Cancer Sores (also referred to as aphthous ulcers) are irritations which develop inside the mouth. Though often confused with cold sores they are inherently different. Cold Sores commonly form on the outside of the mouth and can be contagious, while canker sores are found inside the mouth and are not considered contagious at all.

A canker sore is a shallow sore that appears on the inside of your lip, cheek or tongue. They most often have a red border which surrounds a white or yellow center and can be painful at times.  The places where canker sores can appear are:

  • On the tongue
  • On the insides of the cheeks or lips
  • On the roof of the mouth
  • On the base of the gums

Canker sores are often found in adolescents and young adults. In fact, it is said that 20% of Americans are afflicted by canker sores. However, women are more likely to be afflicted than men are. People generally receive their first canker sore between the ages of 10 and 40.

There are three different types of canker sores

1. Simple canker sores (Minor Aphthous Somatitis)

Simple canker sores can appear three to four times a year and last up to about week. They typically occur in people between 10 and 20 years of age and are the most common form of canker sores.

2. Complex canker sores (Major Aphthous Somatitis)

Complex canker sores are less common and occur more often in people who have previously been afflicted by them in the past.

3. HerpetiformAphthous Somatitis

This is the least common form of canker sores. It occurs in less than 5% of people with canker sores.

What cause canker sores?

A lot of people wonder how you get canker sores in the first place. The true cause of a canker sore is not known, but the theory is that it can be induced through stress or tissue injury. Some acidic or citrus foods and vegetables like oranges and tomatoes may make canker sores worse or possibly even trigger them. Though there is no way of knowing what are the direct causes of canker sores, there are several factors which promote canker sore growth:

1. Stress Induced
2. Tissue Injury
3. Hormonal Changes
4. Dietary Influences
5. A Broken Tooth

Some dental appliances like braces could also trigger a canker sore, as well as maybe a sharp tooth.

Health conditions can also remote canker sores such as nutritional problems, impaired immune systems, iron deficiency or a gastrointestinal tract disease like Chron’s disease.  Nutritional deficiencies like the absence of b-12, zinc or folic acid may cause or trigger them as well.

Symptoms of canker sores

The first stage of a canker sore initially begins with a burning feeling within your mouth. It is commonly accompanied with inflammation and pain during eating or talking. The most noticeable symptom of a canker sore is a white or yellow ulcer surrounded by a red border.

Some of the other symptoms include:

  • Burning sensation in the mouth
  • Small ulcers throughout the mouth and usually last up to ten days. These are surrounded by a red border.

Minor cases of canker sores can be sorted out in 1 to 3 weeks. Generally speaking the pain will last from one week to ten days, but major cases can take up to 6 weeks to heal.

Some of the less common symptoms associated with canker sores are:

  • Fever
  • Discomfort or uneasiness
  • Inflamed lymph nodes
