Natural Home Remedies For Canker Sores You Must Know

Canker sores also called aphthous ulcers, are small, shallow lesions that develop on the soft tissues in your mouth or at the base of your gums. Unlike cold sores, canker sores don’t occur on the surface of your lips and they aren’t contagious. They can be painful, however, and can make eating and talking difficult. Most canker sores go away on their own in a week or two. Check with your doctor or dentist if you have unusually large or painful canker sores or canker sores that don’t seem to heal. We also came up with some of the best and easy to try home remedies for canker sores that everyone suffering must try.


The precise cause of canker sores remains unclear, though researchers suspect that a combination of factors contributes to outbreaks, even in the same person.

Possible triggers for canker sores include:

  • A minor injury to your mouth from dental work, overzealous brushing, sports mishaps or an accidental cheek bite
  • Toothpastes and mouth rinses containing sodium lauryl sulfate
  • Food sensitivities, particularly to chocolate, coffee, strawberries, eggs, nuts, cheese, and spicy or acidic foods
  • A diet lacking in vitamin B-12, zinc, folate (folic acid) or iron
  • An allergic response to certain bacteria in your mouth
  • Helicobacter pylori, the same bacteria that cause peptic ulcers
  • Hormonal shifts during menstruation
  • Emotional stress

Canker Sore Vs Cold Sore

You might have known about canker sores and their symptoms above, so here is a bit of information about cold sores.

Cold sores, or fever blisters, are small fluid-filled sores that usually occur in clusters. These painful blisters often appear on the nose, lips, or anywhere around the mouth.

You might feel a tingling sensation on your skin before a cold sore appears and in about two days the cold sore is developed. Later, it breaks and oozes, leaving a crust-like layer over the blister. Unfortunately, they take two to four weeks to heal, leaving you with an unattractive scab on the affected area.
