How Can I Prevent Canker Sores?

Prevention is not foolproof, but there are some things you can do to help ward off canker sores:

  • Brush your teeth with disinfecting baking soda.
  • Eat 4 tablespoons of live-culture yogurt a day; it contains bacteria that can keep your system healthy.
  • Avoid foods that are spicy, salty, or acidic.
  • Take vitamin and mineral supplements C, B complex, folic acid, iron, and zinc.
