Canker Sores: Causes and Treatment

Canker sores are small shallow ulcer or lesion that can develop on the inside of your lips, soft areas inside your mouth or at the base of your gums. Unlike cold sores, canker sores are not contagious and don’t present themselves on the surface of your lips.

However, getting a canker sore can be cause for many days of pain or discomfort and distraction. Depending on their location, some canker sores can make eating or speaking more difficult.

One may wonder where these ulcers come from and what can be done about them.

The Five Most Common Canker Sore Triggers:

  1. Eating highly acidic foods, such as pineapples, tomatoes, lemons, or strawberries can be tough on the soft tissues of the mouth and cause a canker sore reaction.
  2. The strain on one’s immune system from being ill may increase the likelihood of getting a canker sore.
  3. Biting the lip or inside the cheek can cause tissue injury. When it swells up during the healing process it becomes more likely to be bitten accidentally again.
  4. Prolonged periods of high stress put a strain on the immune system, which, in addition to other factors that may develop, makes the mouth more vulnerable to developing sores or lesions.
  5. Braces or improperly fitted dentures can lead to canker sores, if they rub against the inside of the cheeks or the gums.
