Cankers sores, sometimes called aphthous stomatitis or aphthous ulcers, are tiny but rather painful breaks in the skin inside an individual’s mouth. Canker sores can cause significant amounts of pain and can adversely affect the quality of life of patients. But what are some of the causes of canker sores? In this article, we will look at the possible causes of canker sores and what individuals can do to alleviate the pain associated with canker sores.
Canker Sores: a Brief Overview
Canker sores are one of the common lesions of the mouth encountered by people from all walks of life. Women are more likely to develop canker sores than men. It is also possible that some people may also have a genetic predisposition to developing canker sores compared to others
Canker sores can present themselves in the different areas of a patient’s oral cavity such as the cheeks, throat, and lips. Canker sores can appear as white, yellow or gray spots framed by a red swollen circular border.
What Are Some Types of Canker Sores?
Cold sores are different from Canker sores. Cold sores or fever blisters can be brought about by an infection caused by the herpes virus and can be passed on from one person to the next. On the other hand, canker sores may not be passed on to other individuals or in short, they are not contagious. Canker sores can also be categorized based on the following:
Minor sores (3-10 millimeters in size)
These minor canker sores are some of the most common types of canker sores and will usually resolve on their own after two (2) weeks without leaving any scars after healing
Major sores (more than 10 millimeters in size)
Major canker sores are generally bigger and deeper than minor canker sores. These kinds of cankers sores may take longer to heal, have jagged borders and may leave a scar after being completely healed.
These canker sores are usually small in size but may appear as clusters made up of 100 or so canker sores. Fortunately, this kind of canker sores heals without any trace of scarring.

When to Contact your Doctor or Healthcare Professional
While canker sores are not usually a cause for major concerns, there are a number of possible reasons that may warrant some form of coordination with the patient’s healthcare professional or doctor.
Individuals are advised to contact their doctor for further medical assistance if they observe canker sores that go hand in hand with fever, when canker sores are already preventing people from hydrating by making it difficult or painful to drink fluids, once Canker Sores still exhibit or give out tremendous amounts of pain even after taking pain relievers that are over-the-counter (OTC), if and when the canker sores have lasted for more than three (3) weeks, if the patient determines that the canker sores are spreading and if the patient notices that the canker sores are spreading.
However, canker sores generally do not need any major treatment. Certain topical medications, mouthwashes and pain relievers can already address the more serious adverse effects of regular canker sores. Aside from these topical solutions, patients may also avoid certain food items such as spicy foods or citrus fruits to prevent the worsening of canker sores.
