Canker sores, or also scientifically known as aphthous ulcers, can not only be annoying but also painful. They are a type of mouth ulcer that can interfere with usual activities such as eating and drinking. Salty foods are the most common thing to irritate a canker core.
Immune System
If the immune system is weak, canker sores are more likely to occur. This usually happens when a person's immune system identifies chemical molecules that it doesn't recognize.
Mouth Trauma
Mouth trauma such as a sharp potato chip, when someone bites their own cheek, or a sharp tooth edge can cause a canker core. 38 percent of people who have canker cores usually get it from one of these forms of a mouth trauma.
Stress
Many people who have suffered from a canker sore have had some form of emotional or physical stress. Stress can harm the health in a variety of ways.
Diet
A vitamin deficiency can cause a canker sore. Such deficiencies include vitamins B1, B2, B6, B12, and Vitamin C.
Allergies
Allergies to certain foods have been known to cause canker sores. Foods to stay away from if you have a history with canker sores include cereal grains, fruits and vegetables, dairy, additives, and other foods such as nuts and chocolate.
