My family doctor says it's true. Supposedly, dogs have saliva that fights bacteria way better than humans. In fact, he said if you get bitten by a human or a cat, you should definitely start an antiobiotic. If you get bitten by a dog (and it doesn't need stitches), chances are it will heal just fine on its own, with no infection.
I think this statement was based on the fact that a human bite is far more likely to get bacteria infected than a dog bite. Probably because human bites have human germs that affect humans more.
I would say that probably both mouths are equally germy, humans actually expose their mouths to just as much bacteria as your average well-kept dogs do if you think about it. Obviously dogs that dumpster dive are going ot have more exposure to bacteria. Think of all the junk food we eat from all the different sources, especially if we frequently eat out of the house. My dog only gets stuff from stuff in our house or in our yard typically. Also, humans ideally do more to combat oral bacteria by brushing their teeth and flossing.
I dont really know either way. I would say that both are equally nasty. Cat bites have to be some of the nastiest bites. Not because of how dirty thier mouth is but because of the way that thier teeth are shaped. When a cat bites you and his teeth go into the skin they leave saliva down at the bottom of the bite. When the tooth comes out the skin closes and traps the saliva inside making it more likely to get infected. With a dog bite the teeth are bigger causing more damage and they are more likely to bled flushing out some of the germs.
I never got an infection from a dog bite but i had to get almost 3,000 worth of antibiotics when my cat bit me.
I saw some show. May have been myth busters?? Where they tested it by swabbing a dogs mouth and swabbing a persons mouth and it did show that a dogs mouth was cleaner or had less bacteria or something like that.
The saliva is slightly more acidic than humans, so it will kill more germs, and bacteria than the human mouth....not all dogs eat poop...lol, but should we say some things human put there mouths on...not much hygienic (sp)....lol
Interesting topic! I've always wondered what the truth of the matter was. I was always told that dogs had a natural antiseptic in their mouths. After all they use their tongues to clean their wounds in the wild. But they also use their tongues for a lot of other things. Anyway, I guess we really don't know for sure. Call me gross, but I've been letting dogs lick me for years and never had any problems. :)
I feel pretty comfortable with my dogs licking me because I know they are clean but I do have a litle bit of a problem with other people's dogs licking me becuase I do not know how they live, where they been and what their habits are.
Same with people, I would have a hard time letting a stranger kiss me because I do not where he's been.
I probably would have a harder time letting a stranger human kiss me than a stranger dog though.

Since dogs have a much shorter digestive track than people it means they have to break down food, etc much faster. Since saliva is the first stage of digestion dogs have much stronger enzymes in their saliva to get the digestion process started. These enzymes kill off harmful bacteria much more so than human saliva does.
So in reality the dogs mouth is not neccesarily cleaner it's just that the harmful bacteria is killed off faster.
In my work I get lots of cuts , burns etc on my hands and since my kissy dog Sarge has been licking my wounds they seem to heal much faster than they used to.
