How long will oral ulcer get better?
Oral ulcer is a superficial ulcer occurring on the oral mucosa, which can be round or oval in size from rice grains to soybeans. The ulcer surface is concave and congested around, which can cause pain due to irritating food. Generally, it can heal itself in one to two weeks.

Patients should pay attention to:

1. Develop good oral hygiene habits to avoid damaging the oral mucosa and avoiding spicy, fried food and local irritation.

2. Keep a good mood, be optimistic and cheerful, and avoid being nervous and anxious.

3. Ensure adequate sleep time and avoid excessive fatigue.

4. Pay attention to the regularity of life and nutritional balance, and develop certain defecation habits to prevent constipation.
