1. What is the reason for the swelling and pain on the left side of the oral cavity?

Swelling and pain on the left side of the mouth may be caused by swollen gums. The main causes of swollen and painful gums include gingival abscess, periodontal abscess, wisdom tooth pericoronitis or apical periodontitis, etc. The most common disease is caused by periodontal abscess, and wisdom tooth pericoronitis is more common in young people. Patients often have chronic inflammation of the gums or periodontal tissues. When the body's resistance is reduced, the weather is dry, they eat spicy food, or suffer from systemic diseases such as diabetes, the original chronic inflammation will cause an acute attack and symptoms of swollen and painful gums will appear.

You can use salt water, normal saline, or medicated mouthwash to reduce oral bacteria and prevent secondary infection caused by food residues. This is an important aspect of preventing oral ulcers.

2. To prevent oral ulcers, you should reduce irritation and friction to the oral mucosa, eat less irritating condiments such as chili, vinegar, ginger, onion, curry, etc.; eat less fried chicken legs, fried steak or other foods that are too rough and hard.

3. Pay attention to nutritional balance, eat more easily digestible foods rich in B vitamins, do not be picky eaters, and eat more fresh vegetables and fruits, which are beneficial for preventing oral ulcers. Try to eat less bamboo shoots (winter bamboo shoots, hairy bamboo shoots, dried bamboo shoots), pickled products (salted fish, bacon, pickled vegetables), persimmons and crabs, etc., which can easily aggravate oral ulcers.

4. Develop good living habits, ensure adequate sleep, avoid overwork; cultivate the ability of self-psychological regulation, because emotional factors not only affect the nervous system, but also can lead to digestive system disorders and nutritional disorders, bad mood, and mental tension.
