Canker sores are painful ulcers that erupt inside the mouth on the gums, cheeks, tongue or lips. Stress, fatigue and food allergies may increase the likelihood of canker sores in some individuals. An injury to the inside of the mouth from a stray toothbrush bristle or a burn from hot liquid or food can also instigate a canker sore. Certain foods often trigger canker sores, such as citrus fruit, vinegar, chocolate and tomatoes. Salt is a natural disinfectant that kills germs and bacteria and promotes fast healing of canker sores.

Purchase Sea Salt

Buy unprocessed sea salt that is sold at health food stores or over the Internet. Refined table salt that is found in grocery stores contains potentially irritating caking agents and other additives, such as the dietary supplement iodine. Salt in its purest form is a more powerful healing aid for your canker sores. Read the salt package label to make certain there are no additives or caking agents before purchasing.

Salt Treatments for Canker Sores

Prepare a salt gargle to promote healing of your canker sores. Fill a glass with warm water. Dissolve 3 tsp. of sea salt and gargle with the mixture three times each day.

Make a cleansing salt and baking soda mouthwash to lessen your canker sores. Add 1 tsp. of salt and 1 tsp. of baking soda to a glass of warm water. Swish the mixture around your mouth and hold for three minutes. Rinse your mouth with this mixture four times each day until your canker sores are eliminated.

You can also add 1/3 tsp. of food-grade hydrogen peroxide and 1 drop of peppermint oil to your gargle and mouthwash for additional disinfectant benefits.

Try a salt toothpaste to relieve canker sores on your gums. Mix 3 tsp. of baking soda with 1/2 tsp. of salt until it forms a paste. Dip your toothbrush into the mixture and brush as usual.

See a physician if your canker sores last for more than two weeks.
