Mouth ulcers, also known as canker sores, are small but painful lesions that develop in your mouth or at the base of your gums. While they're usually harmless and go away on their own within a week or two, they can make eating, drinking, and even talking uncomfortable. Fortunately, there are several ways to speed up healing and reduce discomfort.

What Causes Mouth Ulcers?

Before treating them, it’s helpful to understand what might be causing them. Common triggers include:

Stress or lack of sleep
Minor mouth injuries (like biting your cheek or irritation from braces)
Certain foods (like citrus, spicy food, or acidic items)
Nutritional deficiencies (especially B12, iron, or folic acid)
Hormonal changes
Underlying health conditions (such as celiac or Crohn’s disease)

Effective Home Remedies

1. Salt Water Rinse

Mix a teaspoon of salt in a glass of warm water and rinse your mouth for 30 seconds. It may sting, but salt helps dry out the ulcer and speed up healing.

2. Baking Soda Paste

Make a paste with baking soda and a few drops of water. Apply it directly to the sore to neutralize acid and reduce inflammation.

3. Honey

Dab a small amount of honey directly on the ulcer 3-4 times a day. Its antibacterial and anti-inflammatory properties can help soothe and heal.

4. Coconut Oil

Coconut oil has antimicrobial properties and acts as a barrier to help reduce irritation and pain. Apply it gently using a clean finger or cotton swab.
