What’s actually different between toothpaste selections

Question

Seems almost all have the same active ingredient even though they promise different things on the label.
Other than a variation of Hydrogen Peroxide for whitening and Fluoride for Enamel – what’s actually different?
Do they have secret “inactive” ingredients that deliver on the promises of the label or is it all a sham?

It’s mostly capitalism. Can’t have just one kind of toothpaste that works – gotta have 12 ‘kinds’ of toothpaste so going to the store makes you die a little.
