisonous in high levels. You could drink super high levels of calcium fluoride and be totally fine.

So if you’re super worried about sodium fluoride (which you shouldn’t be in tooth paste since you should spit it out and anything you swallowed is harmless as the dosage is so low) then the alternative is to source tooth paste with calcium fluoride. Which is harder to get but it does exist.

The fact that its produced from aluminum refining is irrelevant. Also everything is poisonous in high enough doses.

I understand that calcium fluoride isn't going to harm you because its not soluble, its just like eating some inert rocks but its basically pointless to add to toothpaste.

I'm not worried about fluoride, its very helpful for dental health, I did a bunch of my PhD on this.
