1, improve the autoimmune ability.
First of all, it should be noted that the disease of oral ulcer is directly related to our own immune function, that is to say, if we can improve our immune function, it will be better to prevent oral ulcer, so I suggest that everyone can improve their immune ability through exercise.
2, pay attention to oral cleaning
Keeping your mouth clean often can also help us prevent the disease of oral ulcer, so I suggest you keep your mouth clean as much as possible. Besides brushing your teeth once every morning and evening, I suggest that you also develop the good habit of gargling.
Step 3 prevent getting angry
Many times, when our stomach fire is strong, it is easy to cause our oral mucosa to rupture and slowly develop into oral ulcers. So in special seasons, we should pay attention to prevent ourselves from getting angry. Usually, you should eat more fruits and drink more water to keep your body adequately supplied with water.
