Swollen gums inside the incisors may be the result of chronic periapical inflammation of the incisors. Inflammation of the periapical area causes pus and inflammatory exudate to appear in the periapical area, and a pus-draining sinus tract at the corresponding gums, which can cause redness, swelling, and pus growth in the gums. For teeth with chronic apical periodontitis, a root canal is clinically performed on the tooth. Swollen gums on incisors may also be suffering from chronic periodontitis, which can lead to congestion, redness and swelling of the periodontal tissues, and even periodontal abscesses, which can lead to swollen gums. In terms of treatment, in the acute stage of periodontal abscess, you need to do periodontal abscess rinsing and medication, and after the acute stage, you need to do ultrasonic cleaning and periodontal scraping treatment. Swollen incisor gums can also be caused by food impaction, or eating spicy and irritating food, or hot food, resulting in inflammation of the gum papillae caused by gum redness and swelling. If the gums on the inside of the incisors are swollen and painful with ulceration of the mucous membranes, it means that the mucous membranes are suffering from mouth ulcers.
