The Aspirin Cure for Canker Sores

Jul 26, 2016


Aspirin is a super cheap and very effective home remedy for canker sores. This remedy is less painful than many natural treatments for canker sores; in fact, the aspirin, being a pain reliever, often takes the pain away from the canker sore as well as bringing healing to the sore.

How to Use Aspirin for Canker Sores

Take one aspirin and crush it between two spoons. Sprinkle the powder onto the canker sore and let it slowly dissolve. Some of our readers apply the aspirin whole to the canker sore; this is especially helpful when used overnight. Adult or baby aspirin can be used. Coated aspirin should not be used.

Cautions for the Aspirin Treatment for Canker Sores

Do not use more aspirin for canker sores in a day than is recommended for oral use. The aspirin will be absorbed into the body and also swallowed. If you have a bleeding disorder, or low platelets, bear in mind that aspirin is used as a blood thinner and has anti-platelet properties. If you take prescription blood thinners, be sure that aspirin is compatible with your medication.

The aspirin cure for canker sores should not be used by anyone under the age of 18 if he also has chicken pox or the flu because of the risk of Reye's syndrome.

When I am under stress I tend to get canker sores. I have tried many remedies over the years. It is wonderful that there are so many natural remedies for these things!

Recently when I had a canker sore, I decided to try aspirin just to see how well the remedy worked. I love that aspirin can be bought nearly anywhere and it is very inexpensive.

I took an aspirin and placed it against the sore and let it slowly dissolve. I did this a few times during the day and also overnight. Not only did the aspirin cure the canker sore, it brought great relief to the pain.

You can get a bottle of 100 aspirin for a dollar. So this remedy costs a penny per application. What a deal! :)

Well, I tried the aspirin remedy, for a canker sore between my upper lip and gums... Cannot smile can barely talk. ALMOST cant even eat... I took off the rubberlike coating of the aspirin and shook out the powder then set it directly on the canker sore. VERY painful for a moment.... But its a good way to stop the pain of the ulcer :)

This does help immensely. I recently developed a mouth full of sores. Talk about pain. I'm still not sure what caused this because I never get them. I don't think it actually "cures" them, but it makes them feel better right away. I just let one dissolve in my mouth as close to the sore as possbile. No need to make a paste as aspirin dissolves very easily.

I had a canker sore on the side of my tongue, which was painful. I tried the ACV as it is quite a cure-all, but it only stung and the sore was still very tender an hour later. I decided to try the asprin remedy - I bit it in half and put the powder on the sore. Within 10 minutes the pain was gone. I am now eating and drinking and can not feel it anymore at all. WOW! I recommend the asprin remedy to cure canker sores!

Thanks so much for this site! I wish I had it years ago and would have endured a lot less suffering!

I tried the aspirin on the canker and it worked beautifully! I had one between my gum and my lip. I stuck an aspirin on it as per the various ppl's posts and let it sit for about 30 mins. The surrounding skin felt a little funny for awhile but the canker itself seemed to be gone completely. It was definately worth it. It's like it just shriveled up and closed up. Boy what a miracle! This site is a Godsend- thank you everybody!

I was at work and within one hour I went from fine to unable to speak without a lisp, unable to swallow, unable to eat, and in severe pain from my tongue down through my throat. The culprit was what I call a canker sore on the side of my tongue. I looked up remedies on this site and had planned to use the apple cider vinegar, but could not find any. However, I did have some baby aspirin. I used one 81mg baby aspirin and held it on the sore for as long as it lasted. I felt much, much better, but still had some irritation. I used another baby aspirin on it before I went to bed and by morning, NO PAIN at all!

I have used apple cider vinegar to sooth a mouth sore on my tongue...but the most helpful remedy was dissolving an asprin in water and letting it soak. If you can stand the bitterness, the relief is amazing.

