    1. No, you should not use baking powder instead of baking soda in the above mentioned methods. Baking powder and baking soda are different in nature.

    1. It is difficult to tell the exact time as everyone’s condition is different. So, try the remedy regularly until you see the results. However, you may observe improvement in few days.

  1. So I had a canker sore of the past 4 days and it hurts like hell. I tried leaving it alone so that it can heal by itself but i can’t handle the pain and the discomfort especially when I’m trying to eat.. I tried washing out my mouth with listerine, that didn’t seem to help so i tried hydrogen peroxide. Sadly that really didn’t seem to do much either. So then i decided to try baking soda. So i placed the baking soda directly on the sore and it burned like hell. Seriously my heart started racing, my head started to hurt and I felt so dizzy because the pain was excruciating. Its like throwing salt in a wound. Man, I felt this pain in my toes. Moreover the sore started bleeding. But what i have noticed is that the white cast over of the sore has somewhat disappeared. This is literally happened within 5 minutes of applying the baking soda. My question is it natural for the canker sore to bleed after you apply baking soda to it? So i be alarmed?

    1. It might have caused to excess amounts of baking soda application. As it is bleeding we recommend avoiding further application of baking soda and consult a doctor.

    1. Yes, baking soda solution can be used to dissolve existing kidney stones. Being alkaline in nature, it reduces the high acidic environment in the kidneys. So, it is also helpful in preventing the formation of kidney stones.

  2. THANK YOU!!! I get so many canker Sores and this works so well. I just used it and it stung ALOT at first but I waited 5:00, washed it off and it instantly feels better! (I used the paste option)

  3. I have to say how grateful I am for tip #1 – making a paste with some Baking Soda and water. I suffered terribly for a good 5 days with an ulcer underneath my tongue. It was sooo uncomfortable, making it difficult and extremely painful to talk, eat, etc. I tried various recommended home remedies including tea tree oil, honey, but nothing seemed to work in terms of starting the healing process. As a last resort, I tried the baking soda paste. Heads up – I nearly passed out from the pain/sting when I applied it! Tears sprung to my eyes and the thought “just shoot me instead” flashed across my mind. BUT…… maybe 30 – 45 seconds in, the initial discomfort eased a bit – enough for me to hold the paste in my mouth for a few minutes as recommended, and even try a second application. Can I say that by the time I rinsed out my mouth after keeping the paste on for as many minutes as I could bear, I felt an IMMEDIATE difference. I literally could not believe the difference in just a few minutes. I went to bed after that and woke up the next morning feeling much much better. The discomfort of the ulcer was not completely gone, but I could eat comfortably, and I was no longer speaking like a drunken sailor. I did the application again for good measure – and yes ,again the staggering burning/stinging, but I gritted my teeth – literally and figuratively, bore it for 3 or 4 minutes (by which time the paste starts to dissolve anyway), and I’ve been home free ever since! Within hours I was much much better, and by the following day, I pretty much forgot that I had had an ulcer that tormented me for days before discovering this treatment. I would not recommend putting the baking soda directly on the sore without diluting it as based on my experience with the paste, I personally feel it would be way too strong, but a definite thumbs up for the paste.

  4. The advice given here is great, thank you. I am a fan of baking soda for many other remedies, just never tried it for my son who seems to suffer with frequent canker sores.
    The comments are extremely helpful. Thank you all for sharing.

  5. Ok so I just tried the paste and omg I wanted to cry it’s still stinging right now but hopefully it starts feeling a little better soon ?

  6. I tried the baking soda *paste* and after a few minutes i feel like i can smile and eat again in a comfortable way.
    When i tried it my first impression is
    *Im crying and i realize that this is the way that can help me*
    Thanks

  7. I applied the baking soda directly on the canker sore and it caused it to swell. Is that normal? Why would it cause it to swell?

  8. I tried the past option and it worked absolutely Amazing! I cured my mouth sore in just a couple days.I highly recommend these remedies.
