Not sure what you typed into Google, but I did and found several sites.

Answer 2

ALL I KNOW IS THIS: A DOG'S MOUTH IS WAY MORE CLEANER THAN A HUMANS. THIS IS HARD TO BELIEVE BECAUSE DOGS LICK THEIR PRIVATE AREAS AND DRINK OUT OF THE TOILET! TRUST ME ON THIS ONE, U WOULD PREFER TO BE BIT BY A HUMAN THAN A DOG. DOGS CARRY RABIES IF THEY'RE NOT VACCINATED. A CAT'S MOUTH REALLY SMELLS BAD, BUT I BELIEVE THAT THEY MUCH MORE CLEANER THAN A DOG AND A HUMAN. OK, CATS LICK THEIR PRIVATE PARTS AS WELL, BUT THEY DON'T STINK. A HUMAN'S MOUTH IS DEPENDED ON WHAT THE HUMAN EATS. U WOULDN'T WANT TO BE NEAR A HUMAN WHO SMOKES OR DRINKS LIQUOR!

Maybe there's something you can use on this site; I did a search for: mouth cleanliness and this is what turned up.

Hope it's useful.
