Help understanding the difference between two toothpastes fluoride content

Question

I’m comparing two different toothpaste that I’m interested in switching to. The first toothpaste outlines the fluoride content as follows- sodium monofluorophosphate 0.76% (0.15% w/v fluoride ion)

The second toothpaste outlines the fluoride content as follows- Sodium fluoride (0,243 % p/p)

Is one better than the other? If so, why is that?

Answer 1

Fluoride is the active ingredient, but fluoride is normally with something else bound onto it as a chemical compound. Toothpaste is generally used in larger quantities than is needed for the job, so differing levels of fluoride or what it is bound to are largely the same.
