Canker sores and cold sores are infections that occur on, around or inside the mouth. While they have similar symptoms (pain and discomfort while eating and talking) and are often confused with one another, these two maladies of the mouth are distinctly different and it’s important to note that difference in order to get the best treatment for each.

What’s the difference?
A canker sore is a small, white or milky gray ulcer surrounded by red, inflamed tissue; it’s found on the inside of the mouth. A canker sore can be caused by stress, tissue injury, hormones or severe fatigue. Canker sores, unlike cold sores, are not contagious.

A cold sore, sometimes referred to as a fever blister, is a painful, fluid-filled blister found on the outside of the mouth, typically on the lips. Cold sores are caused by the Herpes virus and are triggered externally by stress, fatigue, or external exposure to extreme conditions. Cold sores are extremely contagious.

What are the symptoms of a canker sore?

  • Tingling or burning sensation inside the mouth
  • Sores inside the mouth, including on the tongue, soft palate or inside of the cheeks
  • Small, white or gray ulcers with a red border
  • Fever, swollen lymph nodes and lethargy (severe cases)

What are the symptoms of a cold sore?

  • Small, fluid-filled blisters around the lips, mouth and gums
  • Raised, red, painful blisters around the lips and mouth
  • Broken, oozing blisters around the lips and mouth
