In our daily life, many people can cause bleeding gums when brushing teeth or eating, such as eating steamed buns, nibbling apples, spots of blood can be seen on the food, in fact, healthy gums do not bleed when brushing teeth or eating, so why do gums bleed? Most of them are because the plaque (bacteria) on the tooth surface is not removed in time, the calcium ions in saliva calcify the plaque and slowly form tartar, the gums of the corresponding parts are stimulated by tartar for a long time, resulting in the gums becoming bright red or dark red, swelling, thickening of the edges, the gums are no longer close to the tooth surface, in general, the patient has no pain and no conscious symptoms, only in the mechanical stimulation when brushing or eating, so that the inflammatory state The gums are prone to bleeding, but the bleeding stops soon after the stimulus is removed, and there is no pain, so it is often ignored, and then the treatment is not timely, so that the gingivitis, which is not difficult to treat, gradually develops into a serious periodontal disease. According to the World Health Organization, the prevalence of periodontal disease is about 40%-75%. Gum bleeding is an early clinical symptom of periodontal disease, so attention to the treatment of bleeding gums is extremely beneficial to oral health. In medicine, “gum bleeding” is divided into two categories: passive bleeding and active bleeding: 1. Passive gum bleeding: only under mechanical stimulation such as brushing, biting hard objects or sucking can cause gum bleeding, and in heavier cases, there will be blood in the mouth in the morning, or even blood on the pillow due to saliva outflow, and accompanied by heavy bad breath. In women during pregnancy, due to endocrine changes and imbalance of female hormone secretion, gum inflammation will increase, with local redness and swelling, and even the formation of one or more tumor-like protrusions, called “gingival tumors during pregnancy”. Gum bleeding can be caused by slight stimulation. 2, active gingival bleeding: often related to the patient’s general health status, in the treatment of oral diseases at the same time should take into account the general situation. (1) Patients with leukemia have a large number of immature leukocytes in the peripheral blood, which infiltrate and accumulate in the gum tissue, resulting in swelling of the gums in the whole mouth, which can lead to persistent bleeding of the gums due to the decrease in the number of platelets and is not easy to stop. (2) Patients with cirrhosis of the liver, due to hypersplenism, the reduction of platelets and clotting factors, resulting in gum bleeding. (3) Patients suffering from hypertension and arteriosclerosis will have active gum bleeding due to increased vascular fragility and easy rupture of capillaries. At this time, it is not easy to take simple intraoral methods to stop bleeding and thus must be combined with medical treatment to be effective. In short, for gum bleeding, we should pay great attention to it and treat it seriously, whether it is passive or active gum bleeding, we should go to the hospital for examination and treatment in time, if it is bleeding caused by local plaque and tartar stimulation, remove local irritants and carry out thorough dental cleaning commonly known as “scaling” or periodontal scaling, which can receive good results. It is recommended that you should pay attention to oral hygiene and brush your teeth after meals with a soft-bristled toothbrush with a small head, and brush for at least 3 minutes each time, and use dental floss. In order to reduce the formation of plaque, to reduce and treat the purpose of gingivitis. For active gum bleeding caused by systemic diseases, in addition to local hemostatic treatment and good oral hygiene, you should also go to the internal medicine department to identify the cause of bleeding and confirm the diagnosis of systemic diseases, and then treat the cause in order to completely cure gum bleeding.
