Salt draws out some of the fluids causing the swelling and have a general soothing effect. The saltwater rinse also cleans the areas around the infected tooth. Even unsalted lukewarm river (about body temperature) can flush out an irritating piece of rotting food and provide some relief.
It doesn't comfort the pain, but it will relieve it heal faster.
If the tooth is abcessed, the saline helps to draw.
I alwaus use clove grease on tooth aches. Never hear of using salt marine on tooth aches.
