Canker sores, though a relatively minor complaint, still manage to be one of the most vexing and uncomfortable injuries. While more severe canker sores may require the assistance of a dentist, most can be successfully treated at home. If you would like to learn more about how to reduce the discomfort of canker sores, read on. This article will provide three DIY remedies guaranteed to bring relief.

Baking Soda

Baking soda is probably the first thing you should reach for when you feel a canker sore coming on. There are two ways to use this handy powder. First, add just enough water to make a thick paste and use a cotton swab to apply it to your sore. For best results, try not to disturb it until it has naturally dissolved. In addition to easing the pain, when repeated, this remedy will also speed healing.

Another way to implement baking soda is by making a mouth rinse. Dissolve around 1/2 teaspoon of baking soda in half a cup of water. Gargle this mixture for as long as you're comfortable and then spit it out. Using this tactic several times a day can help to reduce the degree of inflammation. Just try not to swallow the mixture--while baking soda isn't poisonous, it can cause gas and discomfort.

Hydrogen Peroxide

Like baking soda, hydrogen peroxide has a seemingly limitless number of home remedy applications. To treat canker sores, made a solution comprised of equal parts hydrogen peroxide and water. Then either use this as a mouth rinse, or apply directly using a cotton swab. As well as relieving the inflammation, hydrogen peroxide's antiseptic properties will help to kill the bacteria responsible for causing canker sores.

You may also find that applying small doses of undiluted hydrogen peroxide also offers relief. However, it is recommended you do this no more than once a day--and generally for no more than two or three days at a time. As with baking soda, be sure not to swallow any hydrogen peroxide, as even small doses can lead to an upset stomach.

Milk of Magnesia

Don't let its name fool you--milk of magnesia is not a dairy product. Rather, it is a white liquid made out of magnesium hydroxide. Though most commonly taken to combat excess stomach acid and other gastrointestinal disorders, milk of magnesia can also offer significant canker sore relief when small amounts are applied directly using a cotton swab. This remedy is often recommended as a follow-up to treatment with hydrogen peroxide.
