Frequent bleeding of gums is a sign of gingivitis and periodontitis, and the treatment is ultrasonic scaling and periodontal scaling. The factors leading to gingivitis and periodontitis are poor oral hygiene habits, tartar, soft tartar and bacteria accumulation on the tooth surface and in the teeth. Tartar and bacteria release toxins that cause gingivitis and periodontitis. The most typical symptoms of these two inflammatory diseases are bleeding from brushing, bad taste in the mouth, and receding gums. Ultrasonic scaling can remove tartar and plaque and eliminate gum inflammation. For patients with particularly deep periodontal pockets, further periodontal scaling is required to remove the deep tartar. After the gum and periodontal inflammation disappears, the gum bleeding phenomenon will also disappear. In addition, patients with hypertension, chronic liver disease and blood disorders may also experience spontaneous gum bleeding, which requires treatment of the specific disease and removal of the cause to solve the problem of bleeding gums.
