The main symptoms of gum inflammation are bleeding gums, deepening color, rounded shape and soft texture. 1. Bleeding gums: When gums are inflamed, patients often bleed when brushing or biting hard objects. Doctors will also bleed when the gums are gently probed with a periodontal probe. 2. Gum color: Normal gums are pink, but when the gums are inflamed, the free gums and gingival papilla become bright red or dark red. 3. Gum shape: When the gums are inflamed, the margins of the gums become thicker and no longer adhere to the surface of the teeth, and the gingival papillae become rounded and enlarged to cover the surface of the teeth. 4. Gum texture: When the gums are inflamed, the gums become soft and fragile, lack of elasticity, and do not adhere to the tooth surface. In addition, inflammation of the gums is occasionally accompanied by localized swelling of the gums, pain, bad breath and other symptoms. Related symptoms should be promptly consulted and treated under the guidance of a doctor.
