They compare themselves to “regular toothpaste”, but are they basically redundant if you use a fluoride toothpaste?
I have a prescription strength toothpaste that has a 100% more flouride that standard toothpaste. Apparently, cavities can “remineralize” given a sufficiently mineral environment in the mouth. But I’m not sure if OTC preparations can contain that much flouride (my prescription toothpaste is clearly labeled as being toxic to children).
I’ve looked at a few labels and they had just normal, non-prescription fluorides as the only active ingredients.
So I think they are scams. The only people who would buy them are people who already take good care of their teeth, the people who buy anti-cavity, anti-tartar toothpaste. Yes, they are legal, because they do include fluoride, but excess fluoride is not of therapeutic value, so they should have a notice they are useless compared to fluoridated toothpaste.
