5. Rinse with baking soda and aloe vera juice
Both baking soda and aloe vera gel can be effective treatments for canker sores on their own. Therefore, it stands to reason that combining the two can make for an even more powerful home remedy. To make this rinse, you will substitute the gel of an aloe vera plant with juice from the plant.
Combine 2 tablespoons of the aloe vera juice with 1 teaspoon of baking soda. Add ½ cup of warm water to the mixture and stir until well blended. Once the aloe vera juice and the baking soda have fully dissolved in the water, take a sip of it and swish it around your mouth, paying close attention to the area where the canker sore is located.
Spit out the mixture, take another sip, and repeat the same process until you have rinsed with all of the mouthwash.
