Teeth do not have vascular structures and do not bleed. Usually, the term dental bleeding refers to bleeding gums. There are many causes of frequent bleeding from the gums, such as repeated mechanical stimulation, pregnancy, periodontal disease, and diseases that affect blood clotting. Excluding cases caused by simple factors, medical treatment is usually required. 1. Repeated mechanical stimulation: if the patient has the habit of repeatedly sucking on the teeth, flossing with toothpicks, or incorrect brushing methods, this can cause the capillaries in the corresponding gum area to rupture, resulting in frequent bleeding. 2. Pregnancy: pregnant women also have frequent gum bleeding, which may be related to changes in estrogen levels in the body, or due to a lack of vitamin C, etc. The gum may appear as an early pregnancy reaction; 3, periodontal disease: such as dental caries, calculus, periodontal inflammation, gum tumor, etc., gum hyperplasia or inflammation, breakage, etc., in case the disease is not cured, the gum wrapped around the teeth will have a swollen performance, a little stimulation, such as brushing, eating hard texture food, will easily lead to local breakage and cause bleeding, because the gum swelling is persistent without treatment, so patients will bleed frequently; 4. Diseases affecting coagulation: such as liver disease, blood system diseases, or having diabetes or hypertension, can lead to abnormal coagulation factors in the body and coagulation dysfunction, causing patients to bleed easily. This bleeding may be spontaneous mucosal bleeding or bleeding caused by the rupture of irritated capillaries, and patients may show frequent bleeding from the gums. Therefore, in daily life patients should avoid bad habits that cause frequent bleeding of the gums, while paying attention to oral hygiene and vitamin C supplementation. If the situation of frequent bleeding gums does not ease or improve after correcting the bad habits, patients should actively seek medical examination. If it is caused by periodontal disease, you need to visit a dentist. If it is a disease that affects blood clotting, you need to go to the relevant department for examination and treatment.
