Given the number and types of bacteria in our mouths, why is it that cuts/ulcers in our mouths don’t get super infected very quickly?

I’ve heard that the human bite is one of the most dangerous because of the types of bacteria in our mouths and teeth. Knowing this, wouldn’t cuts to the inside of our mouths (tongue, cheek, inner lips, etc) also be very dangerous?

Our whole body is infested with bacteria. I think I’m right in saying in terms of numbers they actually outnumber our own cells. Some of these are symbiotic, we rely on them to do what they do, and they rely on us. The large majority of them we have a sort of ‘better the devil you know’ agreement. They don’t do us much (or any harm) and they also outcompete and will fight new bacteria which could be dangerous. So those cuts will be infected, but infected by friendly or at least neutral bacteria.
