Causes of Canker Sores

Once you better understand what some of the known causes of canker sores are; then you can begin taking steps to avoid the causes.
Immune System: We all know that our bodies are effective in fighting off viruses that can cause this condition. However, if you are suffering from cold sores; then chances are your immune system is unable to fight off certain virus.
Stress: They may also be brought on by stress – for example, many students get them during exams. This has been one of the leading factors for almost any type of illnesses or diseases that our bodies acquire.
Allergies: They may be associated with an increased risk for canker sores. Many of us are unaware that some of the foods or medications may be triggers for canker sores or act as nutrients for the Streptococcus bacteria.
Hereditary: If canker sores run in your family then you may be more prone to getting infected with the virus.
Sun: Believe it or not the sun has been known to cause these things to pop up as well.
Toothpastes: Certain brands that contain sodium lauryl sulfate have been responsible for this condition as well.
Menstrual period: Canker sores often occur near the time of a menstrual period.

Lack of cyanocobalamin (vitamin B12), folic acid, or iron.
People with canker sores often have small injuries from dental injections and toothbrushes in the lining of the mouth.
