Gum enlargement is a sign of gum inflammation and possibly periodontal inflammation, which are typical symptoms of periodontal disease. Gingival hyperplasia is usually present in the mouth as a symptom of gingivitis and periodontitis, both of which are the most common periodontal diseases. Periodontal disease is a disease of the soft tissues surrounding the teeth, formed by plaque acting on the teeth and irritating the periodontal tissues, the initiating factor of periodontal disease is plaque. The main symptoms of gingivitis include red and swollen gums, bleeding gums, gum recession, gum hyperplasia, rounded gum papillae, dark red color of gums, etc. If the inflammation of the gums is not controlled, the inflammation will continue to destroy the periodontal tissues and form periodontal pockets, resulting in loss of attachment, as well as the resorption of alveolar bone, and slowly the teeth will loosen or even fall out, which is the development of periodontal inflammation. Gingivitis and periodontitis must be diagnosed and treated at an early stage. If gingivitis is controlled at an early stage, it will be cured and will not develop into periodontitis. Once it develops into periodontitis, after timely treatment, periodontitis will also be stilled and will not continue to develop and form more serious consequences at a later stage. So once the gum enlargement appears, it proves that there is inflammation in the gums and must be taken seriously and should be treated in a timely manner.
