Canker sores and facts you may want to know!


Doctors haven't yet determined how people inherit the tendency to get cankers also known as Aphthous Stomatitis. As the cause is not completely understood, it is said that it may involve a T cell mediated immune response which is triggered by a variety of factors and different people have different triggers.


Cankers are common in women who are menstruating and students due to an increase in stress levels. Low levels of vitamin B12, iron, and folic acid may also be triggers. Allergies can also produce an increased risk.


Canker sores appear as round, white spots with red borders, varying in shapes and sizes. Usually, they appear on the inside of the cheeks, on the tongue, and inside of the lips. In rare occasions, they may appear on the roof of the mouth or gums. Healing time can be anywhere from 1-2 weeks, depending on the size. Large cankers may leave scaring.

Canker sores may cause pain that can last 4-10 days. In severe cases, some people may experience fever, sluggishness, and swollen lymph nodes. Pain may worsen when sores come in contact with acidic and spices foods. 

Prevention and treatment

Pain associated with cankers normally subsides after a 4-10 day period without any medication. Rinsing your mouth out with salt water may alleviate the pain. If you experience frequent recurrences you may wish to see your doctor who may prescribe a tetracycline rinse. Avoiding irritants such as citric fruits, acidic vegetables, and spicy foods may reduce recurrences.  Also, avoiding irritation from gum chewing and brushing your teeth with a soft bristle toothbrush can help avoid triggers.
