Baking soda
Baking soda is present in the kitchen of virtually every home. They are usually placed in refrigerators to reduce odors, but they have antibacterial properties. People with tooth infection can wash their mouth with a solution of baking soda and warm water, it helps to alleviate the pains and reduce the level of plaque. Pains at the side of the tooth or gums can be reduced by applying a paste of baking soda and water directly to the tooth or gum rather than washing. However, if the infection is in other places of the tooth the best method is rinsing.
