How to Treat Mouth Ulcers with Home Remedies

Mouth ulcers (also called canker sores) are painful sores that appear inside the mouth, on the tongue, gums, or inner cheeks. They can make eating, drinking, and talking uncomfortable. While most ulcers heal on their own within 7–14 days, the pain can be significant. Home remedies can reduce discomfort and support faster healing.

This guide shares the most effective and safe home remedies to treat mouth ulcers using ingredients commonly available in Indian homes.

Common Causes of Mouth Ulcers

• Accidental biting or injury from sharp teeth or food
• Stress and lack of sleep
• Nutritional deficiencies (especially B vitamins, iron, and folate)
• Spicy, acidic, or very hot foods
• Hormonal changes
• Certain toothpastes containing sodium lauryl sulfate
• Underlying digestive issues or weakened immunity

Best Home Remedies for Mouth Ulcers

1. Curd or Yogurt

Plain curd contains beneficial bacteria that support oral healing and soothe the affected area. Eating a small bowl of plain curd or applying a little on the ulcer can provide relief.

2. Honey

Honey has natural antibacterial and wound-healing properties. Apply a small amount of pure honey directly on the ulcer a few times a day.

3. Coconut Water

Drinking tender coconut water helps cool the system and provides gentle hydration. It is especially useful when ulcers are linked to excess body heat or acidity.

4. Tulsi Leaves

Chew a few fresh tulsi leaves or make a mild tulsi rinse. Tulsi has traditional use for oral health and mild antimicrobial action.

5. Alum (Phitkari) – Use Carefully

A very small pinch of alum mixed with water can be used as a mild rinse for some people. Do not apply dry alum directly as it can sting strongly. Use only occasionally and in high dilution.

6. Pomegranate Peel or Juice

Pomegranate has astringent properties. Some people use a mild decoction of the peel as a rinse, or simply eat fresh pomegranate seeds.

7. Cold Milk or Ice

Sipping cold milk or gently applying ice (wrapped) can temporarily numb the pain and reduce inflammation.

8. Avoid Irritants

While treating ulcers, strictly avoid spicy food, citrus fruits, very salty snacks, and hard or crunchy foods that can aggravate the sores.

Supportive Care for Faster Healing

• Maintain good oral hygiene with a soft-bristle brush
• Stay hydrated
• Manage stress through adequate sleep and relaxation
• Eat a balanced diet rich in vegetables, dals, and whole foods to correct possible deficiencies
• Consider a B-complex supplement if ulcers are recurrent (after consulting a doctor)

When to See a Doctor

Consult a doctor if:

• Ulcers last longer than two weeks
• They are unusually large or extremely painful
• You have frequent recurrent ulcers
• There is fever or difficulty swallowing
