Canker sores in your mouth can be quite painful, but can be easily treated with household remedies. This is a guide about remedies for canker sores.
The best way to clear up a canker sore is truly putting baking soda directly on it. I went to the doctor with a mouthful of canker sores and they didn't have a clue. The sores were so bad I couldn't even eat or talk. I decided to burn those suckers off with baking soda and within two days they were gone! Love my baking soda. It does sting, but if you keep applying until it doesn't sting anymore, it will feel better.

I have canker sores often and have used may different home remedies, over the counter medication without great success. A friend told me to rinse the area with lemon juice. It stings at first, but after several times of rinsing throughout the day, the sting lessens, and the canker sore healed much faster.
I always have lemons on hand, so do not have to run to the store when a canker sore starts to rear it's ugly head. Try this it really does work.

I have several little blisters on my top lip that are very tiny, as well as, what I think are ulcers or canker sores inside my cheek and bottom inside of my lip, like 4 or 5! I don't know what they are or what causes them.
I've had cold sores before and they usually disappear within a few days to a week, but this time it's been about a month on and off. I am really stressed. What do I do?

Honey mixed with ceylon cinnamon works for me. take about a 1/4 tsp a couple times a day and keep it in your mouth as long as possible. Cheap and tastes good.
To cure a canker sore, dip a Q-Tip in Pepto Bismol. Place Q-Tip directly on sore. It is very cool and soothing and will heal the sore within a day or two. It is safe to swallow any excess Pepto or you can spit it out, but it's better to swallow it because chances are your stomach is or has been upset too and the Pepto will help it, too.
You can even use the Generic Pepto from Dollar General or Wal-mart. You may need to repeat this two to three times a day. Usually by the second day, it's not sore anymore.
Source: I am a retired nurse and one day I tried it because I have always used Pepto-Bismol for stomach upsets.

As a dietitian, I am a firm believer in that most of our health problems stem from what we ingest. I have always suffered from (what I thought) was sporadic flare-ups of canker sores. I have heard numerous theories about what causes them and so I never really tried to connect the dots with food until recently. I figured since everything else was out of my control (like viruses, genetics, etc) then maybe, just maybe, I had been doing it to myself, so I decided to keep a food diary for 1 year. Also, every time a canker sore began to appear, I noted it in the food diary. It actually didn't take very long before I noticed strong correlations between my flare-ups and certain thing I had eaten within the past few days!
There were 2 specific things that, if eaten/ingested, almost always seemed to be followed by canker sores: alcohol and anything tomato related. So I decided to test this correlation by first removing alcohol entirely from my diet for 3 months. Nothing changed. I still had flare-ups at least once a month like I had always had.
Here is where things got interesting. I turned my focus toward tomatoes and anything with tomatoes in it. This was very difficult for me because I love tomatoes, and I put ketchup on many things. However, I dedicated myself to this big task and began another 3 month test. No tomato slices, no ketchup, no red pasta sauce, etc. The difference was noticeable almost immediately. After just a couple of days, I noticed that my gums felt "less sensitive" to the touch. I never even knew this was abnormal because they had always felt sensitive, but suddenly they felt better!?
I knew I was on to something at this point and I have continued this difficult elimination even beyond the 3 months. I have now gone 7 months without anything tomato-related in my diet and I have since had just 1 canker sore! Also, I got the sore when I caught a nasty head cold about a month ago.
I never would have considered something as healthy for you as a tomato as the source of what had made my life miserable since childhood. Whether it is the acidity or something else that my body just has trouble with, I'm not entirely sure. It could be a weird food allergy, but all I know is that I found the trigger for my life-long problem with canker sores and eliminating it from my diet has helped me tremendously.
I can't guarantee that it will be the same for you, but I encourage everyone who has issues with these pesky sores to look into removing all things tomato from your diet for a while and see if your flare-ups reduce. It was very difficult to totally eliminate tomato since it is in so many products, but if you watch your diet closely it gets easier. It has helped me tremendously so I hope it helps you too.

I find drinking pineapple juice is good for all mouth sores. (03/17/2010)

