Gingivitis has a high incidence rate, and the initial symptoms are not obvious, which many people overlook. Gingivitis is caused by the presence of a large amount of dental plaque and tartar on the gums. Long-term bacteria can cause inflammation of the gums, resulting in swollen and painful gums. Severe cases may often experience bleeding gums. If not treated promptly, the inflammation can further develop into periodontal inflammation, causing periodontal atrophy. This leads to insufficient periodontal protection around the tooth roots, bleeding, loose teeth, and tooth loss, severely affecting health. Therefore, it is essential to treat gingivitis promptly and pay more attention to oral hygiene to maintain healthy teeth.
