Patients who have gums that bleed more than once and bleed spontaneously are advised to go to the hospital for a coagulation quadruple test and routine blood tests to check for coagulation disorders as well as bleeding disorders such as leukemia. This is because these diseases may cause the gums to bleed more than once, or if the patient has a long-term habit of taking anticoagulant drugs, such as aspirin. If these diseases are ruled out, then periodontitis and gingivitis can be considered. If the patient only has bleeding when brushing teeth or when biting hard objects, which will be relieved by itself afterwards, this may be caused by gingivitis or periodontitis, and the patient is suggested to perform periodontal basic treatment, and after periodontitis and gingivitis are controlled, the symptoms of bleeding gums will generally be relieved.
