There's no known way to avoid canker sores, although you can try the following prevention tips:

  • Be gentle when brushing your teeth, and use a mild toothpaste.
  • Avoid citrus fruits and drinks (tomatoes, pineapples, grapefruit, and oranges).
  • Learn to handle your stress, as emotional stress may trigger mouth ulcers.
