Why Do We Get Canker Sores?

June 19, 2019 | Posted in Education

Canker sores are small, shallow ulcers that appear in the mouth and can make simple tasks such as talking and eating uncomfortable. Canker sores are typically caused due to stress on the soft tissue inside the mouth.
Consuming acidic or citric food and drinks such as oranges, lemons, strawberries, pineapple, and soda can trigger and even worsen canker sores. Canker can also be caused by any of the following:         

  • Diet lacking in zinc, vitamin B12, iron, or folate acid.           

  • An accidental cheek bite.

  • Emotional stress.       

  • A response to an allergic reaction.    

  • Hormonal stress during menstruation

Many different diseases including celiac, Behcet’s, and Crohn’s disease can also cause frequent canker sores. Unfortunately, there is no cure for canker sores. However, you can take measures to reduce their frequency. Try to avoid foods that irritate your mouth, and avoid chewing things like gum that may cause you to accidentally bite your cheek. If you find that you have canker sores that are unusually large, spreading, or last more than three weeks, it is recommended that you contact your dentist.
