Can canker sores be prevented?

ANSWER

Although there is no cure for canker sores -- and they often recur -- you may be able to reduce their frequency by:

1. Avoiding foods that irritate your mouth, including citrus fruits, acidic vegetables, and spicy foods

2. Avoiding irritation from gum chewing

3. Brushing with a soft-bristled brush after meals and flossing daily, which will keep your mouth free of foods that might trigger a sore
