Natural Remedies for Canker Sores

My poor hubby has suffered from horrible canker sores. It makes me cringe just to think about them. Well, it did- until I learned how to help him with natural remedies!

When a person gets canker sores, it means they are really run down. They need some rest and nourishment. For ideas, check out this post. It’s specifically about colds, but the same things apply to this.

Bentonite Clay

This is the ultimate way to stop a canker sore before it really gets going! At the first sign of the canker sore starting, use a cotton swab to gently dab on some dry bentonite clay. Do it as often as you want, but always at night and at least once more during the day.

We have discovered that if my hubby applies it the first night he feels a canker sore starting and again the next morning, it will heal within a day or two. If he doesn’t, it lasts for one to two weeks and gets really bad. The herbal remedies help it to heal faster and to sooth his mouth, but the bentonite clay keeps it from being an issue in the first place!

We have noticed that if he waits until the day after the canker sore starts, the bentonite clay doesn’t help even half as much, so get it on there ASAP. 🙂

  1. I cure canker sores instantly by pressing a salt pack on top for several minutes. Wet my finger then dip it in salt and apply this directly onto the sore about four or five times. I do it over the sink as the saltiness causes salivating. It’s a bit painful at first, but I have yet to keep a canker sore for a full 24 hours after treating it this way.

    My dentist told me that frequent canker sores could be a sign of celiac disease or gluten intolerance. I didn’t know this till recently, I had sores frequently but I have been gf for 5 years and haven’t had one since.

  3. Ooo, love this use for bentonite clay! I’m going to have to remember this the next time my husband or myself gets a canker sore. Thankfully it’s been years since I’ve had one, they are annoying.

    • Hi Annie, Although it does work for some people, hydrogen peroxide damages living cells and can cause free radicals. With all the other toxins we encounter that cause free radicals, it’s probably a good idea to use something that won’t contribute to that. 🙂

    Sodium laurel sulfate can cause canker sores for many individuals. Check your toothpaste and mouth rinse, if they contain SLS find a different product like Biotene. Also avoiding acidic foods can help as well.

    • Very true, Dawn! We haven’t used toothpaste with sodium laurel sulfate in years! We make our own toothpaste or tooth powder or we buy some all-natural, fluoride-free, non-toxic ones. 🙂 Thanks for pointing that out!

    In school (for holistic nutrition) we just discussed canker sores the other day..our teacher said it’s due to food sensitivities/allergies. Get tested and maybe do an elimination diet. One responder said she took out gluten…that would definitely point to an allergy/sensitivity. =)

    Thanks for some of the tips i have used bentonite clay for a while now my poor husband has literally used every thing he gets them very often it seams to be at least 1ce a month or so they some times get the size of dimes and a few times quarter size and the only thing that gives him some relief is equal parts bentonite clay sea salt and clove powder.

    • Poor guy! I have heard of people who get them that often and that severely finding out that it’s because they are eating something that they are sensitive or allergic to. You might want to try an elimination diet to see if he’s reacting to gluten or dairy or something. I would definitely suggest avoiding toothpaste with sodium laurel sulfate. That triggered them all the time in my hubby.

    I have always had great luck with lump alum. Take a piece and put it right on top of the canker sore, hold it there for a while and it will be gone the next day. The alum dries up the sore. It stings for a minute and tastes funny, but it works every time.

    I put baking soda on the ones I get on my tongue. Just put it on dry, then lean over the sink with your mouth open. Stick your tongue out and wait for about two minutes. You will drool, but don’t close your mouth or swallow. Just drool and wait! Mine are always gone within a few hours to overnight.

    • Yes, they just have that warning on there to avoid the red tape with the government regulations. There are other brands that have gone ahead with all the red tape and have been approved for internal use, so that is absolutely and option, if you’re more comfortable. 🙂 In this case, though, we don’t actually ingest large amounts of it, so it doesn’t bother us. 😉

    I had read that when you get canker sores you are missing Vit B. So we always eat rice when we have canker sores. The next morning they are gone.

    • That’s wonderful, Elizabeth! I do know that food sensitivities and foaming tooth paste can trigger them, too, so some people might want to keep an eye on that, as well. 🙂

    Im going to have to try some of these until I can get my daughter into the dr. Over the last 2 months she has started getting canker sores. Currently she has 4. Poor girl! Anyone else experience this?

  11. Gargling with just a dash of cayenne peppers (CP) and/or applying a little CP literally cures cankur sores within a day and often require no more than 1-2 treatments. And no, it does not stink but only feels a little hot if applied on a sore unless its on the tongue where taste buds are. Capsaicin in CP is also an excellent analgesic & takes the pain away within a minute or two 🙂 CP gargles are excellent for sore throats too.

    Many of cancer patients who experience lots of cankur sores during chemotherapy tell that they find gargling with baking soda very helpful.

    I’m confused, canker sores are not caused by a virus. They are apthous ulcers in the mouth with an unknown autoimmune etiology. Cold sores found outside the mouth are from a virus. Which is this article talking about?

    • You’re absolutely right! I was going on what my hubby was told by his dentist when he went in to try to get some help. Apparently we were misinformed. I’ll update the post with immune-boosting herbs as soon as possible. Thanks for catching that, Becky! 🙂
