Gingivitis, or inflammation of the gums, is a long-term formation of plaque, or a thin layer of soft, sticky and colorless bacteria, on the teeth and gums. The gums are significant due to edema or fibrosis, with a red or dark red color, elevated temperature in the gingival sulcus, and irritation that tends to bleed. Signs and symptoms are confined to the gingival tissue. The amount of gingival sulcus fluid is increased and the temperature is elevated. Symptoms: 1. Typical signs and symptoms of gingivitis include redness and swelling as well as bleeding from soft gums caused by brushing. 2, Another sign of gingivitis is gum recession or separation from your teeth, which makes your teeth look like they have been stretched. 3. Gum disease creates a groove between the teeth and gums where plaque and food debris converge. Some people may have a recurring unpleasant odor or unpleasant taste sensation in their mouth even if the condition does not escalate. Diagnosis: 1. The important difference between gingivitis and early periodontitis is the presence or absence of attachment loss and alveolar bone resorption. 2, chronic gingivitis due to inflammatory swelling of the gingiva, the depth of the gingival sulcus can be more than 3mm, but there is no loss of connective tissue attachment, the bottom of its gingival sulcus is still located at the enamel bone boundary or its crown side, and no alveolar bone resorption can be seen in the X-ray. 3, clinical should carefully check the presence of attachment loss on the adjacent surfaces of the molars and incisors, can take jaw wing film to observe whether there is alveolar crest resorption.
