Mouth Ulcers and Oral Thrush in Children: Natural Remedies to Soothe and Heal

Mouth ulcers and oral thrush are not limited to adults — children can also develop them, especially during teething, when experiencing food allergies, nutrient deficiencies, or yeast infections.

While oral thrush often clears up on its own, natural treatments can help relieve pain and speed recovery. In some cases, medical treatment may still be necessary to prevent complications and ensure complete healing.

Before using medications, parents can try the following safe, natural home remedies recommended by Healthline.

1. Salt Water Rinse

Research shows that rinsing with salt water can reduce inflammation, relieve pain, and eliminate bacteria and fungi in the mouth.

It can also speed up healing of oral ulcers in children.

To prepare:

Dissolve 1 teaspoon of salt in a cup of warm water.
Have your child rinse and spit out the solution after a few seconds.
Repeat this 2–3 times a day for best results.

2. Tea Tree Oil

Tea tree oil is known for its strong antibacterial and antifungal properties, making it effective against oral thrush.

Mix 2 drops of tea tree oil with half a cup of water.
Apply gently to the ulcer using a clean cotton swab.
Always use diluted oil and consult your pediatrician before use.

3. Virgin Coconut Oil

Virgin coconut oil is soothing and helps calm oral ulcers in children.

Make sure to use pure, additive-free virgin coconut oil.
Apply a thin layer gently over the sore area several times a day.

4. Probiotics for Oral Health

Probiotics help restore microbial balance in the mouth, suppressing harmful bacteria and promoting healing.

They not only relieve mouth ulcers but also prevent tooth decay and gum inflammation.

You can find probiotics in plain, unsweetened yogurt — always choose low-sugar options and avoid preservatives before giving them to your child.

5. Cold Compress

A cold compress can quickly numb pain and reduce swelling caused by mouth ulcers.

Cold temperatures temporarily soothe nerves, ease inflammation, and minimize the burning sensation.

You can use ice packs or chilled spoons on the affected area for short intervals.

6. Oral Hygiene

Maintaining good oral hygiene is essential for prevention and recovery.

Teach your child to brush twice daily using a soft-bristled toothbrush to avoid irritating the ulcers.
Encourage gentle brushing and regular flossing.
A saltwater or antibacterial mouthwash can also help reduce discomfort and infection.

7. Honey (Especially Manuka Honey)

Studies suggest that honey can reduce pain, redness, and ulcer size due to its antibacterial and anti-inflammatory properties.

Apply Manuka honey directly to the ulcer 4 times daily for best results.
⚠️ Important: Do not give honey to children under one year old, as it may contain Clostridium botulinum spores that can cause infant botulism.

8. Black Tea Bags

After brewing black tea, don’t throw away the tea bags — they can be a great natural remedy for mouth ulcers.

Place a used, cooled tea bag on the affected area for a few minutes.
Black tea contains tannins, compounds that help reduce pain and inflammation (they’re also found in many common pain relievers).

9. Nutrition and Diet

Children with mouth ulcers may refuse to eat or drink due to discomfort.

To meet their nutritional needs:

Offer soft, mild foods such as porridge or purees instead of rice or spicy meals.
Give milk or diluted fruit juice for hydration and nutrients.
Ensure adequate vitamins and minerals — especially zinc, iron, vitamin B, and vitamin C.
Cold treats like ice cream can provide relief and nutrition at the same time.
Keep your child well hydrated to prevent dehydration.

Final Note

Oral thrush and mouth ulcers in children are usually not serious, but they can cause discomfort and affect appetite.

If symptoms persist, worsen, or are accompanied by fever or difficulty swallowing, consult a pediatrician for proper diagnosis and treatment.
