The reasons for frequent bleeding gums are as follows:: 1. Local factors: periodontal disease can cause periodontal tissue lesions, making the gums edematous, capillary congestion, and easy to cause teeth bleeding when brushing or biting hard objects. Tartar adhesion, which can lead to gum redness and swelling, can also cause gum bleeding after stimulation. There are also gum wedge defects, which can cause gum hyperplasia and can also cause gum bleeding; 2. Systemic factors: such as blood disorders and coagulation factor deficiency, which can cause gums to bleed easily and bleed more than once. There are also patients with high blood pressure, which may develop gum hyperplasia, which is also prone to cause gum bleeding. Tooth often bleeding need to go to the hospital for blood test analysis to determine the specific cause. In general, it is due to tartar accumulation that causes gum inflammation and irritation resulting in gum bleeding, and a full mouth tartar cleaning and scaling will achieve better results.
