Canker Sores: What They Are and How to Deal with Them

Canker sores are a common, albeit annoying, mouth issue that many people experience at some point. They’re small, painful ulcers that appear inside the mouth, and while they’re not usually serious, they can be quite bothersome. Here’s a friendly guide to understanding canker sores and what you can do to ease the discomfort.

What Are Canker Sores?

Canker sores, also known as aphthous ulcers, are small, shallow sores that develop on the soft tissues inside your mouth, such as the inside of your cheeks, lips, or under your tongue. They often appear as white or grayish ulcers with a red halo around the edges. Canker sores can make eating, drinking, and speaking uncomfortable.

What Causes Canker Sores?

The exact cause of canker sores isn’t always clear, but several factors may contribute:
  • Stress: Emotional stress and anxiety can trigger canker sores in some people.
  • Dietary Triggers: Certain foods, like citrus fruits, tomatoes, and spicy dishes, can irritate the mouth and lead to canker sores.
  • Nutritional Deficiencies: Lack of essential nutrients, such as vitamin B12, folic acid, or iron, may increase the risk of developing sores.
  • Injury: Accidentally biting the inside of your cheek or brushing too hard can create small injuries that turn into canker sores.
  • Hormonal Changes: Hormonal shifts, particularly during menstruation, can sometimes trigger outbreaks.

How to Relieve the Pain

  • Over-the-Counter Remedies: Look for topical treatments or gels designed to numb the area and reduce discomfort.
  • Saltwater Rinse: Rinsing your mouth with a saltwater solution can help soothe the sore and promote healing.
  • Avoid Irritating Foods: Steer clear of spicy, acidic, or abrasive foods that can aggravate the sore.
  • Maintain Good Oral Hygiene: Brush gently with a soft-bristled toothbrush and avoid using toothpaste with sodium lauryl sulfate, which can irritate the mouth.

When to See a Dentist

If canker sores are particularly large, persistent, or recurrent, or if you experience severe pain or difficulty swallowing, consult your dentist. They can help identify any underlying issues and recommend appropriate treatments.

Final Thoughts

Canker sores are a common annoyance but are usually not a cause for concern. With some self-care and a bit of patience, they typically heal on their own within one to two weeks. By managing triggers and using soothing remedies, you can make the experience a bit more bearable and get back to enjoying your favorite foods and activities.
