Common Causes And Risk Factors For Canker Sores

Food Sensitivities

Some fruits and vegetables may or may not cause canker sores, but for individuals who already have them or suffer from them frequently, highly acidic citrus fruits, spicy foods, coffee, and chocolate can trigger or make the sores worse. The open lesion inside of a canker sore can also leave your mouth extremely sensitive to any acidic foods you eat. Foods such as strawberries, tomatoes, and apples should also be avoided when you have canker sores. Some auto-immune conditions, such as celiac disease, can cause canker sores too.
