In this article, we’ll explore quick relief tips for soothing mouth ulcers in toddlers.

What causes mouth ulcers in toddlers?

Mouth ulcers, known as aphthous ulcers, are small, painful sores that can appear inside your toddler’s mouth. There are several possible causes of mouth ulcers in toddlers, including:

  • Injury from accidentally biting the inside of the mouth or chewing on hard items
  • Viral infections such as hand, foot, and mouth disease
  • Bacterial infections
  • Fungal infections
  • Allergic reactions to certain foods or medications
  • Emotional stress

How to soothe mouth ulcers in toddlers

1. Offer cold foods and liquids

Cold foods and liquids can help to numb the pain caused by mouth ulcers. Offer your toddler cold yogurts, popsicles, and smoothies.

2. Avoid acidic foods and drinks

Acidic foods and drinks can irritate mouth ulcers and make the pain worse. Avoid giving your toddler citrus fruits, tomatoes, and acidic juices.

3. Use a topical numbing gel

You can purchase a topical numbing gel over-the-counter at your local pharmacy. Apply the gel to the mouth ulcer to provide pain relief.

4. Rinse with saltwater

Warm saltwater can help to reduce the inflammation and pain caused by mouth ulcers. Mix a small amount of salt with warm water and have your toddler swish it around their mouth for a few minutes.

5. Apply honey

Honey has antibacterial and anti-inflammatory properties, which can help to soothe and heal mouth ulcers. Apply a small amount of honey directly to the ulcer.

6. Use a soft-bristled toothbrush

Mouth ulcers can be painful, especially when brushing teeth. Use a soft-bristled toothbrush and brush gently to avoid irritating the ulcers further.

7. Give pain relief medication

If your toddler is experiencing severe pain, over-the-counter pain relief medication can help. Consult with your healthcare provider to determine the appropriate medication and dosage for your child.

1. Maintain good oral hygiene

Encourage your toddler to brush their teeth twice a day and floss daily to prevent the buildup of bacteria in the mouth.

Keep track of any foods that may trigger mouth ulcers in your child, such as spicy or acidic foods. Limit or avoid these foods as necessary.
