Common Causes And Risk Factors For Canker Sores

Lack Of Nutrients In Diet

Diet and nutrients play a key role in preventing many skin and mouth diseases, including canker sores. One vitamin deficiency that often causes ulcers, especially in children, is a B-12 deficiency. Growing kids require even more B-12 than adults and, unfortunately, tend to avoid the fruits and vegetables that have it in abundance, making a B-12 deficiency quite common in children and teens, but adding a B-12 supplement or applying the contents of B-12 vitamin capsules directly to the sores can help treat and prevent the issue.

Other nutrient deficiencies have also been linked to canker sores. A lack of nutrients, particularly folic acid, iron, and zinc, can cause canker sores or make them worse. A lack of calcium may not directly cause canker sores, but it has been shown to make them worse. For these nutrient deficiencies, making simple diet changes to foods rich in all four can create the biggest difference.
