What Are The Causes Of Mouth Ulcer? 12 Common Triggers

Genetics

Mouth ulcers are considered hereditary. This means that if a parent has experienced recurring mouth ulcers caused by food sensitivity, uncontrollable biting, or allergies, the offsprings are highly likely to develop mouth ulcers as well.

Around 20 percent of people around the globe have experienced mouth ulcers. But for some who frequently experience canker sores, it is more likely due to genetics. People who inherited gene variants of pro-inflammatory responses or those gifted with cells that fight back bacteria through inflammation are more prone than those who inherited non-pro-inflammatory responses. This is due to inflamed blood vessels throughout the body, including the cheeks and gums. These pro-inflammatory genes include interleukins, tumor necros factor-a, E-selectin, and matrix metalloproteinases. 

Mouth ulcers due to genetics are hard to cure. But maintaining dental hygiene and a healthy diet will significantly help prevent them.
