Causes Of Canker Sores (Cold Sores)

The exact cause of canker sores remains unclear, although researchers suspect that several factors contribute to the outbreak, although a single individual. These factors include:

Minor injuries to the mouth of dentures, overzealous brushing, sports injuries, spicy foods or acidic, or accidental cheek bite

Food sensitivities, especially for chocolate, coffee, strawberries, eggs, nuts, cheese and highly acidic foods like pineapple

Food Allergies

A diet deficient in vitamin B-12, zinc, folate (folic acid) and iron

An allergic reaction to certain bacteria in the mouth

Helicobacter pylori, the same bacteria that causes peptic ulcers

Celiac disease, a severe intestinal disease caused by sensitivity to gluten, a protein found in most grains

Inflammatory bowel diseases like Crohn's disease and ulcerative colitis

Behçet's Disease, a rare disease that causes inflammation in the body including the mouth

A faulty immune system that attacks healthy cells in the mouth instead of pathogens such as viruses and bacteria

HIV / AIDS that suppress the immune system

Hormonal changes during menstruation

Emotional stress

Toothpastes and mouth rinses containing sodium lauryl

Unlike cold sores, canker sores are not associated with herpes viral infections.
