Canker sores, also known as aphthous ulcers<\/strong>, are a type of open sore that appears inside the mouth.\u00a0 According to some, the cause is unknown, but sometimes there is a clear cause.<\/p>\n

In this article we will look at what a canker sore is, what it is not, and some possible causes.\u00a0 If your canker sores are triggered by one of these causes, then you have a good chance of eliminating canker sores.<\/p>\n

A canker sore is a painful open sore that appears in the mouth.\u00a0 It may be on the lips, side of the mouth, back of the throat or under the tongue.\u00a0 It does not appear outside the mouth.\u00a0 A typical canker sore is a couple of millimeters across, with a white bottom and an inflamed red rim.<\/p>\n

This is not to be confused with a cold sore (herpes simplex 1) which appears as blisters around the outside of the mouth.<\/p>\n

Canker Sore Causes<\/h2>\n

The cause of a canker sore or aphthous ulcer is not known, but there are a number of possible causes.\u00a0 These include:<\/p>\n

\n
• A small injury, such as biting the inside of your mouth<\/li>\n
• A reaction to citrus fruits<\/li>\n
• Vitamin b12 deficiency<\/li>\n
• Iron deficiency<\/li>\n
• Folic acid deficiency<\/li>\n
• Chemotherapy<\/li>\n
• Behcet disease<\/li>\n
• Crohn’s disease<\/li>\n
• Food allergies<\/li>\n
• Immune system reactions<\/li>\n<\/ul>\n

  The above is not an exhaustive list, but it does give you the idea that there are many possible causes of this condition.\u00a0 On the other hand, a particular condition does not always produce a canker sore.<\/p>\n

  Allergies and Canker Sores<\/h2>\n

  Some people with food allergies get a canker sore as one of their symptoms.\u00a0 Some people have reported this as a symptom to nut allergies for example.<\/p>\n

  Allergies as a cause of canker sores can be hard to pin down.\u00a0 If your allergic reaction is delayed, you may not make the connection with your symptoms and the food causing it.\u00a0 Not all symptoms may appear at the same time.\u00a0 Knowing this is the case, watch out for it.\u00a0 You may discover that canker sores go away when you stop eating certain foods.<\/p>\n

  One study did show that a cow’s milk allergy can often cause canker sores.<\/p>\n

  Canker Sores and Toothpaste<\/h2>\n

  Some types of toothpaste can cause canker sores for some people.\u00a0 One reason is a common ingredient ( sodium laurel sulfate, see below) and another seems to be more specific to the types of toothpaste formulated to handle sensitive teeth.<\/p>\n

  Canker Sores and Sensodyne<\/h3>\n

  If toothpaste such as Sensodyne is the cause, you may be better to have a dentist look into the cause of your sensitive teeth, and quit using the Sensodyne.<\/p>\n

  The ingredients in Sensodyne are as follows:<\/p>\n

  \n
  • Potassium nitrate<\/li>\n
  • Sodium fluoride<\/li>\n
  • Strontium chloride<\/li>\n
  • Strontium acetate<\/li>\n
  • Potassium chloride<\/li>\n
  • Titanium dioxide<\/li>\n<\/ul>\n

    Sodium Laurel Sulfate<\/h2>\n

    Sodium laurel sulfate, a foaming agent, may be another cause of canker sores.\u00a0 This is found in many brands of toothpaste.\u00a0 If this is your problem, you will have to find a ‘natural’ brand of toothpaste (note that toothpaste is not natural, it has to be manufactured!).\u00a0 Read ingredients carefully, the word natural<\/em> is totally meaningless in the world of marketing.<\/p>\n

    Sodium laurel sulfate is also known as:<\/p>\n

    \n
    • Sodium dodecyl sulfate<\/li>\n
    • SDS<\/li>\n
    • NaDS<\/li>\n
    • Sodium laurilsulfate<\/li>\n
    • SLS<\/li>\n<\/ul>\n

      Conclusion<\/h2>\n

      There are many possible causes of canker sores.\u00a0 One is allergies or chemical sensitivities.\u00a0 If you get a lot of canker sores, pay attention to what you eat and how that correlates to your canker sores.\u00a0 With luck you can find the link, eliminate the food or chemical, and live (mostly) canker-sore free and allergy-free.<\/p>\n
