Canker sores, also known as aphthous ulcers, can cause significant discomfort and pain. While they usually heal on their own within a week or two, certain foods can worsen the irritation and delay healing. Knowing which foods to avoid can help manage symptoms and promote faster recovery.

Foods to Steer Clear Of

When dealing with a canker sore, it’s best to avoid foods that are spicy, acidic, or rough in texture. These can irritate the sore and cause increased pain or inflammation.

Spicy Foods

Spices like chili peppers, hot sauces, and curry powders contain capsaicin, which can intensify the burning sensation and irritate the sore further.

Acidic Foods and Drinks

  • Citrus fruits such as oranges, lemons, and grapefruits
  • Tomatoes and tomato-based products
  • Vinegar and pickled foods
  • Fruit juices, especially citrus juices

These acidic items can cause a stinging sensation and may prolong healing time.

Rough or Crunchy Foods

  • Chips and pretzels
  • Toast and crusty bread
  • Raw vegetables like carrots and celery

Hard, abrasive foods can scratch or irritate the sore, making it more painful and delaying recovery.

Additional Tips for Relief

Besides avoiding certain foods, consider eating soft, bland foods like yogurt, mashed potatoes, and smoothies. Maintaining good oral hygiene and avoiding irritants like tobacco and alcohol can also help speed up healing.
