I used many different things for the big sore on my tongue. Nothing would work, until I started to use the clove powder.. It started to work immediately.

I've learned that canker sore can be caused by bacteria or many other causes. In my case, it was bacterial, from a tooth infection. In 2 days it shrunk 80%..another 2 days later it was gone.

Avoid SLS Toothpaste

Avoid Sodium Laurel Sulphate in foaming toothpaste, cleansers etc. I am a 58 year old female and have suffered on and off with canker sores (aka mouth ulcers) since my teens, although sometimes going for long periods with none. However I have recently had two cankers on the gums of my lower front teeth which just will not go away. Normally a canker sore would last about a week, but I have had these for approximately six weeks. I have been doing extensive research and believe I have discovered the cause : sodium laurel sulphate (SLS). I was using hydrogen peroxide on the sores for healing and also using a purchased baking soda toothpaste,, but did not realise the toothpaste contained SLS. I have also been using a foaming cleanser with SLS on my face which may or may not contribute to the issue. I believe I have developed a sensitivity to SLS and will now need to avoid it. Just thought that might help someone.

Lavender essential oil will heal both canker and cold sores. I put some on my finger and apply 3 or 4 times a day. Works in no time.

I had nasty canker sore on the roof of mouth. I tried everything on here for relief. It all helped some. Then I remembered that I have some cbd oil balm. I loaded up a Q-Tip with it and placed it everywhere I felt pain or tenderness. Went to sleep. Woke up pain free. Like it went away over night. That stuff is the best for any type of skin lesion.

Canker Sore vs. Cold Sores

Canker sores are NOT caused by the Herpes virus.

Mayo Clinic: "Unlike cold sores, canker sores are not associated with herpes virus infections."

Canker sores are in the mouth and cold sores are on the lips. Both are Herpes Simplex viruses {not genital herpes} and every one has one or the other in their system. Usually domant until something triggers it. [Am a nurse}.

Peppermint Oil

Peppermint oil seems to have shrunk the canker sore I had. I was putting a drop of the oil in my mouth once a day. That was three days ago, the sore is gone. It had been there about three days before I used the oil.

I mixed several drops with tea tree oil in a capsule and inserted it to see if it would get rid of what appears to be hpv on my cervix. That was 12 hours ago and my period has just started a week early.

When I feel a canker or cold sore starting, I liberally apply Lavender essential oil 3 or 4 times a day and it's gone in no time. Stops it in its tracks.

Thanks, I will try this. Do you put it directly on the cancer sore or do you just brush your teeth with it? I already use a sensitive teeth type tooth paste and I get them but not often.

Dry Sage leaves are also great for canker sores. It's a cheapest way to get rid of cancer sore and related bb. Just chew a pinch of dry Sage leaves all day long. Place this mass on canker sore for an hour. Can swallow it easily without any side effect. Just avoid scratches - chew only leaves. You'll get rid of canker sore just in a day/or 2-3 days in severe and multiple cases. Also wash your brushes with soap everyday especially they stay as a bouquet in glass in your families.

I get mouth ulcers but years ago someone told me to try colostrum. Now whenever I feel one coming on, I take a capsule and it usually disappears.

Baking Soda

Since childhood I have suffered from mouth ulcers. Usually rinsing with H2O2 works by rinsing several times a day and before going to bed. The next day the ulcer is nearly gone or completely gone. But not this time! Sometimes when my seasonal allergies kick in I get a patch of ulcers. This spring has been the worst ever. Ulcers popped up on the left side of my mouth on the cheeks, gums and under the tongue. So painful and the H2O2 was not working at all. So I came back to this site where I have learned so much over the years -- thanks to all the contributors! Decided to attack the ulcers by taking Echinacea, Lysine 2000-3000 mgs per day on an empty stomach and applying baking soda to all the areas. The first day I got immediate relief from the pain and inflammation on the left side. Kept applying baking soda all day. Slept better that night. Next day the left side was on the way to being healed BUT new ulcers emerged under the tongue and along the gums on the bottom row of teeth as if they were marching to the uninfected right side of my mouth. Yikes! Continued the above protocol plus brushed my teeth with baking soda and continued to place a half teaspoon under the tongue and between my bottom lip and lower gum. Good news. The new ulcers begin to recede with each application of baking soda. Thanks Earth Clinic -- God bless you all!

Baking Soda

Thanks for those sharing about the baking soda remedy, I have been bothered with several canker sore in my mouth and cheeks in the last few days and they were very painful and have lost my appetite in eating. After trying a few solutions, they didn't really work for me and out of desperation, I applied some baking soda paste over the sores last night, while they haven't gone away, it did reduce the level of pain and hopefully they wil go away soon. Big thanks for sharing!

The best for canker sores is Lugol's Iodine 5%. Take 5 drops in the morning on empty stomach for about 2-3 weeks, they will never come back.

My 6 year old son got a canker sore a few days ago. The pain was getting progressively worse. I tried rubbing some coconut oil on the sore at bedtime... it was gone by morning. Would use it again as he gets canker sores frequently.

Raw natural honey worked very fast for me. I had a very painful canker sore for over a week. I tried salt, baking soda and collodial silver with no improvements. I read on here to try raw honey and I noticed relief the very first day. Within two days of dabbing raw honey on it several times per day the sore was almost gone. It was a huge relief and a yummy remedy!

I always take lysine for canker sores. Recommended by my Dr 40 years ago. Also use peroxide. Usually goes away within 5-7 days.
