Home Remedies for Canker Sores

Canker sores are small ulcers that appear inside of the mouth. Simple canker sores are common in people between the ages of 10 and 20 years old. They can occur 3 or 4 times in a year, but typically only last up to a week each time. Complex canker sores are sometimes found in people with other illnesses. They are less common, but mostly occur in people who have had canker sores before.

A number of conditions that cause irritation or injury to the mouth can contribute to the development of canker sores. A few of the most common causes include:

• Injury from braces
• Injury from a sharp tooth
• Injury from a sharp dental instrument
• Poor fitting dentures
• Stress
• Food allergies
• Hormonal changes (particularly in women)

• Crohn's disease
• Celiac disease (also known as gluten intolerance)
• Weakened immune system
• Nutritional deficiency (especially if deficient in iron, zinc, folic acid or vitamin B12)

Canker sores appear on the inside of the mouth on the tongue, inner cheeks, inner lip or gums. Sometimes, before an ulcer erupts, a person may feel a tingling sensation in the area where a canker sore ultimately appears. Once a canker sore is present, it will appear as a round, gray or white ulcer that is sometimes outlined in red.

In the case of complex canker sores or a severe case of simple canker sores, a person may experience a fever, severe fatigue and swollen lymph nodes.
