i’ve found information as to why saltwater rinses help heal oral wounds, and i’ve also found information as to why salt can be bad for other wounds, but i can’t figure out what’s different about oral wounds.
just had my wisdom teeth taken out and i’ve been wondering this

It’s less about the location of the wound than the amount of salt. You can, in fact, “irrigate” or wash out other wounds with salt water if it’s clean.
Pure salt pulls water out of your cells, shrinking and possibly killing them. But depending on the concentration, salt water can do this more gently (good for removing fluid build-up from a wound) or not at all, if the salt concentration in the water matches the salt concentration in the tissue.