My 5 year old gets canker sores occasionally and when he does, brushing his teeth is horrible. He usually doesn't say anything until teeth time. I've tried putting some remedies on it and it's horrible for him.
He doesn't get them enough for us to change diet, it's occasionally. I am looking for something that he can rinse with to help speed up the healing process and take away some of the pain. Thanks.
Bless his little heart! I feel his pain, so, I recommend ABREVA. It's expensive, but it really works and only takes a small squirt 5 times a day and the sore goes away faster than anything I've tried in the past, (soda, etc. - ouch - Burning!). You didn't say what age, so ask pharmacist. Hope this helps the little one! Maw-Maw (01/09/2010)
Gargle with a solution of baking soda and water, tastes awful but helps neutralize the acid. And you might want to check the sugar that he is getting, believe it or not, a lot of sugar in a diet can cause canker sores. Believe me, it's from experience! (01/12/2010)
Poor little guy. Canker sores are so painful!
But maybe there's something you can do to prevent them. I found out after many years of suffering. My dentist wasn't any help. Just told me that a lot of people suffer from them.
So I did my own research and discovered a simple explanation! Many people are sensitive to one of the chemicals found in most toothpastes! That chemical is a detergent called "sodium lauryl sulfate," also called "SLS." It's the ingredient that makes toothpaste (and soap and shampoo)"foamy."
It's extremely drying to mouths that are sensitive to it, and causes mouth ulcers and canker sores to form. Unfortunately most toothpastes include SLS in their formulas, even the "natural" brands. Just check the labels - it's almost always in there.
But during my research I found that there are a few toothpaste that have deliberately omitted SLS because of the canker sore issue. I tried a couple of them. The one I liked best was "SQUIGLE Enamel Saver." The downsides are that you have to order it online, and it's also more expensive than regular toothpastes (about $7 and a few more bucks for shipping).
Rembrandt also makes an SLS-free version (I think it's called "Gentle Formula," but I found that one was so dry that it was hard to squeeze out of the tube!
Squigle worked so fast and so well to eliminate my canker sore breakouts that I realize I will always have to "splurge" on my toothpaste, or suffer the consequences!
I've been using it for about two years, and in all that time I've had only two canker sores! I got them both at the same time and it was when I was getting over the flu, so I think they were just from the stress of being run down for a couple of weeks.
As a person who has had canker sores at least once a month most of my life, and in recent years getting them almost non-stop, the SLS-free toothpaste has been a miracle! I sure wish they'd figured this out a lot sooner.
Maybe you could ask your dentist's opinion about trying it. (Mine was clueless, but that was a few years ago.) Good luck to you and your little guy! (01/12/2010)
If you could talk him into telling you when they are coming on I use a prescription called Clioquinol 3% Hc1% that works wonderful. It is a cream that has to be applied several tims a day and if I catch the sore when it is coming on it won't go ahead and come by using this cream. I cannot drink orange juice over one glass a month or so and have to watch high acid tomatoes also. I have had cold and canker sores for 50 years and this is the best treatment I have found yet. Good luck. (01/13/2010)
When my dd immune system went down she got them. Put hydrogen peroxide on it. Do not double dip q tip in it. Get it super wet and gently let it drop onto the canker sore. Have him watch the bubbles. Ria (01/13/2010)
Ora Gel will not cure the sore but it will numb it temporarily while he brushes his teeth. (01/13/2010)

Yes, peroxide diluted with water. (01/13/2010)
My husband has suffered his whole life until he found out about "Listerine" it works! He rinses after he eats certain foods like tomatoes or chocolate and it prevents them and if he does get one rinse at the first sign it they go away or shortens the duration! (01/13/2010)
If you have a doctor who will write a Rx for you, get it for kenalog in ora base. This stuff is amazing, just before bed, you dry the area and dap on a very small amount. Then go to sleep and the next morning the sore is gone, really gone. But the reason these things come in the first place is from digestion that's screwed up. It's probably from not enough hydrochloric acid production in the stomach. This was my problem. (01/13/2010)

I got these all the time when I was growing up, sometimes two or three at a time and they were horrendous and very painful!
My grandma told my mom to have me put ALUM on them. It's a pickling agent used to make pickles, sold in the spice aisle. It comes in a little jar and is a white powder. It does sting when you first put in on (and doesn't taste good either, very sour) the canker sore, but within seconds it numbs the pain and won't numb the rest of your mouth the way other pain relieving oral cremes can. It also works to heal the sore faster by protecting it and helping it to dry out. It always, always worked for me, and I've used it on my son when he gets them (although he's only had a few).
Abreva won't work - canker sores inside the mouth are not the same as fever blisters or cold sores. Other pain cremes just numb the pain and the rest of your mouth too!
I'd give this a try, it's a very old remedy. Surprised, actually, to see that someone hadn't already mentioned it. That's why I had to... Hope this helps! (powdered alum if you need more clarification but on the label it just says "Alum", which I just looked up on wikipedia and it says it's a common home remedy for canker sores!)
Also the jar lasts a long time.
To use, just wet the tip of your (clean) finger, stick it in the jar to stick some of the powder to your finger, then stick it on your canker sore. I used it as often as I wanted to, whenever the numbing effect wore off (which was a few hours or more) ~Jaidamoon (01/13/2010)
The easiest and most painless way to cure canker sores is by dipping a Q-Tip in Pepto-Bismol the hold it on the canker sore for a few minutes. It will feel cool and soothing. Do this 1-3 times a day for 1-2 day's and the canker sore will go away. You can swallow any Pepto that will be in your mouth with your saliva or you can spit it out. It is better to swallow it because this is what cures a sour stomach by lining the wall of your stomach. I am a retired nurse and have used this remedy on myself and my children for many years. It works great!

Try L-Lysine, in the Vitamin Aisle. My grandmother had me do this when I was younger. (01/14/2010)
My son had this problem for years. Turns out it was the toothpaste he was using (the red and white-striped one). We switched to Biotene - problem solved. (01/15/2010)
If you have a canker sore on your lip (or worse, on your tongue) you can help it heal within a day by putting a small bit of baking soda right on the sore.
I am 29 and have suffered since I was little. I get them once a month if I do not take preventative measures. The good bacteria found in natural yogurt is what works for me.
My 10 year old daughter has re-occuring canker sores. Anyone have a home remedy that actually works?
