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

Question

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 ).
