Home Remedies for Mouth Ulcers: Effective and Natural Solutions for Fast Relief
Mouth ulcers, also known as canker sores, are painful lesions that develop on the gums, inside the lips, cheeks, or under the tongue. While they are generally harmless and tend to heal on their own, their discomfort can interfere with eating, speaking, and overall oral hygiene. Fortunately, several home remedies and nutritional adjustments can expedite healing and lessen pain, allowing sufferers to manage their symptoms safely at home and reduce the likelihood of recurrence.

Understanding Mouth Ulcers
Mouth ulcers, medically termed as aphthous ulcers or canker sores, typically appear as small, round or oval sores with a white or yellowish center and a red border. Most ulcers are benign but can be extremely painful and may signal underlying health issues if they persist or recur frequently.
- Common Causes: Minor injury, stress, hormonal changes, allergies, vitamin deficiencies, and consumption of spicy or acidic foods.
- Symptoms: Painful sore in the mouth, discomfort during eating or talking, burning or tingling before the ulcer appears.
- Duration: Most mouth ulcers heal within 7–14 days without medical treatment.
Common and Effective Home Remedies
Over-the-counter solutions exist, but home remedies are often just as effective, accessible, and gentle on oral tissues. Below is a detailed overview of the most popular and scientifically-backed options you can safely try at home.
Saltwater Rinse
One of the oldest and simplest remedies, saltwater rinse helps disinfect the sore, reduces inflammation, and may speed healing. Mix one teaspoon of salt in a cup of lukewarm water, rinse for 15-30 seconds, then spit it out. Use twice daily for optimal results.
Benefits: Disinfection, alleviation of pain, and faster healing.
Note: May sting initially but is highly effective.
Baking Soda Paste
Baking soda (sodium bicarbonate) neutralizes acids and reduces pain from canker sores. Mix baking soda with water to form a thick paste, apply to the ulcer, and rinse after a few minutes.
Benefits: Reduces inflammation, neutralizes acidity.
Frequency: Once or twice daily.
Honey Application
Honey is a natural antibacterial agent that creates a protective coating and encourages tissue repair. Dab a small amount of honey directly on the ulcer three to four times a day.
Benefits: Soothing, antimicrobial, accelerates healing.
Coconut Oil
Coconut oil’s antimicrobial and anti-inflammatory properties can reduce pain and keep ulcers moisturized. Apply a few drops to the affected area several times daily.
Benefits: Pain relief, infection prevention, reduced inflammation.
Ice Cubes
Suck on ice chips or hold an ice cube against the sore to numb the area and reduce swelling. Useful for immediate though temporary pain relief.
Benefits: Numbs pain, decreases swelling.
Yogurt
Plain yogurt with live cultures helps restore healthy bacteria in the mouth, especially useful if ulcers are caused by an imbalance of oral flora.
Benefits: Restores microbial balance, supports oral and gut health.
Baking Soda Solution
For another approach, mix baking soda in water and swish as a rinse. This helps neutralize mouth acidity and alleviate discomfort.
Milk of Magnesia
Milk of magnesia neutralizes acidity and soothes irritation. Dab directly onto the ulcer two or three times daily.
Alum Powder Paste
Alum powder acts as an astringent. Make a paste with a few drops of water, apply to the ulcer, and rinse thoroughly after it has dried.
Benefits: Dries out the sore and speeds healing.
Hydrogen Peroxide (3%)
Use a diluted hydrogen peroxide rinse (one part peroxide to four parts water) as a mouthwash to disinfect and support healing. Do not swallow.
Herbal and Natural Supplements
- Chamomile Tea: Chamomile contains anti-inflammatory compounds (azulene, levomenol). Use as a rinse or compress by steeping a chamomile tea bag, cooling, and applying to the sore.
- Licorice Root: Its anti-inflammatory effects support mouth healing when used as a mouth rinse.
- Turmeric Paste: Turmeric powder, mixed with water, forms a paste that reduces pain and inflammation when applied directly to the ulcer twice daily.
- Clove Oil: Clove contains eugenol, which is both analgesic and antimicrobial. Dab a tiny amount on the sore for pain relief.
- Echinacea: Boosts immune response; use as a mouth rinse to aid recovery.
Apple Cider Vinegar
Dilute one teaspoon of apple cider vinegar in a half cup of lukewarm water, swish, and spit out. Its antibacterial properties may help kill microbes responsible for ulcers. Avoid overuse, as high acidity can irritate oral tissues.
Dietary Tips for Faster Healing
Diet has a direct impact on the occurrence and healing of mouth ulcers. Follow these key recommendations to promote comfort and speed recovery:
- Choose soft, bland foods (bananas, oatmeal, boiled vegetables) to reduce irritation.
- Avoid foods with sharp edges (toast, chips) and acidity (citrus fruits, tomatoes).
- Eliminate or minimize spicy foods to prevent aggravation.
- Stay hydrated with water and herbal teas.
- Increase intake of foods rich in vitamins B12, iron, and folic acid (eggs, leafy greens, nuts, legumes).
- Consider probiotic-rich foods (yogurt, kefir) to support healthy oral flora.
Sample Table: Foods to Eat & Avoid with Mouth Ulcers
Foods to Eat | Foods to Avoid |
---|---|
Bananas | Citrus fruits |
Boiled vegetables | Spicy foods |
Oatmeal & rice | Sharp/crunchy snacks |
Yogurt (plain, unsweetened) | Tomatoes |
Eggs, well-cooked meats | Acidic juices |
Oral Hygiene Best Practices
Consistent oral hygiene is essential to prevent mouth ulcers and promote healing:
- Brush gently with a soft-bristled toothbrush to avoid trauma.
- Use alcohol-free mouthwash to keep the mouth clean without irritating tissue.
- Clean your mouth after meals to reduce bacterial buildup.
- Avoid harsh toothpaste containing sodium lauryl sulfate, which can increase ulcer risk.
- Replace your toothbrush regularly to prevent bacterial transfer.
When to See a Dentist or Doctor
Most mouth ulcers resolve within two weeks. Seek professional help if:
- The sore lasts longer than 3 weeks or keeps returning.
- Ulcers are unusually large, or you develop high fever or severe pain.
- Difficulty in swallowing or speaking.
- You suspect underlying health issues (immune system problems, nutritional deficiencies, allergies).
Recurrent mouth ulcers may require medical investigation for food allergies, vitamin or mineral deficiencies, or rare conditions like Behçet’s disease.
