13 Home Remedies for Canker Sores
These natural home remedies will cure your canker sore and help it heal quickly.
Milk of magnesia
Sip a small amount and use it as a mouth rinse, making sure to rinse the canker sore itself. This treatment takes advantage of milk of magnesia’s antacid properties, neutralizing the acids in the mouth that cause your canker sore to sting. You can also dab milk of magnesia directly on the canker sore with a cotton swab 3 to 4 times a day; one variation of this cure mixes a teaspoon of milk of magnesia with a teaspoon of Benadryl liquid allergy medicine.
Tea is an alkaline, so it will neutralize acids that irritate the sore; tea also contains compounds that may help relieve pain. Apply a damp tea bag to the canker sore for five minutes to feel some relief.

Sage kills bacteria and viruses, and contains compounds that reduce inflammation. Steep 2 teaspoons of dried sage in a cup of boiling water, covered. Let cool and use as a mouth rinse 2 or 3 times a day; for an effective cure, make sure to swish the tea in the area of your mouth with the canker sore.
Hydrogen peroxide is a strong disinfectant and will protect your canker sore from becoming infected. Use hydrogen peroxide the same way you would use mouthwash, making sure not to swallow any of the liquid. Or try making a disinfecting mouth-rinse treatment by combining 1/4 cup hydrogen peroxide, 1/4 cup water, 1 teaspoon baking soda, and 1 teaspoon salt. The baking soda is an alkaline, which provides extra relief by neutralizing acids. Hydrogen peroxide and salt will both help the sore to heal.
Munch a chewable Pepto-Bismol, Tums, or Rolaids tablet or put it on the sore and allow it to dissolve. The pain you feel from a canker sore is caused by acids and digestive enzymes eating into the tissue in the sore, and the tablets will neutralize the acids to help cure the sore. Check the label for dosage directions.
Rinse your mouth with salt water for 30 seconds to help your canker sore heal. Higher concentrations of sodium chloride draw water from surrounding tissues by osmosis, which helps heal abscesses and open wounds such as canker sores.
Many experts think lysine, an amino acid, may be needed to fix a deficiency associated with canker sores. Check with your doctor if you should take 500 milligrams of L-lysine 3 times a day until your sore is healed. Vitamin C also might help, as it works to heal your mouth’s mucous membranes. While citrus fruits are loaded with vitamin C, they may actually cause canker sores in some people; try 1,000 milligrams vitamin C supplements 3 times a day. Zinc is another home remedy worth trying for this condition. As soon as you detect a sore developing, take 30 milligrams of zinc lozenges each day until it’s gone.