Cure for canker sore. Finally after 25 years of trying different products/natural remedies/prescription drugs, I have found the only things that has worked for me to take the pain away from canker sore. Last week, I had a very large sore on my inner lip which was causing me extreme pain to the point were I couldn't eat or talk. I decided to crush a baby Aspirin and put it on my sore for 10 minutes before eating dinner and 10 more minutes at bed time. Well, to my complete disbelief, the pain was gone and never came back. Right afer the application I looked at my sore and it was covered with a white film of skin like materiel. It was almost like if the Aspirin had cauterized my canker sore and burnt the nerves in and around it. The sore took a few more days to heal completely but the pain never came back. That is by far the most wonderful product that I have ever used for canker sore. I can't believe I have suffered for so many years before finding that treatment. Word of advice though. The acid in the Asprin could probably burn your gum, skin inside the mouth if you kept it in your mouth overnight. Don't use it longer than 10-15 minutes but please try it. It works big time.

I tend to get ulcers on the roof of my mouth. Salt water helped somewhat, but I happened to read Dr. "You, the owner's manual." It was advised to take 81 mg. baby aspirin daily. I wish I'd have done it sooner. Haven't had any ulcers since.

Aspirin is best remedy for soothing canker sores. I have been suffering from a canker sore for 2 days and just got so overwhelmed with the pain that I couldn't take it anymore. I used OTC medicines, but none really helped. I found this site and tried Alum first. It hurt a lot, but helped for about 20 minutes. The pain came back, but worse. After suffering for awhile I tried Apple Cider Vinegar. That hurt a lot too, and seemed to be helping, but again the pain returned. Finally I tried making the aspirin paste, and now my sore only hurts a little bit. The aspirin is definitely the best soothing agent for me. I hope this helps convince others to try it as well.

I crushed one aspirin tablet in a shot glass, added a few drops of water and let it sit for a few minutes. I then spread the paste on the sore, which is on the roof of my mouth. I tried to keep the area dry as possible, and so bit down on a wash cloth to soak up my saliva. After 10 minutes I noticed a definite change in the amount of pain I had, and 10 more minutes gave me complete relief.

This little remedy was a miracle for me. I had been suffering from a canker sore for days and nothing worked. Not even medication. I came across this website and I tried the Aspirin paste. I cut an aspirin in half, crushed the aspirin got a q-tip and rubbed it on and left it for about 30 min. After 30 min it was instant pain relief. The next morning I felt much better and the canker sore was smaller. I truly recommend this remedy it worked Miracles for me and I have tried many different remedies and this worked the best.

Nobody I have ever met gets canker sores as bad as me. I got one in the worst spot possible, right on the side of my tounge. With every mouth movement I have pain. I broke an aspirin in half and held it on there for about 5 minutes. Pain was gone immediately. It's quite amazing. Thank you.

I have canker sore on cheek or tougue quite often, about once every 2 months. I try to avoid bread because I think this closest I can think of the relation. I tried 3 remedies that I saw here, ACV, Baking Soda and Aspirin. Aspirin is the super fast one to stop the pain and feel good right after the 1st application. What I do is split the aspirin in half and one half right at the canker. It will dissolve over time and pain is gone. I used this remedy 2 times and they both worked so I need top share with everybody. ACV & Banking Sode don't work for me.

This really did work and on the first try - I googled this today at work and as soon as I arrived home I went to get some asprin, but only had an Advil Liquid Gel. So I chose to try this method and it also worked. With only ONE liquid Gel capsule I let it dissolve into my mouth. With the saliva that accumulated in my mouth over the few minutes (3 - 5 min) I used the Advil to work as a mouth wash.... and Wa La... It worked. Thanks to the others as well. I can now feel comfortable again.

I want to thank all who took the time to post to this site about the aspirin paste for canker sores. About once a year a get a huge breakout on the roof of my mouth. About 5 days ago I could feel the itch and tingling on the roof of my mouth and today I was in a full blown episode. Pretty much my entire roof was bubbled and I was dying...I tried the peroxide to no avail..I came across this site and saw all the positive from the aspirin therapy and gave it a shot....5 minutes after application I was pain free......unbelievable...

Could almost cry with happiness....Thanks all who submitted
