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

The increased likelihood of physical trauma to mouth tissues means more opportunity for infection in that population specifically because they lack the proper immune response that protects you from such opportunistic infections.
