Canker sores, or medically aphthous ulcers, are small shallow lesions found only inside your mouth.  Canker sores are fairly common, 30% of all people will have a canker sore at some point in their life.  Anyone can get a canker sore, however, 10 to 20 year olds are more susceptible to having canker sores.

Canker sores are not contagious.  Canker sores are also not cold sores.  Cold sores (also called fever blisters) appear on the lips and are caused by a virus and are extremely contagious.  Cold sores typically appear outside the mouth.

Cankers sores are white or yellowish ulcers surrounded by red.  Usually small but can be up to an inch in diameter.

The good news, canker sores generally heal on their own in a week or two.  The bad news, they hurt and can make talking, eating or drinking a real pain.

 

Causes Of Canker Sores:

One of the most common causes of canker sores seems to be stress.

  • Emotional Stress.
  • Dehydration
  • Physical trauma to your mouth.  Accidental cheek biting or getting hit in the mouth.
  • Toothpaste or mouthwash that contains sodium lauryl sulfate (SLS).
  • Food allergies:  spicy foods, acidic foods, oranges, strawberries, eggs, nuts, cheese, tomatoes, chocolate or coffee.
  • Genetics
  • Hormonal Shifts
  • Recent bacterial or viral infection. Or a compromised immune system.
  • Medical Conditions – Inflammatory bowel, Crohn’s or HIV
  • Some medications – beta blockers, nicorandil or chemotherapy drugs.

 

Treatment for Canker Sores:

There is no cure for canker sores only treatments to help with the symptoms.  Canker sores generally heal on their own in 10 days.  If canker sores keep reoccurring it could be a sign of a medical condition and you should see your doctor or dentist to get some professional help.

If you have canker sores accompanied with fever, swollen lymph nodes or lesions that will not heal get medical help!
