Why is it when we get a cut in our mouth(the dirtiest place ever) does it not get immediately infected? ELI5

>our mouth(the dirtiest place ever)
The human mouth does harbor lots of bacteria – however, it seems far from the “dirtiest” place on our bodies. Much of the bacteria is beneficial, aids in digestion, and helps keep your teeth clean. Other bacteria can cause gum and tooth diseases, but isn’t actively trying to infect your cuts. Along with a very active immune system in the mouth, cuts here often heal faster than other places on the body.
On the other hand, a cut in you lower intestine (which I would consider much more “dirty”) can quickly become a real issue.
