The oral mucosa has not been well for two years. It doesn't hurt or itch. If you eat stimulating food, you will get sick
I don't know whether I have bad habits such as chewing betel nut at ordinary times. From the picture, it can't be diagnosed as leukoplakia, lichen planus and erythema of oral mucosa, nor can it be ruled out as oral mucosal fibrosis. Avoid the stimulation of hot, dry, hard and spicy food and maintain oral hygiene. You can gargle with Kangfuxin solution. It is recommended to see a doctor in the stomatology department of a regular hospital.
There is a possibility of fibrosis in the oral mucosa. You can go to the oral mucosa Department of the hospital to check the local situation. If necessary, you can carry out local histopathology, avoid eating spicy and irritating food, gargle with some Kangfuxin mouthwash, maintain oral hygiene, and eat more fresh vegetables and fruits.
This may be oral ulcer. If it is oral ulcer, you can treat it with watermelon cream spray and oral ulcer powder. You must pay attention to oral health protection at ordinary times. You can gargle with Kangfuxin solution, pay attention to diet, eat more vegetables and fruits rich in vitamins and eat less irritating food as much as possible.
