Canker Sores

Did you notice any small round white or yellow sores surrounded by red area inside your mouth? If yes, then they are called canker sores. They usually appear on the loose tissues of the mouth, like inside of the lips or cheeks, under the tongue, and sometimes near the tonsils.

It usually takes about a week or 2 weeks in some cases for these sores to heal.


Some experts say canker sores are inherited and a theory says it may be result of body’s immune system.

They can also be caused due to injury in the mouth for example bite or a cut, toothpastes that contain sodium lauryl sulfate, emotional stress, hormonal changes, food allergies, vitamin deficiencies especially vitamin b, folic acid, iron and selenium. However, canker sores are not contagious.


  • Applying over-the-counter remedies that contain numbing agents, like benzocaine or phenol.
  • Rinsing with salt water or an antimicrobial mouthwash.
  • Avoiding spicy or acidic foods during an outbreak.
  • Working with a healthcare provider to treat any food allergies.
  • Taking a daily multivitamin.

We recommend medication if the sores are large and painful.
