10 Causes Of Canker Sores
Reviewed: Dr. Gromatzky
Cause #5: Food Allergies
Food allergies may cause canker sores. It is not clear which specific foods are responsible for the flare ups. However, as with other sensitivities, food allergies can lead to inflammation on various parts of the body. The inflamed part of the body may break out into sores. When this happens in the mouth, it can cause oral sores.
Consumption of foods that you are allergic to can lead to recurrent canker sores. Therefore, if you are susceptible to developing mouth sores, and notice that some foods could be causing flare ups, avoid them as much as possible. This may reduce the frequency of the mouth sores.
