According to what you said, if you have wisdom teeth, it is generally best to eat less spicy food, such as pepper and carbonated drinks (coke, sprite, etc. ) and pork! Because pericoronitis of wisdom teeth will occur when wisdom teeth grow, eating spicy and stimulating food will be aggravated! The general principle is not to eat too much, eat less fried food, eat less cold food, eat less meals and avoid strenuous exercise after meals. Specifically, I suggest you drink porridge, yam, coix seed and millet porridge, all of which are good. Then we must pay attention to maintaining good oral hygiene! Rinse your mouth immediately after eating! If gingivitis is caused by Zhang Zhiyi, you can take roxithromycin dispersible tablets to treat it. If it is often inflamed, it is necessary to check whether Zhang's position is not good and pull it out if necessary.
