Canker Sores: Small Size, Big Pain


If you’ve got a canker sore, be sure to brush the area gently.

They’re small and unsightly white or yellow lesions that can erupt anywhere in the mouth. Canker sores, which are usually round or oval, can be a big pain, literally, for those who frequently suffer from them. Minor canker sores usually go away in a week or two, but bigger ones are often extremely painful and can take as long as six weeks to heal.

Common Triggers

Stress: Often implicated in a variety of health issues, stress also plays a role in the development of canker sores. Limiting stress can help keep your mouth free of these bothersome blisters.

Certain foods: Acidic and spicy foods, such as citrus fruits and chili peppers, can prompt the development of canker sores. It’s also been discovered that gluten, the protein found in wheat, can play a role in canker sore growth. Consider keeping a food diary to see if the development of canker sores coincides with eating particular foods.

Vitamin deficiencies: According to various studies, a deficiency of folic acid, zinc or iron in the body can initiate the development of canker sores. One study revealed that a nightly dose of vitamin B12 may be an effective and natural therapy for canker sores. Eating a nutrient-dense, well-balanced diet is one of the best ways to ensure you’re getting all the vitamins and minerals your body needs.

Mouth Care

If you have one or more canker sores, it’s important to brush gently, using a soft-bristled toothbrush. Applying too much pressure could irritate an existing sore or cause a new lesion to develop. Over-the-counter canker sore remedies, including gels, liquids and patches, can be applied to the canker sore to temporarily take the pain away.
