Can Stress Cause Canker Sores

Can Stress Cause Canker Sores?

Canker sore outbreaks seem related to physical or emotional stress.

There have been small studies done to look at the role stress, anxiety, and depression play in the development of canker sores or recurrent aphthous stomatitis (RAS), which are canker sores that form often.

Researchers from a study from the Journal of Oral Pathology and Medicine determined that there appeared to be a link between canker sores and stress.

A small study in Contemporary Clinical Dentistry evaluated the psychological profiles and salivary cortisol levels that indicate stress of people with RAS. The researchers were able to conclude that the levels of anxiety and depression were higher in people with recurring canker sores.

While stress, anxiety, and depression can cause canker sores there may be other causes for why you’re experiencing canker sores. They include:



  • Minor mouth injuries
  • Toothpaste and mouthwashes containing lauryl sulfate
  • Food sensitivities
  • A diet lacking vitamins and nutrients
  • Allergic reaction to certain bacteria in the mouth
