The precise question was: Is a dog's mouth cleaner than a human's? The answer to that is no, too, and basically for the reasons you've already cited. As we all know, dogs aren't particularly fussy about where they put their tongues or what goes into their mouths.
Dogs have more acidic skin than humans. However, according to groomer Barbara Bird, pet shampoos had a pH range of 2.2 to 7.5, while many human shampoos had a pH range between 5.0 and 6.5. Bird says the difference in the pH range among the pet shampoos is greater than that between human and pet shampoos.
