8 Canker Sore Cures and 1 Prevention Tip

Hydrogen Peroxide

Hydrogen peroxide may help reduce and relieve canker sores. Simply mix one part peroxide with one part water, then dab on any affected areas several times a day or swish around in your mouth for as long as possible.


The same chamomile tea that soothes a sour stomach can also calm canker sores. Allow the tea to cool, and then swish it around your mouth for a minute. Chamomile contains chamazulene, a natural anti-inflammatory agent, which will help accelerate the healing process.


Hold a damp tea bag over the area. Tea bags are filled with healthful tannins. Cool the tea bag for even more relief.


Dabbing unpasteurized honey on canker or cold sores four times a day will help them disappear fast, thanks to the enzymes it contains.

Suck on Slippery Elm

Native Americans have been using slippery elm for centuries to treat mouth, throat, stomach, and digestive ailments. Today you can buy slippery elm lozenges, available at health-food stores, which will provide lasting relief for canker sore pain. They’re also effective for coughs and sore throats too!

Baking Soda

A natural antacid, baking soda is a great canker sore remedy. Dissolve ½ teaspoon baking soda in a half cup of warm water, then swish it around your mouth. Baking soda is alkaline, so it will neutralize the acids in your mouth and relieve pain. A simple salt water rinse will help heal the sore as well.


If you need on-the-go relief, a chewable antacid tablet is an ideal alternative to a baking soda or salt rinse. Just as antacids neutralize the acids in your stomach, so too will they temporarily neutralize the pain of a canker sore.

Vitamin E

To help heal a canker sore more quickly, dab a little vitamin E oil on the spot several times a day. The easiest way to do this is to break open a vitamin E capsule and apply it. The oil will coat the painful area and protect it.

Prevention, Prevention, Prevention

Your mouth is filled with bacteria, both good and bad. To make sure the good bacteria are on the winning team, eat a half-cup of plain yogurt every day. It can help prevent painful canker sores from ever forming in the first place.
