 First of all you have to understand that bleeding of gums is a direct warning of gum disease. In general, it suggests existence of gingivitis which in its turn means inflammation of the gums. If gingivitis left untreated, it gets changed to periodontal disease.
Bleeding Gums Causes
 Gingivitis is the main cause which involves inflammation of the gum margin in the region of the necks of the teeth. The cause of plaque is gingivitis. This is a covering of bacteria that collects on the teeth over some period of time. And you probably know that the cause of plaque is eating sugary food or drink and not cleaning the teeth regularly.
Pregnancy is another cause of bleeding gums. Hormone modifications make the connective tissue in the gums weaker and softer. Besides, the increment in blood intensifies the chance of bleeding.
Such factors as stress, poor diet, smoking, rough or crooked teeth all cause bleeding of gums.
Your bleeding gums can be triggered by uncontrolled diabetes and the side effects of some medications.
It is rare but happens that vitamin C deficiency (scurvy), leukemia and hemophilia cause bleeding gums.
Anticoagulants like Coumadin (warfarin) and heparin
