How should pregnant women deal with mouth ulcers?
Generally, when pregnant women deal with mouth ulcers, they should focus on safety and effectiveness to avoid adverse effects on the fetus. Management options include dietary adjustments, maintaining oral hygiene, applying cold compresses, using medicated mouthwashes, and topical medications. The details are as follows:

1. Dietary Adjustments
Consume more foods rich in vitamins B and C, such as carrots, kiwifruit, and oranges, which help repair oral mucosa. Reduce intake of spicy, cold, and hard foods that may irritate the mucosa and worsen ulcers.
2. Maintain Oral Hygiene
Brush teeth with a soft-bristled toothbrush in the morning and evening to keep the mouth clean and reduce bacterial growth. Rinse with salt water or mouthwash after meals to remove food debris and bacteria. Use dental floss to clean between teeth and prevent secondary infections.
3. Cold Compress
Wrap ice cubes in a clean cloth or towel and apply to the ulcerated area for about 10–15 minutes each time, multiple times daily. Cold compresses can reduce local nerve sensitivity, alleviating pain and discomfort.
4. Medicated Mouthwash
Use safe solutions such as normal saline. Rinse for about 2–3 minutes each time, multiple times daily. These solutions have antibacterial and anti-inflammatory effects, helping to reduce inflammation and pain associated with mouth ulcers.
5. Topical Medication
Under a doctor's guidance, use anti-inflammatory and antibacterial medications such as oral ulcer powder, pearl yellow powder, or watermelon frost. Apply the medication gently to the ulcerated area multiple times daily, but avoid self-medicating without medical advice.
When treating mouth ulcers, pregnant women should prioritize methods that are safe for both the mother and the fetus and follow medical advice during treatment. Maintaining good oral hygiene and healthy dietary habits can also help prevent mouth ulcers.
