Here are a few dietary recommendations for those with canker sores:
  • Stay away from spicy foods.
  • Avoid foods that are too hot.
  • Avoid foods with crusts or sharp edges, such as crackers and chips.
  • Avoid foods that are highly acidic, such as tomatoes and citrus juices.
  • Stay away from foods high in arginine, an amino acid found in chocolate and nuts.
  • Eat foods high in lysine, an amino acid. Lysine is found in cheese, eggs, fish, red meat, lima beans, potatoes, and soy products.
Usually canker sores heal within a week or two. However, if you have a large canker sore, call your doctor or dentist. There are some oral medications that can help dry up the mouth ulcer.
