I checked my Crest when the toothpaste problem first appeared and found the same thing you did. I guess it depends on the law. With canned food, if it is grown/processed out of the country, the label must tell you. So if it doesn’t say, you can assume it’s from the US. I don’t know the laws governing items like toothpaste.
There is no regulation to that effect. The label must contain the manufacturer/food processor's or distributor's name (which is usually a US company), but not the source of the food, which would be (and sometimes is) indicated by the words "Product of (name of country)."
So if it doesnt say, you can assume its from the US.
Actually, you can usually assume just the opposite.
