Salt has pronounced antibacterial agents, so it can be a temporary replacement for toothpaste. Mix some salt and warm water, dip a finger, a paper towel or a napkin in this mixture and brush your teeth. However, if you have metal fillings - this method will not work for you, since salt causes corrosion.

Metal fillings are not metal. They are a silver amalgam. If they were metal, they would rust. As much salt as they put in our food today if fillings were metal they would last about one week. :yes:
