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?

Bacteria evolve to fit niches and need super specific environments to thrive. Most bacteria which have evolved to be in a human mouth will not do well in the bloodstream or in tissue as the pH is not what it prefers, etc. and it won’t have access to the decaying food particles, etc. it prefers.
