How does salt water help the pain of a tooth ache?

Answer:
Salt draws out some of the fluids causing the swelling and has a general soothing effect. The saltwater rinse also cleans the areas around the infected tooth. Even unsalted lukewarm water (about body temperature) can flush out an irritating piece of rotting food and provide some relief.
