Eli5: Why is sodium fluoride added to the toothpaste when it’s calcium fluoride that is actually helping the teeth?

499 views

I’ve read multiple journals on this subject, and I can’t seem to find a logical explanation as to why they substitute calcium fluoride for sodium fluoride. Matter of fact, all the research i’ve read highlights dangers with the use of the sodium fluoride version including reductions in intelligence (in mice ).

Fluoride is the chemical we want for teeth. It’s an ion, which is why the chemical additive is sodium/calcium fluoride. It basically helps to strengthen tooth enamel and has huge public health benefits as a result.

As far as the dangers of sodium fluoride… I would recommend that you be cautious about anything you read regarding it. There’s a lot of people that are anti-fluoridation of the public water supply and sodium fluoride is a common compound used for it. They tend to use very questionable “scientific” methods to claim that it’s unsafe.
