Baking Soda is used in a variety of household tasks particularly in cooking. It has a slightly alkaline reaction and is able to bring a near neutral balance pH to either acid or alkali solutions. It can deodorise many foul smelling compounds and will reduce mouth odour created by garlic. Used in toothpaste it has a cleaning effect and it leaves the mouth and gums feeling fresh and healthy. Mixed with a little table salt and brushed gently into the gums it will help to heal damaged tissues and dissolved in a little cold water will give a refreshing mouth rinse.
