Canker Sore Symptoms

Canker sores are usually quite easy to spot even without seeing them in a mirror. They are often a small lump inside the mouth on the gums, the soft palate, the inside cheeks or on the tongue.  It will likely be big enough for you to notice when you run your tongue over it. When you touch it with your tongue or a finger you will notice a sharp pain.

The look of a canker sore inside your mouth is usually a small round sore either white or gray in color. The white or gray area will be surrounded by very sore skin usually a bright red color.

Some people might suffer from severe canker sores in which case the above symptoms and the overall pain will be much more prevelant. Severe canker sores might also cause exhaustion, swollen lymph nodes and even in extreme cases a fever.


How to prevent canker sores?

This site already covers canker sore treatments but it is perhaps more important to look at methods of preventing canker sores so you do not have to go through any canker sore pain again.
It is not scientifically known what causes canker sores or why some people seem to develop them more often than others, but there are things in common with many people who get canker sores.
One thing that seems to cause them for a lot of people is doing something to your mouth (gum or tongue) that results in an injury. This might be burning your mouth on a drink or food that is too hot – this will cause a burn that might turn into a canker sore. Personally I get a lot of canker sores from burning my mouth and the burn turning into a sore the next day. The same thing applies to biting your tongue or your gum – any small cut might turn into a canker sore.

The best way to avoid the above is to be careful with your food – don’t put it in your mouth if it is too hot.

Canker Sore Treatment

Canker sores can be very painful and annoying, and the more often that you suffer from them the more you will want to find an effective canker sore treatment. What works for one person might not work for everybody though, so if at first you don’t succeed, try and try again!


Canker Sore Remedies


Swap your toothpaste ! If you are using a toothpaste that contains sodium laurel sulphate, it might be causing or at least aggravating your canker sores. There are plenty of  toothpastes around that do not have any sodium laurel sulphate and you might find that this helps


Rinse your mouth with salt water. To do this, use slightly warm water mixed with salt. Rinse well and repeat if necessary. Then rinse with a peroxide (check with you chemist first for a suitable peroxide) and then rinse again with water. This should help numb the pain.


Put salt on the wound. This is a very painful solution but rubbing salt into the sore and leaving it there for 5-10 minutes. This will both cause pain and healing! The pain will last for about 20 seconds and after the the healing should begin. Many people have told me that the next day their canker sore was on the mend, or already almost gone!


Use a strong mouthwash. Mouthwashes  can really help to kill the bacteria in the canker sore and help the healing begin. Like putting salt on the sore using mouthwash can be a painful experience  but it should help you on the road to recovery. If you don’t want want to rinse with mouthwash what you could do is dip a qtip into a small amount of mouthwash and then rub it gently over your canker sore.


Some people swear that putting baking soda for two minutes on your canker sore can help to both relive the pain quickly and to help it heal quickly. Then rinse your mouth with warm water.


Put a wet tea bag in your mouth (try and get it onto your canker sore) and leave it there for as long as needed. After a period of time the pain of the canker sore should start going down and you can remove the tea bag.


Here is one that you should not do too often! Get 1 asprin pill and put it on your canker sore. After a while the aspirin should dissolve into it. Rinse out your mouth with warm water. This will numb the pain very effectively. Now you can apply salt directly to it without suffering too much pain. After 20 seconds or so of having the salt on the sore, rinse your mouth out with warm water. You can repeat the salt part of this whenever you need, but do not use aspirin pills very often (1 a day should be enough!).

What is a canker sore?

A canker sore is a very painful sore inside the mouth. It is also known as an aphthous ulcer (or just a plain mouth ulcer in some countries, such as the UK). As anybody who has ever suffered through them can attest, they can be very irritating and painful and depedning on where exactly it is located can make swallowing or eating painful. Canker sores are suffered by over 80% of the population at some point in their life and many people have them recurring often. In fact 10% of the US population has recurring canker sores – many of which find that there family has a history of them. They are most commonly found on the gum – usually just behind either the top lip or the bottom.


For such an annoying, painful and frequent condition it is incredible that so little is actually known about them. We will go into some details of possible causes and treatments soon, but both can vary depending on the person. There is really no known reason that a person might develop ulcers or have them recurring (except for them being hereditary).


If you a regular sufferer of canker sores the first thing to do is try and prevent them from occurring. This is of course is very difficult without knowning the causes of canker sores. The fact the the causes might be different for you than for anybody elese does not help of course, as the way somebody else has elimintated them might not work for you! So how do we go about eliminating canker sores? I have found that most people get canker sores from either a diet related condition or stress/lack of sleep. The best way to find out how you get canker sores is to keep a diary of your day as far as sleep patterns, stressful days and the food you eat goes. Very soon you might find a pattern emerge and it might be that lots of late nights result in a sore appearing either the next day or perhaps even a few days later (which is why it has been so hard to identify your cause!). You might find it is a result of being very busy with your studying or at work.


If it is not a sleep or a diet related condition it might well be related to foods you are eating. I have had a couple of friends who have found that lowering that salt and sugar levels has completely stopped their ulcers appearing. It is very much worth keeping not of what kind of foods you eat – too much fruit might cause them, not enough fruit might cause them. You will really have to do some hard work to determine why you are getting them.


Treatments for canker sores varies and just because one treatment works for somebody, don’t expect it to work for you. However, aesthetics such as paracetamol can at least numb the pain and make the ulcer more bearable. There are specialised anethtics that are meant just for ulcers and you can rub them on to the inflamed area. These are very good and numbing hte pain and allowing you to eat as you otherwise would.


A canker sore usually last around a week to two weeks, but they can last three or four. If you have an ulcer last any longer than four weeks it is time to go see the doctor so that they can make sure it is nothing more serious.
