Baking Soda Solution
Using baking soda for canker sores work almost in the same way that salt solution works. When used for canker sores, it helps to reduce the inflammation. To prepare baking soda solution for canker sores, add a teaspoon of baking soda to half a cup of water, then rinse your mouth with a mouthful of the solution gradually until you exhaust the solution. Do this a few times every day until the sores heal.[4]
