Brief Answer: Vitamin C deficiency, infection , see Dr Detailed Answer: Hi and thanks for the query, Bleeding gums need very keen attention. However, it might be very useful to know for how long you have been experiencing the bleeding gums. The commonest cause of bleeding gums is an insufficient in take of Vitamin C. Vitamin C is gotten mainly from fruits and oranges. Supplementation of Vitamin C, with tablets could be taken, preferably in the morning hours to avoid sleep disturbances. Knowing if the bleeding is also experienced in other sites is as well important. For instance, prolonged bleeding in case as wound is sustained, would demand a deep evaluation for clotting factors and other bleeding disorders. this would require measuring clotting time, Prothrombin time and measuring the level of platelets in the blood. Liver disease could cause a deficiency in Vitamin K needed to make clotting factors, that could cause bleeding disorders. But this should not be the likely situation as far as the description you just gave is concerned. Brown and slightly greenish tongue is a rare condition, It is important to know for how long you noticed the change in the tongue. any notion of pain, swelling or abnormal smell should be noted. In case you have had a recent rhinitis, it is possible that fluid could drain from nostrils to the mouth and stain the tongue. Your diet should also be noted, for certain foods could change the appearance and tongue color. A complete clinical review by your primary care doctor is needed. The state of the mouth, mouth hygiene, any possibility of infection of gums shall be noted. I suggest you see a primary care doctor. But the description dies not suggest anything much serious, you really need not be bothered at this point in time. Thanks and kind regards as I wish you the best of health. Please, do feel free asking follow up questions in case you got any special concerns. Wishing you the best of health. DR Bain
