In America, the sole correction option is to use everyday as an adjective, and every day as a noun. Why does Colgate have the phrase whitens teeth everyday on their toothpaste instead of the imprint whitens teeth every day?

Hi,
Because they don't ask English Forums to check their grammar.
You can't be said to be correct, because you didn't make a statement. You just asked a question.
But their sentence was not correct.
