12 Quick & Easy Remedies for Canker Sores

Canker sores are no fun. Even though canker sores are often hidden behind the gums, the pain and discomfort that canker sores cause make you unable to smile, talk, eat and drink.

Canker sores are no laughing matter. Even though they aren’t permanent and don’t signify a serious underlying disease, they wreak havoc on your social and physical comfort. Using one or more of these remedies for canker sores may help your sores heal faster or prevent outbreaks from happening in the first place.

Salt Water Rinse

Salt water is a natural canker sore remedy that is readily available to everyone and easy to use. This remedy for canker sores is a tried and true treatment that actually works! By using this method, you effectively speed up the healing process.

Why a Salt Water Rinse is Great for Canker Sores

Salt water is a natural drying agent (aka, it helps dry other substances out).

How does that work?

Well, applying salt results in the process of osmosis, whereby cells transfer moisture from one cell to another. When you rinse your mouth with a salt water solution, the salt dries the sore (as the water from the sore and surrounding area transfer to the salt) and heals it a lot faster.

What Kinds of Salt are Good for Canker Sores?

The beauty of this remedy is that you can use any kind of salt that you have available, including table salt, Himalayan salt, and Kosher salt.

How to Use a Salt Water Rinse on Canker Sores

  1. Get a clean glass.

3. Soft-Bristled Toothbrush

Canker sores make your gums extremely tender. Using a soft bristle toothbrush will keep you from accidentally the grating against the canker sore, which will make it take longer to heal.

Why a Soft-Bristled Toothbrush is Preferable for Canker Sores

One of the worst things that you can ever do is to avoid brushing your teeth and gums altogether. However, if you use a medium or hard bristle toothbrush, you definitely run the risk of irritating your canker sores. A soft bristle toothbrush is preferable for canker sores because it allows you to brush your teeth and gums without irritating the canker sore. Then, if you do accidentally brush over the canker sore, you will do little or no damage.

How to Use a Soft-Bristled Toothbrush

  1. Locate a soft bristle toothbrush at stores that carry ordinary toothbrushes.
  2. Brush carefully around the canker sore using the soft-bristled toothbrush.
  3. Apply a little more pressure in areas where you don’t have a canker sore because the soft bristle toothbrush may not get the rest of your teeth clean enough.
