When gingivitis results in some blistering, the patient can frequently rinse their mouth. After rinsing, it is appropriate to spray some oral inflammation spray on the gums locally, which can help in anti-inflammatory treatment and repair the blisters. Additionally, the patient can take some anti-inflammatory medications orally to treat the symptoms of gingivitis, which can effectively alleviate the inflammation. Regarding diet, the patient should also pay attention to eating light, avoiding spicy and irritating foods, adjust their lifestyle and drink more water. Locally, it's important to maintain oral hygiene, rinse mouth promptly after meals to remove food residues and prevent bacterial infection, and develop correct brushing habits. Moreover, it is suggested that patients should have their teeth cleaned regularly every year to prevent recurrent attacks of gingivitis.
