7. Baking Soda

baking soda with water

For treating canker sores, baking soda is a very good ingredient as it has anti-inflammatory and antibacterial properties. Plus, it helps restore the pH balance in the mouth.

  • Combine baking soda and a little water to make a paste. Apply it to the affected area.
  • You can also add some baking soda to warm water and use the solution as a mouth rinse several times a day.
  • Another mouth rinse can be made with salt, baking soda, and hydrogen peroxide. Rinse with this solution four or five times a day. Within a day or two, you will feel relief from the pain and other symptoms associated with canker sores.

8. Sage



The calming properties of sage can instantly relieve pain associated with canker sores. Moreover, it has an astringent and drying effect on canker sores.

  • Add about three teaspoons of sage leaves to two cups of boiling water and let it steep for about 15 minutes. Allow the solution to cool and then rinse your mouth with it several times a day.
  • Another option is to apply the powder form of sage leaves directly onto the canker sore. Do this several times a day. You should have complete relief in a few days.

  1. I agree with the ice treatment, I stumbled on that one. Also, Listerine mouthwash helps reduce pain. It won’t speed up the healing, but if you need to eat your meals without experiencing pain when a piece of food or a spice crosses the cancker sore, apply some Listerine to the cancker sore. Heads up, you will experience about 10 seconds of real intense pain that will bring tears to your eyes. If you can grit your teeth through this pain, you will find that Listerine temporarily blocks the nerves and you will have no pain on your cancker sore for about an hour.

  2. Due to a weak immune system, I used to get canker sores all the time. Try using Sensodyne (or the generic version) toothpaste because the ingredient ‘Sodium lauryl sulfate (SLS)’ which is in other toothpastes actually cause canker sores in some people….Sensodyne does not have it. If I do get the occasional sore, I keep diluted hydrogen peroxide around and just poor some on my toothbrush each time I brush until the sore is gone…works every time!

  3. Whenever I get a canker sore, I always make a cup of hot black tea, wring out the teabag then press & hold the hot teabag into the sore, for as long as I can stand it. Then drink the tea. It helps the pain immediately & usually after doing this 2-3 times, the sore is completely gone after a couple days.

  4. Salt works great too..hurts like no tomorrow but it’ll go away…wet finger, stick it in salt and rub as hard as you can in the sore..sounds crazy but it works

    1. Switch to sensodyne toothpaste. I used to get so many all at once, but since I switched to sensodyne, I have only had one in a couple of years.

  6. thanks I just want to try all of these together!! just to make it the pain go away. Dentist told me I must keep my denture in…on top of the sore. and only take it out at night…it is agony …I long for the evening when I can get some relief.
