I have had painful canker sores (not cold sores) on and off for about six months. Sometimes it's so painful I can hardly eat. I went to the doctor and she could not figure out what the cause is. I'm in general good health, at least from what I know, and I have a well balanced diet. Maybe it's still could be vitamin or mineral deficiency?...

Does anybody know what causes this???? :confused:

Has the doctor called them cancer sores, do you mean that?.

I had mouth ulcers years ago, quite a lot in fact, it turned out to be a side affect of HRT I was on for a short time, never again!!!!.

Try cutting back on fruit, acid from them can cause mouth ulcers. Have you had a blood profile done are you anaemic?. If you are run down you could be prone to illnesses and weakened immune system.

I believe cancer sores and mouth ulcers are the same thing. I haven't had my blood work done lately. I doubt I'm anemic, though, because I feel very energetic and I'm the one not catching a cold when everyone around me are sick. So, this is what confuses me so much. I've tried everything, even changed tooth paste (I did get better for a while after changing, but it came back after a few months ) You said something about fruit consumption and I guess that's something I've not tried to cut back on...It's so gooood...how can I do that?

Try cutting out acidy fruits like oranges, lemons that sort of thing. Why not try vegan yogurt to try to neutralise the bacteria?. Your dentist may give advice.

I am sure someone on here may come up with a herbal remedy why not ask Manish (let-me view) he comes up with some good ideas?.

Too much baby corn will give me mouth ulcers, also some people find chocolate can bring them on.
Make sure you take a daily multivitamin in case you're low on something.

The ones I'm familiar with are cold sores. The "cold" here is a herpes virus, simplex one if I remember correctly. Just about everyone carries these around and they will pop up on the gum tissue seemingly spontaneously due to stresses of some kind or other.

The varichella virus is another one of these that inflicts huge numbers of people, usually not until fifty or so. It is the re-emergence of the dorment chickenpox virus that remains in the spine of anyone who has ever had the disease. I had a very serious attack of this herpes zoster or shingles last year. Some of the nerves on my left shoulder and neck are still not fully recovered. Very evil looking but not contagious to anyone who has ever had chickenpox.

Zoster outbreaks are mysterious. They effect approximately 25% of the population, usually the elderly. I can only speculate what allowed mine to happen. A compromise of the immune system. Probably reduced activity, weight gain, and poor diet.

There is no cure because these are viruses. New drugs can sometimes suppress early outbreaks. There are three common forms. The most common is the cold sores that started this topic. Second is zoster, and third is the sexually transmitted version, although this one may eventually move up to second.

Cold sores are common, stress related, and nothing to be concerned about. I've had them so bad I almost couldn't eat. None since the zoster outbreak. I'm hoping my immune system is stronger now and keeping all these suckers at bay.

On my natural first aid remedies; Chew ginger root, myrrh oil mouthwash and lavender oil mouthwash these are recommended for mouth ulcers.

Yes, like others have said, it's because of acidy type foods, like citrus fruits and I also find eating a lot of ketchup or pickles (stuff with a lot of vinegar) give me canker sores.

But I get mostly cold sores on my lips. I find stress and the weather brings those on, so maybe a lot of stress is causing your cankers...?

L-Lysine. Tea Tree oil. Goldenseal. Calendula. ;)

So...I was wondering if anyone had some input for this. I've had this nagging canker sore for about 2 weeks. This is very unusual for me, since in the past I've only had a couple canker sores when I've been really stressed (school). Right now life is good and I'm not stressed so why the heck do I have this!?! Is it because I've been drinking too much juice? Am I lacking in some mineral/vitamin? I've only been vegan for about....3 months? So I've been keeping a pretty close eye on myself to make sure I'm doing everything right. Does anyone have an idea?

Maybe you bit yourself while sleeping or eating and didn't notice and now it's getting bad because of the acids in your food?

I'm not sure what causes canker sores other than stress.

Cracks at the corners of the mouth are a sign of vitamin B2 (riboflavin) deficiency.

I also get canker sores, well i call them mouth ulcers and they are inside the mouth, on inside of lips, gums or tongue.

They turn up before PMT hits me.....right now i have 4 in my mouth; they just appear out of the blue at this time. They are very painful and i can hardly speak, let alone speak clearly. lol maybe my bf is lucky i get these.

I am trying to take evening primrose oil and flaxseed oil - because i was not taking these which is naughty.

I tried tea tree oil mouth wash and putting this onto the ulcers.....I tried this twice before with them but it is not helping as much this time around.

This time around they have been bad and nothing is helping so i am taking chemist ulcer stuff, lozenges which are actually helping a lot to numb them and clear them up. I dont like taking these though...

I am feeling kind of sick with them this time, sore jaw and feeling glugged up and not well.

I also read somewhere that a deficiency in L-Lysine can cause mouth ulcers. And i see someone here says that also! So i will try and get some when possible and see if that helps

Canker sores are most commonly due to deficiencies in B12, Zinc and Folic Acid. About two weeks after I decided to go Vegan, I developed 6 at once - talking and eating was a nightmare. So with nothing exciting to do at work, I read a lot about it on the web, then went straight to Holland an Barrett and bought B12, Folc Acid and chelated Zinc. After a three days on the supplements the sores started to go down, then a week later they were gone, and I haven't had any since.

This link was useful:

Hope you feel better soon, I know how annoying ulcers can be!

I still get canker sores every two weeks or so...It's so painful and I also feel run down when I have them...I don't know what to do next, I've tried every thinkable remedy, but without any luck. Right know I have two under my tongue, which makes it hard for me to speak. I even joined a forum www.mouthulcers.org LOL.

I've been getting canker sores for most of my life. cold sores I think mine are cold. There's no cure for the type I have, they're given by kissing somebody with them and they're related in some small way to herpes. Mine come and go with health problems, when I'm weak or stressed they come up, when I'm getting dental work done they seem to crop up, when I've got an infection or cold of any kind.

Make sure you find out WHICH kind of mouth sores exactly you have, and check back with the doctor regularly. :3 Sometimes he/she can perscribe a mouth gel like orajel for the sores for pain and prevent infection.

As many of the others have said, it could be a deficiency of L-lysine or the B vits. Or stress. Or allergies. Citrus fruits can make it worse, as has been pointed out. Not enough iron, perhaps. A change of toothpaste has been mentioned but what about the toothbrush? Don't use a hard one. Soft ones are best. The old acid/alkaline balance.

Wet tea bags can be helpful as a poultice, if the sores are accessible. Or you could swish tea around in your mouth.

There is actually a herb called canker root. American Indians used it for canker sores.

Ask your doctor if you could use Metronidazole to fight canker.

Cold sores on the lips are a form of herpes called herpes simplex. Nothing to get too excited about because the majority of the population has them.
However, NEVER perform oral sex while you are having an outbreak, nor recieve oral sex from someone who has an outbreak. Dr. Drew says that they can be spread to the genitals. Spreading herpes simplex to the genitals does not mean that you now have "The Herpes" (as grandma might say) it simply means that you have herpes simplex on your genitals, which would be just as painful as having them on your mouth.
This girl I work with was telling me the canker sores or mouth ulcers (in the mouth) are another type of virus related to the herpes virus. I am not sure if this sure true.
